The method provides a method for calculating the carbon emission benchmark value of each year for various types of manufacturing enterprises (creation type, demonstration type, and leading type) that aim at carbon neutrality. The method is scientific and reasonable, highly operational, and can be used for the calculation and evaluation of carbon emission benchmark values ​​of enterprises in carbon neutral enterprise evaluation and carbon management system certification.

[0021] The above-mentioned object of the present invention is achieved through the following technical scheme: a method for calculating the annual carbon emission benchmark value of the manufacturing industry based on the carbon neutrality goal, characterized in that the annual carbon emission benchmark value E of the enterprise y Calculate as follows:

[0022] E y =E OEy +E SCEy

[0023] E y - The company's annual carbon emissions benchmark value, in tons of CO 2e / 10,000 yuan GDP;

[0024] E OEy - The company's annual operating carbon emissions benchmark value, in tons CO 2e / 10,000 yuan GDP;

[0025] E SCEy - The company's annual supply chain carbon emissions benchmark value, in tons of CO 2e / 10,000 yuan GDP;

[0026] For manufacturing industries whose carbon neutrality goals do not involve carbon emissions from the supply chain, such as air conditioner manufacturers, power plants, photovoltaic companies, etc., E SCEy The value is 0, and the annual carbon emission baseline value of the enterprise is E y It is equal to the company's annual operating carbon emission benchmark value E OEy , so the annual carbon emission benchmark value of the enterprise is E y The calculation can be simplified to:

[0027]

[0028] E OEb —The initial value of the company’s own operating carbon emissions, for example, the data for 2023 can be taken, in t CO 2e / 10,000 yuan GDP;

[0029] y- a year in the company's carbon neutrality plan, such as 2024, 2025, 2030;

[0030] by - the base year, which is the year before the carbon neutrality target year is created, for example, 2023;

[0031] OEty - The year in which the company achieves its net zero carbon emissions target for its operations, for example 2060;

[0032] A-When an enterprise achieves its own net zero carbon emissions target, the proportion of its own operating carbon emissions that cannot be reduced through voluntary emission reductions to its own operating carbon emissions in the base year is, for example, 20%.

[0033] In the present invention, the manufacturing industry includes air conditioner manufacturing enterprises, power plants, and photovoltaic enterprises.

[0034] The manufacturing industry can target creative, demonstrative and leading carbon neutral enterprises.

[0035] The professional terms involved in this application are explained as follows:

[0036] Carbon neutral enterprise type

[0037] Carbon neutral enterprises are divided into three types: creation type, demonstration type and leading type according to the scope of carbon emission accounting, the time of carbon neutrality and the degree of carbon neutrality. Among them:

[0038] Creation of carbon-neutral enterprises requires that enterprises achieve peak net operating emissions in the year of creating the carbon neutrality target, and reduce their net operating emissions to zero before 2060. This includes reducing their operating carbon emissions to 20% of the base year's carbon emissions through voluntary emission reductions, and neutralizing the remaining carbon emissions through carbon offsetting.

[0039] Demonstration carbon neutral enterprises are required to achieve peak net emissions in their operations in the year they set the carbon neutrality goal, and reduce their net emissions to zero by 2050, including reducing their carbon emissions to 20% of the base year through voluntary emission reduction, and neutralizing the remaining carbon emissions through carbon offset; and reduce net emissions in the supply chain to zero by 2060, including reducing carbon emissions in the supply chain to 20% of the base year through coordinated emission reduction, and neutralizing the remaining carbon emissions through carbon offset.

[0040] Leading carbon neutral enterprises are required to achieve their own operating net emissions peak in the year of creating the carbon neutrality target, and reduce their own operating carbon emissions to zero by 2040, including reducing their own operating carbon emissions to 20% of the base year carbon emissions through voluntary emission reduction, and the remaining carbon emissions are neutralized through carbon offset; and reduce the net emissions of the upstream supply chain to zero by 2050. Among them, the supply chain carbon emissions are reduced to 20% of the base year carbon emissions through coordinated emission reduction, and the remaining carbon emissions are neutralized through carbon offset.

[0041] Carbon emission categories According to ISO 14064-1, greenhouse gas sources at the organizational level are classified into the following six categories:

[0042] Category 1: Direct greenhouse gas emissions and removals;

[0043] Category 2: Indirect greenhouse gas emissions from energy input;

[0044] Category 3: Indirect greenhouse gas emissions from transportation;

[0045] Category 4: Indirect greenhouse gas emissions from products used by the organization;

[0046] Category 5: Indirect greenhouse gas emissions associated with the use of products from the organization;

[0047] Category 6: Indirect greenhouse gas emissions from other sources.

[0048] According to the company's carbon neutrality goals, greenhouse gas sources at the organizational level can be divided into the following two categories:

[0049] Operating emissions: The carbon emissions from an organization’s own operations, including direct greenhouse gas emissions and indirect greenhouse gas emissions from removal and input energy, corresponding to Category 1 and Category 2 in ISO 14064-1.

[0050] Supply chain emissions, other related carbon emissions outside of its own operations, including indirect greenhouse gas emissions from transportation, indirect greenhouse gas emissions from products used by the organization, indirect greenhouse gas emissions associated with the use of products from the organization, and indirect greenhouse gas emissions from other sources, corresponding to categories 3-6 in ISO14064-1.

[0051] Net Operating emissions refers to the sum of the company’s own operating carbon emissions and carbon offsets outside the organization.

[0052] Net Supply Chain Emissions - Net Supply Chain emissions are the sum of supply chain carbon emissions and the company's carbon offsets outside the organization. DETAILED DESCRIPTION

[0060] E SCEy - The company's annual supply chain carbon emissions benchmark value, in tons of CO 2e / 10,000 yuan GDP;

[0061] Since the carbon neutrality goal of air conditioner manufacturers does not involve carbon emissions from the supply chain, SCEy The value is 0, so the annual carbon emission benchmark value of the enterprise is E y The calculation can be simplified to:

[0062]

[0067] A- When an enterprise achieves its own net zero carbon emissions target, the proportion of its own operating carbon emissions that cannot be reduced through voluntary emission reductions in the base year is 20%.

[0068] Calculate the company's annual carbon emissions baseline value for 2024 and substitute the data to get:

[0069]

[0070] That is, the company's annual carbon emissions baseline value in 2024 is 9.574t CO 2e / 10,000 yuan GDP.

[0071] According to the above method, the annual carbon emission baseline value E of enterprises from 2025 to 2060 can be calculated. y , after sorting, as shown in the following table:
