T/CECA-G 0257-2023 Carbon Emission Output Efficiency Evaluation Guideline

Scope

Scope: This standard is formulated based on the study of national policies and relevant evaluation standards, and is applicable to the evaluation of carbon emission output benefits in regions, industries, and enterprises in China. It includes terms and definitions, basic principles and requirements, evaluation index systems, and evaluation methods, etc. Main technical content: (1) Evaluation scope. The evaluation is conducted on a natural year cycle. (2) Evaluation boundaries. Regions are evaluated based on administrative boundaries; industries are evaluated according to the boundaries defined in the "National Economic Industry Classification" (GB/T 4754-2017); and enterprises are evaluated based on legal person boundaries. (3) Principles and requirements of the evaluation process. The evaluation should adhere to the principles of scientificity, accuracy, legality, and compliance. (4) Evaluation methods: 1) For regional evaluation, a multi-indicator weighted evaluation method is used; 2) For industry evaluation, the unit carbon emission tax (yuan/ton of carbon dioxide) is used for evaluation; 3) For enterprise evaluation, there are two scenarios. The first is for regions to evaluate the unit carbon emission output benefits of enterprises within their scope, using a "economic-technical dual matrix" comprehensive evaluation method; the second is for enterprises to self-evaluate their own unit carbon emission output benefits, using a combination of limited indicators evaluation and indicator grading weighted evaluation methods.
