Description

Technical Field

[0001] The present application relates to the technical field of carbon emission accounting, and more specifically, to a method and apparatus for quantifying the contribution of products and services to greenhouse gas emission reduction. Background Art

[0002] In order to meet the challenges of climate change, there is an urgent need for applicable accounting methods to help energy-saving and emission-reduction product manufacturers better identify, sort out and evaluate the greenhouse gas emission reduction contributions brought about by the application scenarios of their own products and services, and then further guide the research and development and innovation of related products, services and solutions in the field of clean technology within the company, and help customers understand the products and services on the market that have a positive impact on the climate. However, traditional product carbon footprint (Carbon Footprint of Product, CFP) and life cycle assessment (Life Cycle Assessment, LCA) focus on quantifying end-to-end greenhouse gas emissions, without considering the most likely baseline scenario, and most of the emission reduction effect calculations simply compare the use phases before and after the emission reduction products are put into operation, without including other phases of greenhouse gas emissions in the product's entire life cycle into the overall quantification range. The quantification method is relatively rough, resulting in a low accuracy in the evaluation of greenhouse gas emission reduction effects. Summary of the invention

The method can be run on Figure 1 In the computer terminal shown, the computer terminal is explained below.

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0052] Figure 2 is a flow chart of a method for quantifying the greenhouse gas emission reduction contribution of products and services according to an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0053] Step S202, obtaining the accounting boundary, which includes: the relative carbon emission increment and emission reduction generated by all products and services with emission reduction contribution sold or officially put into use in the reporting period during their entire life cycle (including direct and indirect impacts on customer production activities);

[0054] In the above step S202, the entire life cycle of the greenhouse gas emission reduction product includes: (1) the raw material procurement and pre-processing stage, which starts with the extraction of resources from nature and ends with the entry of greenhouse gas emission reduction product components into the product production facility; (2) the production stage, which starts with the entry of greenhouse gas emission reduction product components into the production site and ends with the exit of the finished product from the production facility; (3) the product distribution and storage stage, which is the transfer and storage process of greenhouse gas emission reduction products from the production plant to consumers; (4) the use stage, which starts with the consumer or end user owning the greenhouse gas emission reduction product and ends with the discarding of the used greenhouse gas emission reduction product and its transportation to a recycling or waste treatment facility; (5) the recycling and processing stage, which starts with the user discarding the used greenhouse gas emission reduction product and ends with the return of the greenhouse gas emission reduction product to nature as waste or entering another greenhouse gas emission reduction product life cycle.

[0055] It should be noted that the reporting period refers to a specific period of time covered by the accounting, such as one year.

[0056] It should be noted that services that can contribute to greenhouse gas emission reduction also include: services, the entire life cycle of which is integrated with greenhouse gas emission reduction products. When accounting, it is necessary to identify the greenhouse gas emission reduction products corresponding to the service and the life cycle stage they are in. Step S204, distinguish the project types of the greenhouse gas emission reduction products and services and the different baseline scenarios corresponding to the project types.

[0057] In the above step S204, the baseline scenario corresponds to a plurality of greenhouse gas emission scenarios, ie, the greenhouse gas emission scenario that is most likely to occur when the customer does not put the quantified object (products and services) into use.

[0058] Step S206, determining the key greenhouse gas emission stages under the different baseline scenarios;

[0059] Step S208, calculating the greenhouse gas emission reduction contribution of products and services under the different baseline scenarios according to the accounting boundary and the key greenhouse gas emission stages under the different baseline scenarios.

[0060] Through the above steps S202 to S208, the accounting boundary is obtained, and the accounting boundary includes: the relative carbon emission increment and emission reduction generated by all products and services with emission reduction contributions sold or officially put into use in the reporting period during their entire life cycle; distinguishing the project types of the greenhouse gas emission reduction products and services and the different baseline scenarios corresponding to the project types; determining the greenhouse gas key emission stages under the different baseline scenarios; calculating the greenhouse gas emission reduction contributions of products and services under the different baseline scenarios according to the accounting boundary and the greenhouse gas key emission stages under the different baseline scenarios, and conducting data uncertainty analysis on the quantified results to guide subsequent data quality improvements, so as to continuously improve the accuracy and credibility of the quantified results, thereby solving the technical problem of low accuracy of greenhouse gas emission reduction contribution data generated by quantifying products and services with energy-saving and emission reduction effects in related technologies. The following is a detailed description.

[0061] In step S204 of the method for quantifying the greenhouse gas emission reduction contribution of products and services by the above-mentioned emission reduction products, the specific steps for distinguishing the project types of the greenhouse gas emission reduction products and services and the different baseline scenarios corresponding to the project types are as follows: obtaining the project types of the greenhouse gas emission reduction products and services, wherein the project types include: renovation projects applied by customers to existing infrastructure and new projects applied to new infrastructure; determining the first type of baseline scenario corresponding to the renovation project and the second type of baseline scenario corresponding to the new project.

[0062] The specific steps of determining the first type of baseline scenario corresponding to the renovation project and the second type of baseline scenario corresponding to the new construction project are as follows: determining the baseline scenario S1-1 and baseline scenario S1-2 corresponding to the first type of baseline scenario, wherein the baseline scenario S1-1 is to replace the same type of product previously used, and the baseline scenario at this time is the emission scenario before replacement, and the baseline scenario S1-2 is that the same type of product was not originally equipped, and the baseline scenario at this time is the emission scenario before the greenhouse gas emission reduction product is equipped; determining the baseline scenario S2-1, baseline scenario S2-2 and baseline scenario S2-3 corresponding to the second type of baseline scenario, wherein the baseline scenario S2-1 is the emission scenario of being equipped with the same type of product provided by competitors, the baseline scenario S2-2 is the emission scenario when the preset emission requirements are met, and the baseline scenario S2-3 is the emission scenario when there are no similar products on the market.

[0063] Specifically, since the baseline scenarios for reference and comparison of different project types are slightly different, the corresponding GHG emission reduction products are used to match the customer's original infrastructure or new infrastructure, and then the baseline scenarios under different project types are determined. It should be noted that the services are carried out on existing equipment and infrastructure, so they are uniformly classified as renovation projects.

[0064] (1) Baseline scenario corresponding to the renovation project;

[0065] Compared with the period when greenhouse gas emission reduction products and services were not adopted, the greenhouse gas emissions caused by the customer's production activities are reduced after the renovation project is put into operation. Therefore, the baseline scenario of the renovation project is identified as the initial scenario before the customer has adopted greenhouse gas emission reduction products and services, that is, the greenhouse gas emissions generated to the atmosphere before the greenhouse gas emission reduction products are put into operation. Specifically, it can be divided into the following two scenarios:

[0066] Baseline scenario S1-1: Replace the previously used similar products. The baseline scenario at this time is the emission scenario before replacement;

[0067] Baseline scenario S1-2: The same type of products were not originally equipped. The baseline scenario at this time is the emission scenario before the upgrade.

[0068] (2) Baseline scenario corresponding to the new project;

[0069] New projects (such as adding production lines, building new workshops, etc.) will inevitably increase their own greenhouse gas emissions, so the baseline scenario for new projects is a real market choice. Influenced by many factors such as competitive markets, finance, financing, technology, supervision, and conventional practices, the following three major baseline scenarios were finally screened and identified:

[0070] Baseline scenario S2-1: Emission scenario where competitors provide similar products;

[0071] It should be noted that mapping tables are preset for different competitors, and the mapping tables contain emission contribution calculation rules corresponding to the products of different competitors.

[0072] Baseline scenario S2-2: Emission scenario when the preset emission requirements are met;

[0073] Baseline scenario S2-3: Emission scenario with no similar substitute products on the market.

[0074] In some embodiments of the present application, determining the key emission stages of greenhouse gases under the different baseline scenarios includes: obtaining multiple emission stages in the whole life cycle, wherein the multiple emission stages include: raw material procurement and preprocessing stage, production stage, product distribution and storage stage, use stage and recycling stage; in the case of the baseline scenario S1-1, determining the key emission stage as the use stage; in the case of the baseline scenario S1-2, determining the key emission stage as the raw material procurement and preprocessing stage, the production stage and the use stage; in the case of the baseline scenario S2-1, determining that there is no key emission stage; in the case of the baseline scenario S2-2, determining that there is no key emission stage; in the case of the baseline scenario S2-3, determining the key emission stage as the raw material procurement and preprocessing stage, the production stage and the use stage.

[0075] Wherein, in the case of the baseline scenario S1-1, the quantitative result of the greenhouse gas emission reduction contribution of the product is determined as the relative reduction of emissions from the customer's production activities;

[0076] In the case of the baseline scenario S1-2, the quantitative result of the greenhouse gas emission reduction contribution of the product is determined as the relative reduction of emissions from customer production activities - emissions generated in the raw material procurement and pre-processing stages - emissions generated in the production stage;

[0077] Under the baseline scenario S2-1, the quantitative result of the greenhouse gas emission reduction contribution of the product is determined to be zero;

[0078] Under the baseline scenario S2-2, the quantified result of the greenhouse gas emission reduction contribution of the product is determined to be zero;

[0079] In the case of the baseline scenario S2-3, the quantitative result is determined as the relatively reduced emissions from the customer's production activities - emissions generated in the raw material procurement and pre-processing stages - emissions generated in the production stage.

[0080] Table 1

[0081]

[0082] As shown in Table 1, the product life cycle is divided into five stages: "raw material procurement and pre-processing", "production", "product distribution and storage", "use" and "recycling". Based on the principle of trade-offs, key emission stages are identified and the following two situations are ignored: ① Stages that only account for a small part of the emissions in the entire life cycle of the product, such as product distribution and storage, recycling and processing; ② Stages where the emission difference between the two is almost zero compared to the baseline scenario, ① and ② both indicate that the emission reduction effect can be ignored.

[0083] Specifically, (1) Baseline scenario S1-1: Replace the previously used similar products, such as Figure 3 As shown, the baseline scenario at this time is the emission scenario before substitution. In this scenario, the emissions in the product distribution and storage stage and the recycling and processing stage account for a very small proportion and can be ignored; the emissions in the raw material procurement and pre-processing stage and the production stage of similar products before and after substitution are similar, and the difference between the two is very small and almost zero, which can be ignored. Therefore, the contribution of greenhouse gas emission reduction = the relative reduction of emissions in customer production activities.

[0084] (2) Baseline scenario S1-2: No similar products were previously equipped, such as Figure 4 As shown in the figure, the baseline scenario at this time is the emission scenario before the upgrade. In this scenario, the emissions in the product distribution and storage stage and the recycling and processing stage account for a very small proportion and can be ignored; before the upgrade, the customer was not equipped with similar products, and there was no emission generated in the raw material procurement and pre-processing stage and the production stage in the baseline scenario. Therefore, the contribution to greenhouse gas emission reduction = the relatively reduced emissions from customer production activities - the emissions generated in the raw material procurement and pre-processing stage - the emissions generated in the production stage.

[0085] (3) Baseline scenario S2-1: Emission scenario where competitors provide similar products, such as Figure 5 As shown, this method assumes that both can produce the same emission reduction contribution, so the greenhouse gas emission reduction contribution in this scenario is 0.

[0086] (4) Baseline scenario S2-2: Emission scenario under preset emission requirements, such as Figure 5 As shown, since the quantified object has an emission reduction effect, it is assumed that it meets the mandatory requirements of the latest laws and regulations and produces the same emission reduction contribution, so the greenhouse gas emission reduction contribution in this scenario is 0.

[0087] (5) Baseline scenario S2-3: Emission scenario where there are no similar alternative products on the market, that is, the quantified object has a monopoly position and can only use this product, such as Figure 6 As shown, it is equivalent to the baseline scenario S1-2, and the contribution to greenhouse gas emission reduction = the relative reduction in emissions from customer production activities - emissions generated in the raw material procurement and pre-processing stages - emissions generated in the production stage.

[0088] It should be noted that the analysis of key service emissions first identifies the products corresponding to the services provided, then analyzes the impact of the services on the carbon emissions of the relevant products throughout their life cycle (e.g., by extending the life of the product, carbon emissions caused by the production of new equipment can be avoided to a certain extent), and then subtracts the emissions of the service itself (such as service personnel's travel), and obtains the greenhouse gas emission reduction contribution generated by the service = emissions reduced by extending the service life of the product - emissions generated by service personnel's travel. It is understandable that services can avoid greenhouse gas emissions from production activities caused by reproducing new products (including raw material procurement and pre-processing stages, and production stages) by extending the service life of the corresponding equipment.

[0089] In an optional approach, greenhouse gas emissions caused by raw material production, processing and transportation are determined as emissions generated in the raw material procurement and pre-processing stages; greenhouse gas emissions caused by product manufacturing, assembly, packaging and other links are determined as emissions generated in the production stage; based on the availability of data, the project energy saving report calculation method, energy saving rate estimation method and investment payback period estimation method can be used to determine the relatively reduced emissions from customer production activities in the use stage.

[0090] Specifically, (1) the calculation method of emissions during the raw material procurement and pre-processing stages;

[0091] It is necessary to include direct or indirect greenhouse gas emissions caused by raw material production, processing and transportation. For details, please refer to the quantification method for this stage in the carbon footprint.

[0092] (2) Calculation of emissions during the production phase;

[0093] It covers direct or indirect greenhouse gas emissions caused by product manufacturing, assembly, packaging and other links. For details, please refer to the quantification method of this stage in the product carbon footprint.

[0094] (3) Calculation of relative emission reductions during the use phase;

[0095] For products, any of the three calculation methods can be selected based on data availability.

[0096] 1) Project energy saving report calculation method;

[0097] The energy-saving report data of the project acceptance is used as the calculation basis and the following formula is used for calculation.

[0098] C avoided =Q×E u ×EF×GWP×Y

[0099] Where:

[0100] C avoided——relative reduction in emissions from the customer’s production activities, expressed in tons of carbon dioxide equivalent (tCO2e);

[0101] Q——the number of qualified products produced by the device during the statistical period, in product units, depending on the type of product;

[0102] E u ——Relative energy saving per unit of product during the statistical period, in energy medium units;

[0111] E——the total annual energy consumption of the factory or device during the statistical period, in energy medium units;

[0112] R e ——Relative average energy saving rate of the product, %;

[0113] EF – greenhouse gas emission factor of the corresponding energy medium;

[0114] GWP – Global Warming Potential;

[0115] Y——product service life, in years.

[0116] 3) Investment payback period estimation method;

[0117] The average product payback period and energy savings cost percentage are estimated based on historical project information, market research and expert estimates, and are estimated using the following formula.

[0118] C avoided =A c ÷P e ×EF×GWP×Y

[0119] in:

[0120]

[0121] Where:

[0122] C avoided ——relative reduction in emissions from the customer’s production activities, expressed in tons of carbon dioxide equivalent (tCO2e);

[0123] S——Annual sales volume of products during the statistical period, in yuan;

[0124] T b ——Average payback period of the baseline scenario, in years;

[0132] For services, this method extends the service life of the corresponding equipment, thereby avoiding the greenhouse gas emissions from production activities caused by reproducing new products (including raw material procurement and pre-processing stages, and production stages). Emissions generated by service personnel's travel can be calculated by sorting out their travel modes and travel distances, and matching relevant emission factors.

[0137] Y——product service life, in years;

[0138] Y add ——The service life increased due to maintenance, in years;

[0139] R s ——Contribution of field service to maintenance.

[0140] Among them, after completing the calculation of the contribution to greenhouse gas emission reduction, the method also includes: assigning uncertainties ranging from 0% to 15% to the different variables used in the project energy saving report calculation method, energy saving rate estimation method, and investment payback period estimation method used in the relative reduction of emissions from customer production activities during the use phase; using the uncertainty evaluation index of the data of each calculation item through the error propagation method to obtain the total uncertainty of the calculation result, which is used to characterize the uncertainty of the quantitative results of the greenhouse gas emission reduction contribution of the products and services and guide subsequent data quality improvements.

[0141] Specifically, uncertainty analysis is an important part of this method, which aims to guide the improvement of subsequent data quality by comprehensively evaluating the sources of uncertainty in the calculation results, and to improve the accuracy and credibility of the disclosed data. The main ideas of uncertainty analysis are as follows: 1) determine the uncertainty of a single variable in the quantification process; 2) combine the uncertainty of a single variable into the uncertainty of the calculation method; 3) finally combine it into the total uncertainty of the calculation result. Identifying and analyzing the main sources of uncertainty is conducive to the subsequent improvement of data quality.

[0142] (1) Uncertainty of a single variable;

[0143] Original data and secondary data are distinguished according to the data source, and the uncertainty ranging from 0% to 15% is set for each variable based on the authority and representativeness of the data.

[0144] (2) Uncertainty in calculation methods;

[0145] The calculation method in this method only involves multiplication and division operations. The error transfer formula of multiplication and division operations is used to combine the uncertainties of individual calculation items to obtain the uncertainty (%) of the calculation method.

[0146]

[0147] Where:

[0148] U formula ——uncertainty of calculation method, %;

[0149] U1...U n ——Data uncertainty of n calculation items, %.

[0150] (3) The total uncertainty of the calculation results;

[0151] The calculation result is obtained by adding up the data obtained by the corresponding calculation method for all items during the statistical period. Different calculation methods have different degrees of uncertainty, and it is necessary to use the error transfer formula of addition and subtraction operations to conduct uncertainty analysis on the final combined calculation result.

[0152]

[0153] Where:

[0154] U total — the overall uncertainty of the calculation results;

[0155] U f1 ...U fn ——uncertainty of n calculation methods;

[0156] μ1...μ n ——Emission reduction of n projects during the statistical period, in tons of carbon dioxide equivalent (tCO2e).
