Reference is first made to FIG. 1, illustrating an emission tracking platform 100 according to an example embodiment. The emission tracking platform 100 comprises an emission tracking system 110 and one or more entities 105.

An entity can be defined as any greenhouse gas emitting establishment or asset. Some non-limiting examples of an entity include a residential building 105a (e.g. a single-family residence, a townhouse, a condominium, an apartment building, etc.), an industrial facility 105b (e.g. a factory), a commercial facility 105c (e.g. a medical building, an educational building etc.), a power generation facility 105d, a rail transportation means 105e, a marine transportation means 105f, an air transportation means 105g, an on-road and off-road transportation means 105h, and an agricultural facility 105i.

In the various embodiments illustrated herein, the emission tracking system 110 is configured to track one or more greenhouse gas emissions associated with one or more entities 105.

In the various embodiments illustrated herein, greenhouse gas emissions are considered to be generated or associated with an entity 105 if the operation of the entity results in direct or indirect generation of greenhouse gas emissions. For example, for an entity such as an industrial facility 105b, the greenhouse gas emissions associated with the entity 105b will include any greenhouse gas released by the entity 105b itself during its operation as well as any greenhouse gas released by any other entity, such as a power generation facility 105d, due to the power consumption by the entity 105b.

In the various embodiments illustrated herein, tracking may include a variety of steps as discussed here. Some non-limiting examples of tracking including steps such as monitoring, measuring, analyzing and reporting greenhouse gas emission related information associated with an entity 105.

In one example, the emission tracking system 110 includes a first device configured to monitor and/or measure greenhouse gas emissions from an entity 105; log and compile gathered data to generate real time emission measurements; determine total emission output from the entity 105; and transfer the gathered data, measurements and calculations to a second device.

In this example, the second device is configured to receive data, measurements and calculations from the first device; conduct analysis on the received information; determine changes in emissions output to validate compliance; determine amount of greenhouse gas credit or offset (e.g. carbon credit etc.) required or available for trade; facilitate or broker a trade in greenhouse gas emission credit; monitor emission reduction efforts and techniques; and generate and transmit corresponding reports.

In another example, the emission tracking system 110 includes a single device capable of performing the functionalities of both the first device and the second device of the previous example. Emission tracking system 110 is explained in further detail below, particularly in relation to FIGS. 3-7.

Reference is briefly made to FIGS. 2A-2C, illustrating different examples of emission tracking platforms. FIG. 2A illustrates an emission tracking platform 200A according to one example. FIG. 2B illustrates an emission tracking platform 200B according to another example. FIG. 2C illustrates an emission tracking platform 200C according to a further example.

In the illustrated embodiment, the emission tracking system 220B is not in the same physical location as the premises of entity 205, and is communicably coupled to the entity 205 via network 215. In addition, the emission tracking device 220B is communicably coupled to the external processing device 225 via network 215.

In the embodiment illustrated in FIG. 2C, emission tracking platform 200C comprises an entity 205, a network 215, and an emission tracking system 210C. In this embodiment, the functionalities of an emission tracking device, such as the emission tracking devices 220A, 220B of FIGS. 2A and 2B, and an external processing device, such as the external processing device 225 of FIGS. 2A and 2B, are combined into one hardware unit indicated as emission tracking system 210C in FIG. 2C.

The emission tracking system 210C may or may not be located in the same physical location as the premises of entity 205. The emission tracking system 210C is communicably coupled to the entity 205 via network 215.

In the various embodiments of FIGS. 2A-2C, the emission tracking systems 210A, 210B and 210C are configured to track greenhouse gas emissions, corresponding to one or more greenhouse gases, associated with the entity 205. As discussed above, tracking may include one or more non-limiting steps of monitoring, measuring, analyzing and reporting the greenhouse gas emissions associated with the entity 205.

In embodiments where the emission tracking devices, such as devices 220A, 220B of FIGS. 2A, 2B are separate from the external processing devices, such as external processing devices 225 of FIGS. 2A, 2B, the emission tracking devices 220A, 220B may be configured to carry out one or more non-limiting steps of monitoring, measuring, analyzing and reporting emission data, and the external processing device 225 may be configured to carry out the other non-limiting steps of monitoring, measuring, analyzing and reporting emission data.

In another case, the emission tracking devices 220A, 220B may be configured to carry out the monitoring step, and the external processing device 225 may be configured to carry out the measuring, analyzing and reporting steps. In a further case, the emission tracking devices 220A, 220B may be configured to carry out the monitoring, measuring and analyzing steps, and the external processing device 225 may be configured to carry out the reporting step.

Reference is next made to FIG. 3, illustrating an emission tracking platform 300 according to an example embodiment. Emission tracking platform 300 comprises an entity 305, a network 315 and an emission tracking system 310. Emission tracking platform further comprises an emission trading system 330, a regulation system 340 and an external secondary system 360.

In the illustrated embodiment, entity 305 comprises an emission monitoring system 355. The emission monitoring system 355 includes a plurality of primary 350 and internal secondary 352 sources for monitoring and/or otherwise providing information related to greenhouse gas emissions associated with the entity 305.

Primary sources 350 are defined as one or more units, devices and/or systems that are capable of directly monitoring the greenhouse gas emissions from the entity 305. Primary sources 350 may include one or more sensors 370 (e.g. carbon monoxide sensor, carbon dioxide sensor, etc.), emission monitoring devices 375 (e.g. continuous emissions monitoring system or CEM, portable emission monitoring system or PEM, etc.), and/or any other system or equipment capable of directly monitoring one or more types of greenhouse gas emissions from the entity 305.

An entity 305 may have one or more sensors 370 configured to directly measure one or more types of greenhouse gas emissions. For example, an entity 305 may have one or more sensors capable of monitoring greenhouse gas emissions such as nitrogen oxides (NO_x), carbon dioxide (CO₂), oxygen (O₂), methane (CH₄), carbon monoxide (CO) and non-methane volatile organic compounds (CH), among other gases.

In the illustrated embodiment, the emission tracking system 310 is configured to communicate with sensors 370 via network 315 and receive one or more detected greenhouse gas emission information from the sensors 370. In some cases, the emission tracking system 310 comprises an emission tracking device 320 and a separately located external processing device 325, and in such embodiments, the emission tracking device 320 communicably connects with the sensors 370 and receives detected greenhouse gas emission information.

In some cases, the emission tracking device 320 is located within the premises of the entity 305. In some other cases, emission tracking device 320 is located external to the entity 305. The emission tracking device 320 may be connected to the sensors 370 either via a wired connection or a wireless connection.

The emission tracking system 310 may interface with a sensor 370 via an output connection from the sensor 370. For example, the emission tracking system 310 interfaces with the serial output port of the sensor 370. In some cases, such as in cases where no auxiliary output from the sensor 370 is available, the emission tracking system 310 may interface with the sensor 370 via the circuit board of the sensor 370. For example, the emission tracking system 310 is directly wired (e.g. via a direct splice) to the circuit board of the sensor 370.

The emission tracking system 310 may be configured to receive monitored emission data in the form of electrical signals from the sensors 370. The mission tracking system 310 then processes the received signals to convert them into a value or a measurement indicative of emission output from the entity 305. The emission tracking system 310 is additionally configured to compile, log and analyze the determined emission values or outputs.

The emission tracking system 310 may be configured to validate the sensors 370 to ensure that the received signals are accurate. The emission tracking system 310 can accomplish this by checking the sensors 370 for certification. If the sensors 370 are found to be certified by a regulatory body, no further validation may be required. On the other hand, if the emission tracking system 310 determines that the sensors 370 are not certified, the emission tracking system 310 may validate the sensors 370, for example, by carrying out a calibration check.

As illustrated, primary sources 350 in the monitoring system 355 may also include emission monitoring devices 375. Emission monitoring devices 375 may be any systems or devices capable of measuring greenhouse gas emissions from the entity 305. Emission monitoring devices 375 differ from sensors 370 in that the emission monitoring devices 375 are more complex systems than sensors 370 and are typically configured to monitor more than one greenhouse gas emissions from the entity 305. On the other hand, each sensor 370 monitors a unique type of greenhouse gas emission from the entity 305.

The emission monitoring devices 375 may be certified or non-certified systems. The emission monitoring devices 375 may be a third party or original equipment manufacturer (OEM) measuring equipment. As mentioned above, emission monitoring devices 375 may include a certified continuous emissions monitoring system (CEM system), a certified portable emissions monitoring system (PEM system), among other devices.

A CEM system can be defined as a system comprising equipment and programs configured to analyze one or several specific compounds in the gaseous effluent emissions of a discharge unit or an entity 305. A CEM system may quantify the amount of specific compounds emitted per unit time, and process the information for reporting the emissions. The emissions can be reported in any manner, including, for example, in a manner required by the entity 305. In another example, the emissions can be reported in a manner prescribed by a regulation authority, such as a government body. In one example, the emissions are reported in a manner prescribed by the Environmental Protection Act, Ontario Regulation 194/05 (O.Reg. 194/05). A PEM system can be defined as any system able to predict the concentration and emission rate of a contaminant based on correlation(s) with other monitored parameters.

In the illustrated embodiment, the emission tracking system 310 is configured to interface with the emission monitoring devices 375 via network 315 and receive greenhouse gas emission data corresponding to one or more types of greenhouse gas emissions generated by the entity 305. The emission tracking system 310 may be coupled to emission monitoring devices 375 via wired or wireless connections.

The emission tracking system 310 may receive emission data for each monitored greenhouse gas emission in the form of electrical signals from the emission monitoring devices 375. In such cases, the emission tracking system 310 may process the received signals for each type of monitored greenhouse gas and generate a value or a measurement indicative of total emission output for that greenhouse gas generated by the entity 305. The value or measurement may be determined based on hysteresis or statistical analysis of the monitored emission data.

In some cases, the emission monitoring devices 375 may themselves calculate a total emission output for each type of monitored greenhouse gas from the entity 305, and transmit the total emission output data to the emission tracking system 310. In such cases, the emission tracking system 310 logs, compiles and analyzes the received total emission output data for each monitored greenhouse gas for compliance and/or reporting purposes.

The emission tracking system 310 may be configured to validate the emission monitoring devices 375 to ensure that the received signals and data from devices 375 are accurate. The emission tracking system 310 can accomplish this by checking the emission monitoring devices 375 for certification. If the emission monitoring devices 375 are found to be certified by a regulatory body, no further validation may be required. On the other hand, if the emission tracking system 310 determines that the emission monitoring devices 375 are not certified, the emission tracking system 310 may validate the emission monitoring devices 375, for example, by carrying out a calibration check.

In one example, the emission tracking system 310 validates the data received from sensors 370 and/or emission monitoring devices 375 by transmitting a set of test signals to the sensors 370 and/or emission monitoring devices 375. The test signals are selected such that they are within the spectrum of the sensor 370 and/or emission monitoring device 375. For example, in one case, a set of test signals are selected such that one test signal it at a low end of sensor 370 and/or emission monitoring device 375 spectrum, another test signal is at a high end of sensor 370 and/or emission monitoring device 375 spectrum, and other test signals are within the spectrum. In another case, two test signals are selected and transmitted to the sensors 370 and/or emission monitoring devices 375, where the first test signal is at a low end of sensor 370 and/or emission monitoring device 375 spectrum and the second test signal is at a high end of sensor 370 and/or emission monitoring device 375 spectrum.

The test signals are selected such that the responses to the test signals are part of the operational parameters of the sensors 370 and/or emission monitoring devices 375, and can be predicted by the emission tracking system 310. The emission tracking system 310 then monitors the responses to the test signals from the sensors 370 and/or emission monitoring devices 375, and compares the responses to the predicted responses. In the event that the actual responses match the predicted responses, the emission tracking system 310 validates the sensors 370 and/or emission monitoring devices 375.

In another example, the emission tracking system 310 validates the data received from sensors 370 and/or emission monitoring devices 375 by measuring a known parameter of the sensors 370 and/or emission monitoring devices 375, and comparing the known value to the measured value to determine the accuracy of the sensors 370 and/or emission monitoring devices 375. For example, a thermistor can be validated by the emission tracking system 310 by measuring the resistance of the thermistor. The resistance of the thermistor is a principle operating parameter of the thermistor and is, therefore, a known value. The emission tracking system 310 compares the known resistance value of the thermistor with the measured resistance value, and determines if the thermistor is faulty or not based on the comparison.

In some cases, where the emission monitoring devices 375 are configured to monitor more than one greenhouse gas emissions generated, directly or indirectly, by the entity 305, the emission tracking system 310 may be configured to prompt the emission monitoring devices 375 to transmit raw emission data and/or total emission output measurement data for selected types of greenhouse gases only. In some other cases, the emission tracking system 310 is configured to extract or filter out data of interest, i.e. raw emission data and/or total emission output measurement data for selected types of greenhouse gases, from the stream of mixed data received for all types of monitored greenhouse gases.

As illustrated, monitoring system 355 also includes internal secondary sources 352. Internal secondary sources 352 can be defined as one or more units, devices and/or systems within the premises of the entity 305 that provide secondary data that can be used to estimate one or more greenhouse gas emissions associated with the entity 305. The internal secondary sources 352 do not directly monitor the amount of greenhouse gas emissions generated by the entity 305.

Examples of internal secondary sources 352 for an entity, such as a vehicle, may include one or more devices used to determine fuel levels, brake life, tire pressure etc. of the vehicle. Data from these sources can be used by the emission tracking system 310 to estimate greenhouse gas emissions from the vehicle.

In another example, the internal secondary sources 352 for a vehicle may include one or more devices configured to monitor the parameters of the engine of the vehicle. Such devices may include a transponder connected to the on-board diagnostics (OBD) port of the engine to capture engine data through the engine control module (ECM). The transponder may be connected to the OBD port using protocols such as J1939, ISO 15765-4 etc. Engine operation data from the ECM via the OBD port can be used by the emission tracking system 310 to estimate greenhouse gas emissions from the vehicle.

In cases where there is no ECM or the ECM does not provide the necessary data, the internal secondary sources 352 may include other sensors or devices connected to the vehicle or the engine of the vehicle that monitor engine operations. Data from these sensors or devices can be used by the emission tracking system 310 to estimate greenhouse gas emissions from the vehicle.

In another example, where entity 305 is a power generation facility, such as a power generation facility 105d of FIG. 1, the internal secondary sources 352 may include one or more devices configured to interact with and monitor the program logic control (PLC) of the power generation facility.

In another example, where entity 305 is a manufacturing or an industrial facility, such as an industrial facility 105b of FIG. 1, the internal secondary sources 352 may include one or more devices configured to monitor the methods and processes used in the facility.

Similarly, in another example, where entity 305 is a factory or an industrial facility, such as industrial facility 105b of FIG. 1, the secondary systems 360 may include one or more sensors configured to monitor emissions of fluorinated gases such as Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), Sulfur hexafluoride (SF6) & Nitrogen trifluoride (NF3), etc.

While the entity 305 in the illustrated embodiment of FIG. 3 is shown to include primary sources 350, such as sensors 370 and emission monitoring devices 375, and internal secondary sources 352, it may be understood that not all entities 305 include all of these primary and secondary sources for monitoring greenhouse gas emissions. In some cases, the entity 305 may only include primary sources 350 or internal secondary sources 352, but not both. Similarly, in some cases, the entity 305 may only include sensors 370 or emission monitoring devices 375, but not both.

In some other examples, the entity 305 may not be equipped with any of the illustrated primary 350 and secondary 352 sources. In such cases, the emission tracking device 320 may be configured to interface with external secondary system 360 to estimate greenhouse gas emissions generated, directly or indirectly, by the entity 305.

The external secondary system 360 is analogous to internal secondary sources 352 but differs from the latter with respect to its location. Similar to the internal secondary sources 352, data received from the external secondary system 360 can be used to estimate greenhouse gas emissions for entity 305.

While the internal secondary sources 352 are described as sources present within the premises of the entity 305, the external secondary system 360 includes sensors, units, devices and/or systems not located within the premises of the entity 305. In some cases, external secondary system 360 may be located at a different entity. For example, if entity 305 is a power plant, electricity consumption data from households connected to the power plant can be used to estimate the carbon dioxide emissions from the power plant. In this example, the devices or systems that are used to monitor the electricity consumption at the households connected to the power plant constitute the external secondary system 360.

In some cases, the external secondary system 360 may include one or more servers or databases that receive and store emission related data from one or more of the primary sources 350 and internal secondary sources 352 of the entity 305. For example, in an entity 305, such as a household dwelling, the devices or systems configured to measure electrical consumption at the dwelling may be additionally configured to transmit the electrical consumption data to a cloud server. In this example, the cloud server containing the electrical consumption data of the households constitutes an external secondary system 360.

In the illustrated embodiment, platform 300 also includes a regulation system 340, which can be defined as any server or combination of servers operated and maintained by a regulation authority, or a third party receiving information from a regulation authority. A regulation authority may include any regional, provincial, federal and/or international (e.g. United Nations) body. Regulation system 340 is configured to provide regulatory information, such as standards, tax codes, statues, regulations, policies etc., corresponding to one or more greenhouse gasses.

Some non-limiting examples of information provided by the regulation system 340 includes acceptable and non-acceptable amounts of greenhouse gas emissions from an entity; techniques to reduce or minimize greenhouse gas emissions from various entities; fines or penalties associated with certain greenhouse gas emission levels; credits available for reducing greenhouse gas emission levels; tax ramifications of greenhouse gas credits; trade policies for trading greenhouse gas credits, etc.

The emission tracking system 310 interacts with the regulation system 340 via network 315 to receive appropriate regulation information for tracking (e.g. measuring, reporting, etc.) purposes. The regulation system 340 is constantly updated based on changes in existing regulations or introduction of new regulations.

As illustrated, platform 300 also includes an emission trading or trading system 330, which can be defined as a server or a combination of servers configured to facilitate trade of greenhouse gas emission credits between suppliers and buyers. Trading system 330 may include a website, an application, a central forum, an exchange or any other platform allowing individuals to enroll into the platform and carry out a trade. In some cases, the trading system 330 includes a platform where individuals can register and create respective accounts.

The trading system 330 interacts with the regulation system 340 via network 315. The regulation system 340 governs the trading system 330 and provides the framework for trading in greenhouse gas emission credits to the trading system 330. Similarly, emission tracking system 310 interacts with the trading system 330 via network 315 and provides the individuals on the trading system 330 with emission credits availability, emission reports, and other data that may be useful for trading on the platform.

In the illustrated embodiment, platform 300 comprises an emission tracking system 310, which may be a single device, or a collaboration of multiple devices. In the illustrated embodiment, the emission tracking system includes an emission tracking device 320 and an external processing device 325.

The emission tracking device 320 may be any networked computing device including a processor and memory. The emission tracking device 320 interacts with the other systems and devices on the platform 300 via network 315.

The emission tracking device 320 is configured to interact with the monitoring system 355 of the entity 305 and receive one or more of raw emission data (e.g. electrical signals from sensors 370, as discussed above), total emission output measurement (e.g. from emission measuring devices 375, as discussed above), secondary emission related data (e.g. from secondary internal sources 352), or a combination of these.

In some cases, the emission tracking device 320 is required by the regulation system 320 to monitor a particular type of greenhouse gas emission from an entity 305. In such cases, the emission tracking device 320 extracts the relevant emission related information corresponding to the particular type of greenhouse gas emission from all the data received from the monitoring system 355 of the entity 305. Optionally, the emission tracking device 320 can prompt the monitoring system 355 to only monitor the particular type of greenhouse gas emission and/or only transfer emission data related to the particular type of greenhouse gas emission.

In various cases, the monitoring system 355 of the entity 305 may be updated from time to time. This may be done to incorporate new and technologically advanced sensors 370, emission monitoring devices 375 and/or secondary sources within the premises of the entity 305. Such changes may be required by the regulation system 340. Alternatively, such changes may be part of periodic update and maintenance of the entity 305. In such cases, the emission tracking device 320 is configured to interface with any new or additional systems or devices introduced in the monitoring system 355 of the entity 305. This may be accomplished by updating the hardware, software and/or firmware of the emission tracking device 320.

As discussed above, the emission tracking device 320 can receive raw data from the monitoring system 355 and process this data to generate a total emission output measurement for one or more types of greenhouse gas emissions. For example, emission tracking device 320 may receive electrical signals monitored by one or more sensors 370 as part of raw emission data. In such cases, the emission tracking device processes the received data and calculates or generates a value corresponding to the received data. This value indicates the total emission output for a particular type of greenhouse gas generated, directly or indirectly, by the entity 305. In another example, emission tracking device 320 may receive secondary data from one or more internal secondary sources 352, and the emission tracking device 320 may then process the received secondary data to estimate the greenhouse gas emissions generated, directly or indirectly, by the entity 305.

In some cases, the emission tracking device 320 may receive the total emission output measurements from the monitoring system 355 itself, such as, from emission monitoring devices 375. In such cases, the emission tracking device 320 stores and compiles the received measurements for analysis by the external processing device 325.

As discussed above, the emission tracking device 320 is also configured to audit the monitoring system 355, including sensors 370, emission monitoring devices 375 and internal secondary sources 352. An advantage of auditing the monitoring system 355 is to ensure accurate and consistent monitoring and measurement of greenhouse gas emissions generated, directly or indirectly, by the entity 305.

In various cases, the emission tracking device 320 is configured to convert the emission data, including raw data, secondary data and measurement data into a format compatible with external processing device 325. The emission tracking device 320 is also configured to store and catalog emission data in any manner or format that may be prescribed by external processing device 325, regulation system 340, entity 305, or any other interested party.

The emission tracking device 320 is configured to transmit the emission data, in original or converted form, to the external processing device 325. In some cases, the emission tracking device 320 may encrypt the emission data prior to transmission.

The external processing device 325 may be any networked computing device including a processor and memory, such as a computer, workstation, server, or a combination of these. External processing device 325 is configured to interact with other systems or devices of platform 300 via network 315.

The external processing device 325 is configured to receive emission data, including raw data, measurements, secondary data and/or analyses etc. from emission tracking device 320. The external processing device 325 is further configured to analyze and process the received data and generate suitable emission reports.

For example, the external processing device 325 may be configured to analyze the received data to determine a greenhouse gas emission offset or credit for an entity 305 by comparing the total emission outputs from the entity 305 at two separate times, and determining the improvements in the greenhouse gas emissions from the entity 305 in that time period.

On the other hand, the external processing device 325 may also be configured to analyze the total emission output from the entity 305 at a given time, and recommend changes to the entity to reduce the generation of the greenhouse gas emissions from the entity 305.

In some cases, the external processing device 325 may be configured to analyze the received data and detect data tampering. This may be done by comparing the received data for an entity 305 to historical trends available for that entity 305. In addition to the received data, the external processing device 325 can also audit the monitoring system 355 based on the received data.

The external processing device 325 is also configured to generate reports based on the emission data and analysis. The reports may be generated for the regulation system 340, entity 305 or upon a request of another interested party. In some cases, the external processing device 325 may receive report templates that may be provided by a regulation system 340 or entity 305. In such cases, the external processing device 325 is configured to generate reports based on the templates.

The external processing device 325 may generate a variety of reports, including, reports for types of greenhouse gas emissions being monitored, the entity's emission baseline, amount of emissions generated, the monitoring period, total emission output for tax purposes, variation from the baseline, government or industry standard, variation from the standard, amount of carbon offset available for trading, amount of carbon offset required to balance the excess emissions, compliance status, validation information for the monitoring system 355, etc.

In some cases, the generated reports are used by entities 305 or individuals to trade on trading system 330. In some other cases, the generated reports are used by entities 305 or individuals for tax purposes etc.

The external processing device 325 is also configured to communicate with the emission tracking device 320 to instruct the device 320 regarding which greenhouse gas emissions to track within an entity 305. In addition, the external processing device 325 is also configured to communicate with the emission tracking device 320 to instruct the device 320 regarding what data to extract and transmit to the external processing device 325.

In some cases, the external processing device 325 allows entities 305 or individuals to register with the emission tracking system 310 by creating an account. The external processing device 325 may allow an individual to register two or more emission tracking devices 320 in their account. For example, if an individual wants to track greenhouse gas emissions from a number of entities 305 owned or controlled by the individual, the individual may choose to use one emission tracking device 320 per entity. In a scenario where an individual owns a vehicle, a house, and a factory, the individual may register three emission tracking devices 320 in their account, where each emission tracking device 320 is configured to uniquely monitor each of the vehicle, house and the factory. The individuals can also activate or deactivate various emission tracking devices 320 from their account.

In another example, where an individual owns or controls two or more entities 305, the individuals can use the same emission tracking device 320 for all the entities 305. In some cases, the purpose of the emission tracking device 320 can be redefined or changed from the account. This allows the emission tracking device 320 to stop monitoring one entity and start monitoring another entity owned by the individual.

Reference is next made to FIG. 5, illustrating a block diagram 500 of an emission tracking system, such as emission tracking system 310 of FIG. 3, according to an example embodiment. The system 500 is provided as an example and there can be other embodiments of the system 500 with different components or a different configuration of the components described herein.

The communication module 514 can be used by the emission tracking unit 510 to communicate with other devices or computers.

The power unit 516 can be any suitable power source that provides power to the emission tracking unit 510 such as a power adaptor or a rechargeable battery pack depending on the implementation of the emission tracking unit 510 as is known by those skilled in the art.

The memory unit 518 can include RAM, ROM, one or more hard drives, one or more flash drives or some other suitable data storage elements such as disk drives, etc. The memory unit 518 is used to store an operating system 520 and programs 522 as is commonly known by those skilled in the art. For instance, the operating system 520 provides various basic operational processes for the emission tracking unit 510. The programs 522 include various user programs so that a user can interact with the emission tracking unit 510 to perform various functions such as, but not limited to, viewing and manipulating data as well as sending messages as the case may be.

The memory unit 518 may also accept data from one of the input devices, the input module 524, the emission output generation module 526, the emission offset measurement module 528, the report generation module 532 and the audit module 534. The memory unit 518 uses the received data to define and store emission records.

Each emission record may identify a type of emission monitored at an entity, an identifier for the entity, the time of monitoring and the determined greenhouse gas emission output corresponding to the monitored greenhouse gas emission for the entity. The emission record may additionally include the source of emission monitoring (e.g. one or more sensors 370, emission monitoring devices 375, internal 352 and/or external 360 secondary sources), and the emission data received from the sources.

In one embodiment, the memory unit 518 receives customer information and creates customer records. In this embodiment, the emission tracking unit 510 allows customers to register and create accounts as discussed herein. Each customer record can include one or more types of information such as customer identifier (e.g. name, address, etc.), number and identification of entities owned or controlled by the customer, emission sources available to monitor greenhouse gas emissions associated with the entities, emission data received from the emission sources, emission output values corresponding to the emission data, emission offset measurements, emission reports, audit data, among other things.

The emission tracking unit 510 allows the customers to communicate with the unit 510 via input module 524. The customers can log in and view their accounts remotely. The customers can also define the purpose and functionality of the emission tracking unit 510 in terms of entities and types of greenhouse gas emissions to monitor. The customers can additionally define the categories to include in emission reports, and request the generation of one or more emission reports.

The input module 524 interacts with at least one of the memory unit 518 and the databases 530 for receiving emission data associated with one or more types of emissions from an entity. The input module 524 may interface with one or more emission sources, such as one or more sensors 370, emission monitoring devices 375, internal 352 and/or external 360 secondary sources etc., and receive emission data corresponding to greenhouse gas emissions associated with an entity.

The emission output measurement module 528 interacts with at least one of the memory unit 518 and the databases 530 to process the emissions outputs generated from the emission output generation module 526 at various times, and generate a measurement of changes (e.g. improvements, deteriorations etc.) in the greenhouse gas emissions associated with an entity. The emission output generation module 528 generates an emission offset that can be traded using a trading system, such as trading system 330 of FIG. 3. In some cases, a tax grant, a credit, a fine, a penalty or some other consequence may result based on the emission offset measurement generated by module 528.

The databases 530 can be used to store data for the system 500 such as regulation standards, report templates, historical trends etc. The databases 530 can also store other information required for the operation of the programs 522 or the operating system 520 such as dynamically linked libraries and the like.

The audit module 534 audits the various emission sources, such as sensors 370, emission monitoring devices 375, internal 352 and/or external 360 secondary sources etc. The audit module 534 also audits the emission data and calculated or estimated emission output values and offset measurement values. The audit module 534 also audits the reports for compliance.

The emission tracking unit 510 is additionally configured to carry out other functionalities of an emission tracking system, such as emission tracking system 310 of FIG. 3, as discussed in this document.

Reference is again made to FIG. 3 to illustrate an example application of the various embodiments disclosed herein in an agricultural sector. An agricultural entity may include one or more farms and other structures used in farming operations. Such structures may include buildings to house families and workers, as well as livestock, machinery (e.g. tractors, combines, harvesters etc.), and crops. Such structures may store seeds, hay, fodder, grains, fertilizers, pesticides, other chemical substances used in farming, etc. In some cases, the agricultural entity may contain other entities, such as on road and off road entities 105h, residential entity 105a, industrial entity 105b etc. of FIG. 1.

In an agricultural entity, there may be many sources of greenhouse gas emissions. For example, chemicals used in fertilizers, pesticides etc. may be a direct source of greenhouse gas emissions. Similarly, other substances containing one or more chemicals, such as ammonia sulfide, potassium nitrate, potash, hydrogen sulfide, charcoal, etc. may also contribute to greenhouse gas emissions.

Use and operation of farm machinery may also directly or indirectly contribute towards greenhouse gas emissions. As well, use of vehicles, such as on road and/or off road vehicles, in and around the farms and the buildings may also contribute towards the greenhouse gas emissions. In addition, the operation of the farming structures, including barns and buildings, may also directly or indirectly contribute towards the greenhouse gas emissions.

The emission tracking system 310 disclosed herein may be used to determine the amount of greenhouse gas emissions resulting from the various sources of emissions discussed above. For example, an emission monitoring system, such as system 355, may be used to determine the amount of greenhouse gas emissions using sensors 370, secondary sources 352, secondary system 360 etc.

In one example, the amount of greenhouse gas emissions resulting from the use of fertilizers, pesticides or other chemical substances may be determined by the emission tracking system 310 in conjunction with the regulation system 340. In this case, the regulation system 340 may be configured to provide a correlation between the chemicals used in the fertilizers, pesticides etc. and the greenhouse gas emissions resulting from them. Such correlation information may be made available by a government body or a third party based on research or experiment. In a non-limiting example, the regulation system 340 may be configured to provide that the greenhouse gas emissions resulting from every 100 kilograms of a particular kind of fertilizer is approximately 2 grams of nitrous oxide.

In some cases, the regulation system 340 may provide more specific emission related information by taking into account factors such as the type of fertilizer, the concentration of fertilizer, the storage facility for the fertilizer (e.g. open storage, close storage etc.), any other such factors. The regulation system 340 may be similarly configured to provide a correlation between pesticides and/or other chemicals, and greenhouse gas emissions.

Once the correlation information between the fertilizers, pesticides etc. and greenhouse gas emissions is received from the regulation system 340, the emission tracking system 310 may use this information to determine the amount of greenhouse gas produced by the agricultural entity due to the use of such chemicals. The emission tracking system 310 may be configured to do so by applying the information received from the regulation system 340 to the specifics of the agricultural entity, such as the size of the farm as well as volume, amount and weight of the fertilizers, pesticides etc. use on the farm.

In some cases, the emission tracking system 310 may be configured to determine the amount of greenhouse gas emissions from the agricultural entity based on the toxicity characteristics of the sewage wastewater produced by the agricultural entity. Toxicity characteristics may be determined using internal secondary sources 352 and/or external secondary system 360 of FIG. 3. In some cases, the toxicity characteristics may be determined based on a third party analysis and may be directly provided into an emission tracking unit, such as the emission tracking unit 510 of FIG. 5.

In one example, the profile record of a farmer in an emission tracking unit includes entities such as one or more farms, livestock, one or more vehicles and one or more buildings such as a barn. In such cases, there may be many sources of greenhouse gas emissions. For example, cow or cattle burping or belching, livestock waste management and/or biomass burning may result in production of methane. Use of fertilizers and pesticides may result in production of nitrous oxide. Farming systems employed on the farm may also result in emission of greenhouse gases. In addition, burning of carbon based fuels in the vehicles or farm equipments and use of electricity in the buildings may also contribute towards the greenhouse gas emissions. In such cases, the total greenhouse gas emissions associated with this farmer or the corresponding profile record is determined based on the greenhouse gas emissions resulting from each one of these entities.

Reference is next made to FIG. 4, illustrating a process 400 carried out by an emission tracking system, such as the emission tracking system 310 of FIG. 3, according to the teachings herein.

The process begins at step 402. At step 404, the emission tracking system 310 receives a first emission data at a first time. The first emission data corresponds to one or more different types of greenhouse gas emissions generated, directly or indirectly, by an entity, such as entity 305 of FIG. 3. The first emission data may be received from a monitoring system, such as monitoring system 310 of FIG. 3.

In some cases, the first emission data is received from the primary sources, such as sensors, emission measuring devices etc., within the entity 305. In some other cases, the first emission data is received from the internal secondary sources within the entity 305. In some further cases, the first emission data may be received from external secondary sources, such as external secondary system 360 of FIG. 3. The first emission data may also be received from a combination of these sources.

The first emission data includes any data that can be used to determine the amount of greenhouse gas emissions generated from an entity. The first emission data can include direct data from devices, such as sensors, CEMs, PEMs etc., monitoring greenhouse gas emissions directly. The first emission data can also include data from secondary sources, where the data can be analyzed to estimate the amount of greenhouse gas emissions generated from an entity. The secondary sources can be located within the premises of the entity, or remotely from the entity.

At step 406, the emission tracking system 310 analyzes the first emission data received at the first time to determine a first emission output value. The first emission output value indicates the amount of emissions of a particular greenhouse gas generated, directly or indirectly, by the entity.

This emission output value from emission data received at the first time forms an emission baseline. The baseline can be used in several methods for comparison. For example, the baseline can be compared to the industry standard to determine the carbon-offset. The baseline can be used to determine if a new technology or application reduces emissions by comparing before and after emission output values.

In cases where emission data is received from secondary sources, hysteresis or statistical analysis can be done to determine the first emission output value. In cases where emission data is received from primary sources, suitable processes or calculations can be used to convert the received emission data into emission output value.

At step 408, the emission tracking system 310 receives a second emission data at a second time corresponding to the same greenhouse gas or gases for which first emission data was received at step 404. The second emission data is received in any of the ways discussed above in relation to the first emission data.

The second emission data is received after implementing a certain change within the monitored entity 305 or within another entity that affects the greenhouse gas generation at the monitored entity 305. For example, the monitored entity 305 may be equipped with a CO₂scrubber to remove or reduce the amount of CO₂generated by the entity 305. In another example, the monitored entity 305 as well as other entities affecting the greenhouse gas generation at the monitored entity 305 may undergo maintenance and repair to remove inefficient/old equipment. Such emission reduction changes may be recommended by the emission tracking system 310, a regulation system 340 or any other third party system.

At step 410, the emission tracking system 310 analyzes the second emission data received at the second time to determine a second emission output value. The emission data may be converted into an emission output value based on the various teachings herein.

At step 412, the emission tracking system 310 determines an emission offset measurement based on the first and the second emission output values. The emission offset measurement indicates the change in the total emissions generated, directly or indirectly, by the entity between the first time and the second time.

The emission offset measurement is an emission credit in the event that the greenhouse gas emissions generated by the entity 305 have reduced from the first time to the second time. On the other hand, the emission offset measurement is an emission excess in the event that the greenhouse gas emissions generated by the entity 305 have increased from the first time to the second time.

Emission offset measurement can be used for trading, receiving grants and/or other ways of monetization based on regulations and standards governing the greenhouse gas emission framework in a region, province or country. Similarly, in the event of a negative emission offset measurement, fines and penalties can be imposed based on the emission framework in place. The process end at step 414.

Reference is next made to FIG. 6, illustrating a process 600 carried out by an emission tracking system, such as the emission tracking system 310 of FIG. 3, according to the teachings herein. Process 600 is analogous to process 400 of FIG. 4, and differs only in steps 616 and 618.

At step 616, the emission tracking system 310 determines if the first emission output value generated based on first emission data received at first time is within established regulations. The established regulations may be made available by a regulation system, such as regulation system 340 of FIG. 3. The established regulations may be received and stored in the emission tracking system 310, and may be constantly updated based on the changes to the regulations.

If it is established that the first emission output value is not within the established regulations, the process proceeds to step 618. Otherwise, the process proceeds to step 404.

At step 618, the emission tracking system 310 recommends one or more emission reduction techniques that can be implemented within the entity being monitored or other entities that affect the greenhouse gas generated, directly or indirectly, by the monitored entity.

In some cases, the emission tracking system 310 receives a list of one or more emission reduction techniques from the regulation system 340. The regulation system 340 may include a database of emission reduction techniques that may be updated periodically based on research and development in the field. The regulation system 340 may be maintained and updated by municipal, provincial, national and/or international government bodies.

In some cases, the emission tracking system 310 may transmit the emission output values, such as the first emission output value, to the regulation system 340, and the regulation system 340 may recommend appropriate emission reduction techniques based on factors such as type of entity, greenhouse gas emissions being monitored, generated emission output values, and amount of offset needed to balance the emission outputs etc.

In some other cases, the emission tracking system 310 may receive many emission reduction technique recommendations from the regulation system 340, and the emission tracking system 310 may shortlist the suitable emission reduction techniques based on factors such as type of entity, greenhouse gas emissions being monitored, generated emission output values, and amount of offset needed to balance the emission outputs etc.

In yet some other cases, the emission tracking system 310 may itself be equipped with emission reduction techniques, and may recommend one or more suitable techniques based on factors such as type of entity, greenhouse gas emissions being monitored, generated emission output values, and amount of offset needed to balance the emission outputs etc. The process then proceeds to steps 408-412 as discussed above.

In some cases, the emission offset measurement generated at step 412 may be used by the emission tracking system 310 to provide validation for emission reduction techniques recommended at step 618. For example, the emission tracking system 310 may be configured to monitor and log the types of emission reduction techniques recommended at step 618 and the emission offset measurement determined at step 412.

Since not all emission reduction techniques recommended at step 618 may be implemented by the monitored entity or other entities affecting the monitored entity, process 600 may have an optional step of receiving information regarding emission reduction techniques that have actually been implemented by the monitored entity or other entities affecting the monitored entity. In such cases, the emission tracking system 310 is configured to map the emission offset measurements to the implemented emission reduction techniques.

In some cases, the implemented techniques may be recorded in a database or a server of an external secondary system, such as external secondary system 340, and may be received by the emission tracking system 310 from the external secondary system 340.

One example of emission reduction technique that may be recommended by the emission tracking system 310 is a carbon sink. A carbon sink is a way of removing carbon (or other gasses) physically by changing the molecular structure of the gas. This can be done through natural or artificial methods. For example, a natural way to remove CO₂is through photosynthesis, and can be accomplished by planting more trees and plants etc. An artificial method to remove or reduce CO₂is by implementing a carbon scrubber device.

The emission tracking system 310 may, alternatively or additionally, also recommend maintenance programs to reduce carbon emissions. For example, emission tracking system 310 may recommend periodic greasing of the parts in motion on an entity, such as a vehicle or a machine, etc. This technique may increase the efficiency of the entity, and over time, reduce energy consumption by the entity. This reduction of energy may correspond to a reduction of greenhouse gas emission by the entity.

In some cases, the external secondary system 360 may be equipped with a maintenance program database used to record the various maintenance programs implemented for improving the greenhouse gas emissions associated with the entity 305. Such data may be recorded every time a new maintenance program (e.g. scheduled maintenance, greasing of moving parts, etc.) is implemented. In such cases, the emission tracking system 310 interfaces with the external secondary system 360 and determines the emission reduction techniques actually implemented. This data then becomes part of emission data used to determine emission output value for the entity.

Reference is next made to FIG. 7, illustrating a process 700 carried out by an emission tracking system, such as the emission tracking system 310 of FIG. 3, according to the teachings herein.

The process begins at step 702. At step 704, the emission tracking system 310 interfaces with an entity, such as entity 305, to monitor the amount of greenhouse gas emissions generated, directly or indirectly, by the entity 305. The emission tracking system 310 may become active and ready for tracking greenhouse gas emissions by an entity 305 based on a predetermined schedule. Alternatively, the emission tracking system 310 may become active and ready for tracking greenhouse gas emissions by an entity 305 based on an operator intervention.

At step 706, the emission tracking system 310 determines if entity 305 is being directly monitored for greenhouse gas emissions by primary sources, such as primary sources 350 of FIG. 3. The emission tracking system 310 may determine whether or not the entity 305 is equipped with one or more sensors 370 and/or emission monitoring devices 375 (such as CEM, PEM etc.) in order to determine the presence of primary sources 350.

If it is determined that the entity 305 is not being monitored by primary sources, the process proceeds to step 708. Otherwise, the process proceeds to step 712.

At step 708, the emission tracking system 310 determines if the greenhouse gas emissions generated, directly or indirectly, by the entity 305 can be monitored by secondary sources.

In this step, the emission tracking system 310 can determine if internal or external secondary sources, such as internal secondary sources 352 and external secondary system 360 of FIG. 3, are available to provide emission data that can be used to determine (e.g. estimate) the amount of greenhouse gas emissions generated, directly or indirectly, by the entity 305.

If it is determined that the entity 305 cannot be tracked for greenhouse gas emissions using secondary sources, then the process proceeds to step 710. Otherwise, the process proceeds to step 712.

At step 710, the emission tracking system 310 is configured to determine how many primary sources, such as sensors, CEM, PEM etc. are required to monitor the greenhouse gas emissions associated with the entity 305. The emission tracking system 310 can make this determination based on one or more factors such as type of entity 305, size or mass of entity 305, age of entity 305, historical emission trends of entity 305, number of greenhouse gas emissions generated by the entity 305, extent of variations in greenhouse gas emissions throughout the day, extent of variations in the concentration of the greenhouse gas emissions, number of sources of greenhouse gas emissions within the entity 305 etc.

In some cases, the emission tracking system 310 is also configured to determine how many primary sources, such as sensors, CEM, PEM etc. are required to monitor one or more other entities that affect the greenhouse gas emissions associated with the monitored entity 305. From step 710, the method proceeds to step 704.

Next, at step 712, the emission tracking system 310 determines if the monitoring system, consisting of primary and secondary sources of monitoring greenhouse gas emissions associated with the entity 305, is certified. This check may be advantageous to ensure correct and consistent monitoring and measurement of the greenhouse gas emissions associated with the entity 305. At this step, the emission tracking system 310 determines if all of the sources of emission data within the monitoring system are certified.

If it is determined that the monitoring system is not certified, the process proceeds to step 714. Otherwise the process proceeds to step 716. At step 714, the emission tracking system 310 audits the non-certified sources of emission data for compliance with regulation standards. The emission tracking system 310 may receive the standards related information from a regulation system, such as regulation system 340 of FIG. 3.

The emission tracking system 310 may use various tests or checks to determine if the sources of emission data comply with the standards. For example, the emission tracking system 310 can carry out a calibration check as discussed herein to audit the monitoring system. The emission tracking system 310 may alternatively or additionally rely on third party standard measuring companies or systems to provide the necessary checks. The process next proceeds from step 714 to 716.

Steps 716 and 718 of process 700 are analogous to steps 404 and 406 of FIGS. 4 and 6. At step 716, the emission tracking system 310 receives emission data corresponding to one or more greenhouse gas emissions associated with the entity 305. At 718, the emission tracking system 310 determines an emission output value based on the received emission data.

Next, at step 720, the emission tracking system 310 is configured to generate suitable reports based on the generated emission output values for one or more greenhouse gas emissions associated with the entity 305. For example, the emission tracking system 310 may generate one or more reports illustrating types of greenhouse gas emissions being monitored, the entity's emission baseline, amount of emissions generated, the monitoring period, total emission output for tax purposes, government or industry standard, variation from the standard, amount of carbon offset required to balance the excess emissions, etc. The process ends at step 722.

In some cases, the process 700 may proceed with steps 404-412 of FIG. 4 after step 712 of FIG. 7. In some other cases, the process 700 may proceed with steps 404-412, including steps 616 and 618, of FIG. 6 after step 712 of FIG. 7.
