[0037] In order to more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Figure 1 As shown, a greenhouse gas inventory system 1 of a preferred embodiment of the present invention is used to implement the greenhouse gas inventory method of this embodiment. The greenhouse gas inventory system 1 includes a server 10 and a database 20. The server 10 is used to execute a greenhouse gas inventory program and connect to the database 20. The server 10 can be connected to multiple electronic devices 30 via a network 40. The network 40 can be, for example, the Internet or a local area network. Each of the electronic devices 30 can be, for example, a computer, a mobile phone, a tablet computer, etc. that can be connected to the network. Each of the electronic devices 30 is operated by a user of an enterprise or organization. The server 10 and the database 20 can be located on the same host, or they can be located on different hosts and connected through the network 40.

[0038] The database 20 includes a questionnaire database 22 and an emission coefficient database 24. The questionnaire database 22 stores a plurality of predetermined emission source identification questionnaires, and the plurality of predetermined emission source identification questionnaires correspond to a plurality of industries, such as cement industry, panel manufacturing industry, integrated circuit manufacturing industry, automobile industry, communication network industry, etc. The aforementioned industries are merely examples and are not limited thereto. Each of the predetermined emission source identification questionnaires includes a plurality of options, and the plurality of options correspond to a plurality of emission sources. The plurality of emission sources may, for example, correspond to at least category 1 and category 2 of ISO 14064-1:2018, or may further correspond to categories 3 to 6. The plurality of predetermined emission source identification questionnaires are designed for various industries, and various emission sources that will be used by various industries are pre-selected, and then designed in the form of electronic questionnaires, so that each emission source has a corresponding option for user selection.

[0039] Taking the cement industry as an example, the multiple emission sources may include multiple emission sources of direct greenhouse gas emissions (category 1) and multiple emission sources of indirect greenhouse gas emissions from input energy (category 2), wherein the multiple emission sources of direct greenhouse gas emissions may include fixed combustion emission sources (diesel, natural gas, 4-6 heavy oil, etc.), mobile combustion emission sources (diesel, gasoline for vehicles, liquefied petroleum gas, etc.), industrial process emission sources (acetylene, welding rods, CO2 cylinders, etc.), and human fugitive emission sources (water fertilizer and septic tanks, carbon dioxide fire extinguishers, etc.); the multiple emission sources of indirect greenhouse gas emissions from input energy may include purchased electricity, purchased steam, purchased heat, etc.). The multiple emission sources may also include indirect greenhouse gas emissions caused by transportation (category 3), indirect greenhouse gas emissions caused by the use of products by organizations (category 4), indirect greenhouse gas emissions caused by the use of products from organizations (category 5), and indirect greenhouse gas emissions caused by other sources (category 6).

[0040] The emission coefficient database 24 stores an emission coefficient of a greenhouse gas (such as carbon dioxide CO2, methane CH4, nitrous oxide N2O, etc.) from multiple emission sources. For example, the emission coefficient of the greenhouse gas corresponding to the emission source of motor gasoline is 2.2631328720 metric tons / metric ton, and the emission coefficient of the greenhouse gas corresponding to the emission source of water fertilizer and septic tank is 0.0000127500 metric tons / person-day. Of course, the same emission source can also correspond to multiple greenhouse gases.

[0041] The greenhouse gas inventory system 1 described above can be used to execute the greenhouse gas inventory method of this embodiment, including: Figure 2 Steps shown.

[0042] Step S11: setting basic data of a project for an inventory project, wherein the basic data of the project includes an industry category.

[0043] In this embodiment, the user can operate the electronic device 30 to connect to the server 10, and the server 10 provides a project setting interface, which is transmitted to a screen display of the electronic device 30. The user can set the basic project data of the inventory project through the electronic device 30. In addition to the industry, the basic project data may also include company name, factory type, company location, inventory year, inventory clause version, IPCC GWP version, power coefficient selection year, inspection unit, etc.

[0044] Step S12: Select one of the predetermined emission source identification questionnaires in the questionnaire database 22 corresponding to the industry category according to the industry category of the project basic data to form an emission source identification questionnaire, wherein the emission source identification questionnaire includes multiple options, and the multiple options correspond to multiple emission sources respectively; provide a selection interface for the emission source identification questionnaire for a user to select multiple options from the multiple options to form multiple selected options.

[0045] In this embodiment, the server 10 obtains the industry in the basic data of the project, and selects a corresponding one from the questionnaire database 22 according to the industry, and the selected predetermined emission source identification questionnaire forms the emission source identification questionnaire. Taking the cement industry as an example, the selection interface 60 of the emission source identification questionnaire 50 is as follows: Figure 3 As shown, the selection interface 60 is transmitted to the electronic device 30 and displayed on the screen, and is presented in the form of an electronic questionnaire for the user to select multiple options 50a, each option is a question related to an emission source, and the user can select option 50a, for example, by checking a box, and option 50a is selected after being checked. The user can enter a custom emission source name for each selected option on the selection interface 60, so that the user can identify the purpose of the emission source of each selected option in the subsequent steps. In addition, each of the options 50a of the emission source identification questionnaire also corresponds to an emission form of each emission source. The aforementioned emission form can be, for example, fixed, mobile, process, fugitive, or purchased electricity.

[0046] The multiple options 50a of the emission source identification questionnaire 50 mentioned above are illustrated by the examples of options of Category 1 (direct greenhouse gas emissions) and Category 2 (indirect greenhouse gas emissions from input energy), that is, the emission source identification questionnaire 50 includes at least a direct greenhouse gas emissions questionnaire 52 and an input energy indirect greenhouse gas emissions questionnaire 54, wherein the multiple emission sources corresponding to the multiple options 50a of the direct greenhouse gas emissions questionnaire 52 belong to multiple direct greenhouse gas emission sources, and the multiple emission sources corresponding to the multiple options 50a of the input energy indirect greenhouse gas emissions questionnaire 54 belong to multiple input energy indirect greenhouse gas emissions sources.

[0047] Option 50a of the emission source identification questionnaire 50 may also include options for Category 3 (indirect greenhouse gas emissions caused by transportation), Category 4 (indirect greenhouse gas emissions caused by the use of products by the organization), Category 5 (indirect greenhouse gas emissions caused by the use of products from the organization) and Category 6 (indirect greenhouse gas emissions caused by other sources). That is, the emission source identification questionnaire 50 may also include a questionnaire on indirect greenhouse gas emissions caused by transportation, a questionnaire on indirect greenhouse gas emissions caused by the use of products by the organization, a questionnaire on indirect greenhouse gas emissions caused by the use of products from the organization, and a questionnaire on indirect greenhouse gas emissions caused by other sources.

[0048] In addition, in this embodiment, the server 10 can also provide a significant indirect emission source scoring table and an indirect emission source evaluation table for the user to connect the electronic device 30 to set the contents of the significant indirect emission source scoring table and the indirect emission source evaluation table.

[0049] Step S13: generating an identification result 70 according to the plurality of selected options selected by the user, wherein the identification result 70 includes the plurality of emission sources corresponding to the plurality of selected options.

[0050] Since each of the options 50a corresponds to one of the emission sources, the server 10 can determine the corresponding emission source according to the selected option in the emission source identification questionnaire 50 and generate the identification result ( Figure 4 The identification result 70 also includes the names of the custom emission sources corresponding to the emission sources.

[0051] Through the above steps S11 to S13, since the emission source identification questionnaire 50 already has various emission sources that may be used by the industry and is presented to the user in the form of an electronic questionnaire, the user can select through the option 50a in the emission source identification questionnaire 50 corresponding to the industry to form a selected option. Therefore, it helps the user to identify the emission sources used by the enterprise or organization, which can improve the efficiency of the user's greenhouse gas inventory.

[0052] After the emission source is identified, the greenhouse gas inventory method of this embodiment may further include the following steps:

[0053] Step S14: providing an input interface for the user to input activity data of each emission source in the identification result 70 to form an emission source list, wherein the emission source list includes the multiple emission sources in the identification result 70 and the activity data of each emission source.

[0054] In this embodiment, the server 10 transmits the input interface 80 ( Figure 5Reference) to the electronic device 30 and displayed on the screen, the user inputs the activity data of the plurality of emission sources through the electronic device 30 to form Figure 5 The emission source list 82 is shown. The activity data may be, for example, the activity data of the whole year of the inventory year, but is not limited thereto, and may also be the activity data of half a year, quarter, or month. The emission source list 82 also includes the custom emission source names corresponding to the emission sources. When the user enters the activity data, the user can identify the emission source by the custom emission source name to avoid input errors.

[0055] Step S15: Obtain an emission coefficient of a greenhouse gas corresponding to each of the emission sources from the emission coefficient database 24 according to the plurality of emission sources in the emission source list 82 .

[0056] In this embodiment, the server 10 obtains the greenhouse gas and its emission coefficient corresponding to each emission source from the emission coefficient database 24 based on the emission source and the emission form in the emission source list 82 ( Figure 6 Reference).

[0057] Step S16: Calculate an emission amount of the greenhouse gas corresponding to each emission source according to the activity data of each emission source in the emission source list 82 and the emission coefficient.

[0058] In this embodiment, the server 10 calculates the greenhouse gas emissions of each emission source based on the activity data and emission coefficient of the emission source list 82 ( Figure 7 Reference). The server 10 also calculates the carbon dioxide equivalent (CO2e) of each emission source based on the GWP, calculates the carbon dioxide emission equivalent of category 1 (direct greenhouse gas emissions), and the carbon dioxide emission equivalent of category 2 (indirect greenhouse gas emissions from input energy). The server can also calculate the carbon dioxide emission equivalent of each category 3 to 6, and the total carbon dioxide emission equivalent of categories 1 to 6.

[0059] Through the above steps S14 to S16, the activity data of each emission source identified can be obtained, the emission coefficient of each emission source can be obtained, and the greenhouse gas emission coefficient of each emission source can be calculated.

[0060] In addition, step S16 of this embodiment further includes:

[0061] The server 10 obtains an inventory template from an inventory template database.

[0062] In this embodiment, the database 20 includes the inventory template database 26, which stores a plurality of predetermined inventory templates, each of which corresponds to a version of an inventory clause, such as ISO 14064-1:2018 or ISO 14064-1:2006, wherein the clause version of ISO 14064-1:2006 has categories 1, 2, and 3, and category 1 corresponds to category 1 of ISO 14064-1:2018, category 2 corresponds to category 2 of ISO 14064-1:2018, and category 3 corresponds to categories 3 to 6 of ISO 14064-1:2018. The server 10 obtains and corresponds to the predetermined inventory template from the inventory template database 26 according to the clause version of the project basic data in step S11 to form the inventory template.

[0063] The server 10 generates an inventory list of the inventory project based on the emission source list 82, the greenhouse gas emissions of each emission source and the inventory list template. Therefore, the inventory list generated by the server 10 is the text version of the basic data of the project.

[0064] Furthermore, an inventory report can be generated based on the inventory list. For example, the server 10 can provide another input interface to the electronic device 30, allowing the user to input the basic data of the company through the other input interface, and the server 10 can generate the inventory report with the basic data of the company. Therefore, the time of the user to type the inventory report can be effectively saved.

[0065] The inventory list and inventory report of the inventory project can be stored in the database 20 for subsequent query and use. In one embodiment, the server 10 can also generate uncertainty assessment results and data quality management assessment results from the inventory list.

[0066] The above is an explanation of how to generate an inventory list and an inventory report for a single inventory project. The same user of the same enterprise or organization, or different users, can use the greenhouse gas inventory system 1 to establish individual inventory projects for the enterprise's branches or different plant areas to generate inventory lists and inventory reports for the corresponding inventory projects, and integrate the inventory lists of multiple inventory projects into one, as explained below.

[0067] The same user or different users can connect to the server 10 through their electronic device 30 to make the greenhouse gas inventory system 1 repeat the above steps S11 to S16 multiple times to generate multiple inventory lists of multiple inventory projects.

[0068] Selecting multiple of the multiple inspection projects to form a project group. The user connects to the server 10 via the electronic device 30 and selects multiple inspection projects of the same enterprise or organization, and the server 10 forms the selected inspection projects into a project group.

[0069] The server 10 integrates the inventory lists of the multiple inventory projects in the project group to form an integrated information interface 90 ( Figure 8 ), the integrated information interface 90 includes a total carbon dioxide emission equivalent of the plurality of inventory projects in the project group, and a separate total carbon dioxide emission equivalent of each inventory project. The integrated information interface 90 can display the aforementioned total emission equivalent and / or the plurality of separate total emission equivalents in text and / or chart. Therefore, it provides users with an overview of greenhouse gas inventory information for different branches or different plants of the same enterprise or organization.
