T/CPPIA 23-2023 Methodology for accounting of greenhouse gas emission reduction for replacing single-use non-degradable products

Scope

Scope: This document specifies the accounting boundaries for greenhouse gas emission reductions from replacing non-degradable disposable products, the determination of baseline scenarios, the calculation of emission reductions, and data monitoring and sources. This document applies to the methodology for accounting for greenhouse gas emission reductions from the recycling of non-degradable disposable plastic and paper products after their use, replacing non-degradable disposable plastic products. Main technical content: 4. Accounting boundaries: The accounting boundaries of this methodology refer to the greenhouse gas emissions generated from the recycling of disposable retail and catering products after their use, which is consistent with the business scope. It does not include the greenhouse gas emissions generated from the production to use process of the products. The types of greenhouse gases include CO2, N2O, and CH4. 5. Determination of baseline scenarios: 5.1 In the baseline scenario, the non-degradable disposable plastic products used are recycled as waste after their service life and then incinerated or landfilled for disposal. 5.2 Compared with the baseline scenario, the use of biodegradable disposable plastic or paper products results in fewer greenhouse gas emissions during the recycling stage after their disposal. 6. Calculation of emission reductions: 6.1 Baseline emissions: Under the baseline scenario, greenhouse gas emissions include two aspects: one is the emissions generated during the transportation and processing of discarded non-degradable disposable plastic products; the other is the greenhouse gas emissions generated during the chemical changes of discarded non-degradable disposable plastic products during landfill or incineration. 6.2 Project scenario emissions: Project scenario emissions include the energy consumption during the transportation and disposal of recycled products and the greenhouse gas emissions generated during the decomposit
