Description

Technical Field

[0001] This invention relates to the field of carbon emission technology, and in particular to a method, apparatus, equipment, medium and product for calculating carbon emissions in responsible user communities. Background Technology

[0002] Low-carbon communities are a key task in my country's low-carbon and zero-carbon technology research and development initiative in urban and rural construction. Accelerating the construction of green communities is seen as a crucial step in promoting the low-carbon transformation of urban and rural construction and management models, requiring a shift away from the point-based nature of carbon emissions from individual buildings to achieve multi-scale integrated carbon reduction across buildings, building complexes, and communities. Achieving top-down low-carbon development goals requires bottom-up support from scientifically quantifiable methods. Currently, community carbon emission indicators have been incorporated into the community planning and construction indicator system, requiring that the carbon reduction rates of newly built and existing urban communities be no less than 20% and 10%, respectively.

[0003] However, for building complexes, and even for neighborhoods, communities, and urban areas that consider more complex factors such as outdoor environment and infrastructure, a unified method for quantifying community carbon emissions has yet to be established. Current community carbon emission calculation systems lack unified boundaries, and the carbon emission calculation items vary, resulting in a lack of comparable data. Furthermore, the calculation results are granular, only presenting the total and average carbon emissions of the community, ignoring the differences in the behavior of the actors involved. They fail to represent the carbon emissions of responsible users within the total and average community carbon emissions, thus failing to support accurate traceability of carbon emission responsibility. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a method, apparatus, equipment, medium and product for calculating carbon emissions of responsible users in a community. It clearly defines the calculation boundary of community carbon emissions, and can accurately calculate the carbon emissions of responsible users by using a rule of total calculation and redistribution to households, which makes it impossible to directly measure the carbon emissions of responsible users. This supports accurate traceability of carbon emission responsibility in the later stage.

[0005] To achieve the above objectives, embodiments of the present invention provide a method for calculating carbon emissions in a responsible user community, comprising: determining the calculation boundary of community carbon emissions based on different sources of carbon emissions; wherein, the calculation boundary includes building carbon emissions, public facility carbon emissions, carbon emission reductions from renewable energy sources, carbon sinks in green spaces, and carbon trading;

[0006] The carbon emissions from buildings of responsible users, carbon emissions from public facilities, carbon reductions from renewable energy sources, carbon sinks in green spaces, and carbon trading are calculated separately.

[0007] The carbon emissions from the public facilities, the carbon reductions from the renewable energy sources, the carbon sinks from the green spaces, and the carbon trading are respectively allocated to the responsible users;

[0008] The community carbon emissions of the responsible users are calculated based on the building carbon emissions of the responsible users, as well as the carbon emissions of public facilities allocated to the responsible users, carbon reductions from renewable energy sources, carbon sinks in green spaces, and carbon trading.

[0009] As an improvement to the above scheme, the building carbon emissions of the responsible user include building operation carbon emissions, building implicit carbon emissions, and building carbon offsetting.

[0010] The carbon emissions from building operations include carbon emissions from energy use and carbon emissions from water use; wherein, the carbon emissions from water use include carbon emissions from water supply and carbon emissions from wastewater treatment.

[0011] The carbon emissions from buildings include carbon emissions from building material production, building material transportation, building construction, building demolition, waste transportation, and waste disposal.

[0012] The calculation method for building carbon offsetting is as follows:

[0014] The carbon offset of construction waste recycling is obtained by multiplying the total carbon reduction from the recycling and reuse of construction waste by a preset value.

[0015] As an improvement to the above scheme, the carbon emissions of public facilities include carbon emissions from the operation of public facilities, carbon emissions implicit in public facilities, and carbon offsetting of public facilities.

[0016] The carbon emissions from the operation of public facilities include carbon emissions from energy consumption and carbon emissions from water use; wherein, the carbon emissions from water use include carbon emissions from water supply and carbon emissions from wastewater treatment.

[0017] The carbon emissions implied by public facilities include carbon emissions from building material production, building material transportation, public facility construction, public facility demolition, waste transportation, and waste disposal.

[0018] The calculation method for carbon offsetting of public facilities is as follows:

[0019] The total carbon reduction from the recycling of public facility waste is calculated based on the amount of public facility waste generated, the recycling rate of building material waste, the carbon emission factor of virgin building materials, and the carbon emission factor of recycled building materials.

[0020] The carbon offset of public facility waste recycling and reuse is obtained by multiplying the total carbon reduction from public facility waste recycling and reuse by a preset value.

[0021] As an improvement to the above scheme, the allocation of carbon emissions from public facilities, carbon reductions from renewable energy sources, carbon sinks in green spaces, and carbon trading to the responsible users includes:

[0022] Based on the building area of ​​the responsible user and the total building area of ​​the community, the carbon emissions of the public facilities, the carbon reduction of the renewable energy, and the carbon sink of the green space are respectively allocated to the responsible user;

[0023] The carbon transactions are allocated to the responsible users based on their transaction amounts and the total transaction amount of the community.

[0024] As an improvement to the above scheme, the calculation formula for carbon trading is as follows:

[0025]

[0026] In the formula, TCE EX E represents the total amount of community carbon trading during the calculation period, in kgCO2; i EF represents the amount of green electricity traded in the i-th transaction, in kWh; e,0 EF represents the local power grid's average carbon emission factor, kgCO2 / kWh; e,i The green electricity carbon emission factor for the i-th transaction is expressed as kgCO2 / kWh; CE ex,j Represents the amount of other carbon trading in category j, in kgCO2;

[0027] The carbon trading allocated to the responsible users is then:

[0028]

[0029] In the formula, PCE EX The carbon trading volume allocated to responsible users during the calculation period is expressed in kgCO2; PEV represents the trading amount participated in by responsible users, in yuan; and TEV represents the total trading amount of the community, in yuan.

[0030] As an improvement to the above scheme, the formula for calculating the community carbon emissions of the responsible user is as follows:

[0031] PCE = PCE B +PCE S -PCE RE -PCE GL -PCE EX ;

[0032] In the formula, PCE represents the total community carbon emissions of the responsible user during the calculation period, in kgCO2; PCE B PCE represents the building carbon emissions of the responsible user during the calculation period, in kgCO2; SPCE represents the carbon emissions of public facilities allocated to responsible users within the calculation period, expressed in kgCO2; RE PCE represents the carbon emission reductions from renewable energy allocated to responsible users within the calculation period, expressed in kgCO2.

When the computer program or computer instructions are executed by a processor, they implement the responsible user community carbon emission calculation method described above.

[0040] Compared to existing technologies, the beneficial effects of the method, apparatus, equipment, medium, and product for calculating community carbon emissions by responsible users provided in this invention are as follows: By determining the calculation boundary of community carbon emissions based on different sources of carbon emissions, the calculation boundary includes building carbon emissions, public facility carbon emissions, carbon reduction from renewable energy sources, carbon sinks in green spaces, and carbon trading. The building carbon emissions, public facility carbon emissions, renewable energy carbon reduction, green space carbon sinks, and carbon trading of responsible users are calculated separately. The public facility carbon emissions, renewable energy carbon reduction, green space carbon sinks, and carbon trading are allocated to the responsible users respectively. Based on the building carbon emissions of the responsible users and the public facility carbon emissions, renewable energy carbon reduction, green space carbon sinks, and carbon trading allocated to them, the community carbon emissions of the responsible users are calculated.

This supports accurate traceability of carbon emission responsibility in the future. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figure 1 , Figure 1 This is a flowchart illustrating a preferred embodiment of a method for calculating carbon emissions in a responsible user community provided by the present invention. The method for calculating carbon emissions in a responsible user community includes:

[0049] S1. Determine the calculation boundary of community carbon emissions based on different sources of carbon emissions; wherein, the calculation boundary includes building carbon emissions, public facility carbon emissions, carbon emission reductions from renewable energy sources, carbon sinks in green spaces, and carbon trading;

[0050] S2, calculate the building carbon emissions of the responsible user, the carbon emissions of the public facilities, the carbon emission reduction of the renewable energy, the carbon sink of the green space, and the carbon trading, respectively;

[0051] S3, the carbon emissions from the public facilities, the carbon reduction from the renewable energy sources, the carbon sinks of the green spaces, and the carbon trading are respectively allocated to the responsible users;

[0052] S4. Calculate the community carbon emissions of the responsible user based on the building carbon emissions of the responsible user, as well as the carbon emissions of public facilities allocated to the responsible user, carbon reduction from renewable energy sources, carbon sinks in green spaces, and carbon trading.

[0053] It should be noted that the current boundaries for calculating community carbon emissions lack uniformity, and the calculation items vary. Generally, they can be categorized into four types: ① Energy carbon emissions, mainly from electricity, fossil fuels, and heat consumption in buildings and infrastructure; ② Transportation carbon emissions, from energy consumption during residents' outings and internal community transportation; ③ Living carbon emissions, including items related to residents' breathing, food, drinking water, solid waste, and household garbage; ④ Green space carbon sinks, mainly considering carbon absorption and storage in public green spaces within the community. The specific considerations for each calculation item also differ. For ①, some cases only consider residential buildings, while others consider energy consumption from public buildings and community environmental facilities; for ②, all cases consider internal community transportation, but there are different opinions on whether commuting inside and outside the community should be included in the calculation; ③ shows the greatest inconsistency, with most cases only including domestic waste and sewage treatment, some including food consumption, clothing consumption, and even carbon emissions from residents' breathing, and some cases not including water consumption or including water in ①; for ④, all cases use internal community green spaces as the benchmark for carbon sink calculation, but the distinction between specific lawns, shrubs, or trees varies, resulting in significant uncertainty in the actual calculation.

[0054] The intensity of carbon emissions in a community is influenced by numerous factors, including the region's energy structure, the mixed nature of surrounding functions, the built environment, energy-saving technologies, residents' living standards, and daily behaviors, resulting in significant uncertainty. Therefore, it is necessary to trace responsibility from the consumption end, addressing each case individually. However, current practices typically rely on statistical analysis of total energy consumption, transportation, water usage, and waste generation within the community, then calculating per capita or per household averages based on the community's population and number of households. While this method provides total and average carbon emissions and describes the macro-level distribution and trends of carbon emissions, it ignores the differences among stakeholders, inevitably failing to accurately identify carbon emission sources and hotspots, thus hindering the traceability of carbon emission responsibility and the development of carbon reduction strategies. To achieve peak carbon emissions while meeting residents' continuously rising living standards, low-carbon technologies alone are insufficient; a combination of economic and administrative measures is needed to promote green lifestyles such as low-carbon travel and proper waste management. These are closely related to individual residents' behavior, but cannot be reflected in the total and average carbon emissions of the community. Therefore, the first requirement is to trace carbon emissions more precisely and implement the responsibility of users to reduce carbon emissions in order to develop a systematic governance strategy.

[0055] Based on this, embodiments of the present invention provide a method for calculating carbon emissions in responsible user communities. This method defines and standardizes the boundaries of the community carbon emission calculation system, focusing on buildings, community public facilities, and renewable energy and green space carbon sinks generated within the community's land area, while also considering the calculation needs corresponding to new carbon neutrality methods such as carbon trading. On the other hand, it excludes carbon emissions from daily life and transportation, which are not within the scope of urban and rural construction accounting. Furthermore, it refines the carbon emission calculation units and data collection methods within the boundaries of the community calculation system, ensuring that the calculation results can be matched to responsible users and supporting the subsequent development of control measures for these users.

[0056] Specifically, in this embodiment of the invention, the boundaries of the community carbon emission calculation system are first determined based on different sources of carbon emissions. Please refer to [link / reference]. Figure 2 , Figure 2 This is a schematic diagram of the calculation system boundary in a responsible user community carbon emission calculation method provided by this invention. The calculation system boundary includes building carbon emissions throughout the entire lifecycle of buildings within the community boundary, carbon emissions throughout the entire lifecycle of public facilities within the community boundary, carbon emission reductions generated from renewable energy production such as solar and wind power within the community boundary, carbon sinks of various green spaces within the community boundary, and carbon trading. Carbon trading refers to transactions between certain community stakeholders (e.g., individuals, families, organizations, or the community as a whole) and national or municipal carbon markets, including purchasing carbon emissions to increase the community's carbon emissions, or conversely, reducing the community's carbon emissions through selling carbon emissions. It should be noted that refined carbon emission diagnosis is the primary step in assessing community carbon emissions, identifying carbon reduction potential at both the community-wide and individual point levels, tracing carbon emission responsibility, and formulating carbon reduction strategies. Therefore, data measurement units should be minimized while meeting feasibility requirements. Therefore, this invention proposes a community carbon emission calculation method based on "responsible users," which refers to entities within the community that bear direct or indirect responsibility for carbon emissions, including residents, businesses, and public institutions. These users generate carbon emissions through daily activities (such as energy consumption and transportation) and may also participate in carbon reduction and carbon sink management. Figure 2 Carbon emission carriers typically have carbon emission data measurement conditions as shown in Table 1 below, which can be divided into two categories: one category can be directly measured to the household, such as building carbon emissions, which can be collected at the user level through household electricity meters, water meters, etc.; the other category cannot be directly measured to the household, such as electricity for lighting in community public spaces and water for cleaning, which can be statistically calculated based on the total amount and then allocated to the household according to verified accounting rules.

[0057] Table 1. Measurement Conditions and Allocation Methods for Community Carbon Emission Data

[0058]

[0059] Therefore, this embodiment of the invention directly calculates the building carbon emissions of responsible users for buildings whose carbon emissions can be directly measured at the household level. For carbon emissions from public facilities, carbon reductions from renewable energy sources, carbon sinks from green spaces, and carbon trading that cannot be directly measured at the household level, the total community carbon emissions are first calculated and then allocated to responsible users. Finally, based on the building carbon emissions of responsible users and the carbon emissions from public facilities, carbon reductions from renewable energy sources, carbon sinks from green spaces, and carbon trading allocated to responsible users, the community carbon emissions of responsible users are calculated.

[0060] In another preferred embodiment, the building carbon emissions of the responsible user include building operation carbon emissions, building implicit carbon emissions, and building carbon offsetting.

[0061] The carbon emissions from building operations include carbon emissions from energy use and carbon emissions from water use; wherein, the carbon emissions from water use include carbon emissions from water supply and carbon emissions from wastewater treatment.

[0062] The carbon emissions from buildings include carbon emissions from building material production, building material transportation, building construction, building demolition, waste transportation, and waste disposal.

[0063] The calculation method for building carbon offsetting is as follows:

[0064] The total carbon reduction from the recycling of construction waste is calculated based on the amount of construction waste, the recycling rate of building materials, the carbon emission factor of virgin building materials, and the carbon emission factor of recycled building materials.

[0065] The carbon offset of construction waste recycling is obtained by multiplying the total carbon reduction from the recycling and reuse of construction waste by a preset value.

[0066] For details, please refer to Figure 3 , Figure 3 This is a schematic diagram of the building lifecycle stages as defined by ISO 21930. Carbon emissions within the system boundary include embodied carbon emissions and operational carbon emissions, specifically: modules A1-A3, A4-A5, B1-B5, and C1-C4 generate embodied building carbon emissions; modules B6 and B7 generate operational carbon emissions; carbon offsetting outside the system boundary is the recycling and reuse of module D. In this embodiment of the invention, the building carbon emissions of the responsible user include operational carbon emissions, embodied building carbon emissions, and carbon offsetting from the recycling and reuse of building materials outside the system boundary, i.e.:

[0075] Carbon emissions from water use include carbon emissions from water supply and carbon emissions from wastewater treatment, namely:

[0076] PCE b，w =PCE b，ws +PCE b，wd ;

[0077] PCE b,ws =WS b ×EF ws ;

[0078] PCE b,wd =WD b ×EF wd ;

[0079] In the formula, PCE b,ws Indicates the carbon emissions from water supplied by the responsible user, kgCO2; PCE b,wd Indicates the carbon emissions from wastewater of the responsible user, kgCO2; WS b Indicates the water supply volume to the responsible user, in tons (t); EF ws This indicates the carbon emission factor of municipal water supply, kgCO2 / t; WD b This represents the drainage volume of the responsible user, t, which is considered equivalent to WS.b ;EF wd This represents the carbon emission factor from municipal wastewater treatment, expressed in kgCO2 / t.

[0080] Hidden carbon emissions from buildings include carbon emissions from building material production, building material transportation, building construction, building demolition, waste transportation, and waste disposal.

[0081] PCE B，E =PCE b，m +PCE b,t1 +PCE b，c +PCE b，d +PCE b，t2 +PCE b,w ;

[0082] The formula for calculating carbon emissions from building materials production is as follows:

[0083]

[0084] In the formula, M b,i This indicates the amount of building materials used by the responsible user of type i, in tons (t) and cubic meters (m³). 3 etc; EF m,i This indicates the carbon emission factor of various building materials, expressed in kgCO2 / unit.

[0085] The formula for calculating carbon emissions from building material transportation is:

[0086]

[0087] In the formula, T b,i D represents the weight (t) of the i-th type of building materials transported by the responsible user. b,i EF represents the transportation distance of the i-th type of building materials, in km; t,i Let represent the carbon emission factor per unit weight of transport distance under the i-th type of building material transportation method, kgCO2 / (t·km).

[0088] The formula for calculating carbon emissions from building construction is:

[0100] Carbon offsetting in construction is the amount of carbon offset from the recycling and reuse of construction waste, calculated based on the amount of construction waste generated. The specific calculation method is as follows:

[0101] First, based on the amount of construction waste, the recycling rate of building materials, the carbon emission factor of virgin building materials, and the carbon emission factor of recycled building materials, the total carbon reduction from the recycling of construction waste is calculated using the following formula:

[0102]

[0103] In the formula, PCE b,mr The amount of carbon reduction from the recycling and reuse of construction waste is expressed in kgCO2; r i EF represents the recycling rate of the i-th type of building material waste, in %; m,i EF represents the carbon emission factor of the i-th type of virgin building material, kgCO2 / unit; mr,i This represents the carbon emission factor (kgCO2 / unit) of the i-th type of recycled building materials.

[0104] The formula for calculating the recycling rate of building material waste is as follows:

[0105] r i =1-w i .

[0106] Then, multiply the total carbon reduction from the recycling and reuse of construction waste by a preset value to obtain the carbon offset for construction waste recycling and reuse. The calculation formula is as follows:

[0107]

[0108] In the formula, PCE B,D The value represents the building carbon offset in kgCO2; a% represents the preset value.

[0109] For example, the carbon offset of construction waste recycling is calculated as 50% of the total carbon reduction from the recycling of construction waste, i.e.:

[0110]

[0111] It should be noted that regarding "carbon offsetting outside the system boundary," since the recycling and reuse of building material waste occurs between two building / public facility lifecycles, a question arises: to whom should the carbon reduction benefits be distributed? Please refer to [link / reference needed]. Figure 4 , Figure 4 This is a schematic diagram illustrating the carbon offset data allocation in a responsible user community carbon emission calculation method provided by this invention. The World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) have proposed two methods, one of which is called the "Producer Benefit Approach" (WRI). 100-0 The approach of deducting the embodied carbon emissions associated with recyclable materials in the previous life cycle is called the "Recycler Benefit Approach" (WRI). 0-100 The remaining amount is deducted in the next lifecycle. This embodiment of the invention adopts a compromise, allocating the remaining amount equally across the two lifecycles, so only 50% is included at the boundary of this community system.

[0112] In yet another preferred embodiment, the carbon emissions from public facilities include carbon emissions from the operation of public facilities, carbon emissions implicit in public facilities, and carbon offsetting by public facilities;

[0113] The carbon emissions from the operation of public facilities include carbon emissions from energy consumption and carbon emissions from water use; wherein, the carbon emissions from water use include carbon emissions from water supply and carbon emissions from wastewater treatment.

[0114] The carbon emissions implied by public facilities include carbon emissions from building material production, building material transportation, public facility construction, public facility demolition, waste transportation, and waste disposal.

[0115] The calculation method for carbon offsetting of public facilities is as follows:

[0116] The total carbon reduction from the recycling of public facility waste is calculated based on the amount of public facility waste generated, the recycling rate of building material waste, the carbon emission factor of virgin building materials, and the carbon emission factor of recycled building materials.

[0117] The carbon offset of public facility waste recycling and reuse is obtained by multiplying the total carbon reduction from public facility waste recycling and reuse by a preset value.

[0118] Specifically, in this embodiment of the invention, carbon emissions from community public facilities are similar to building carbon emissions, including carbon emissions from the operation of public facilities, implicit carbon emissions from public facilities, and carbon offsetting of public facilities outside the system boundary, i.e., TCE.
