GB/T 46879-2025 Technical specifications at the project level for assessment of greenhouse gas emission reductions—Carbon dioxide capture,utilization and storage project

Scope

This document specifies the accounting boundaries and baseline scenarios for greenhouse gas emissions reduction of carbon dioxide capture, utilization, and storage projects, the accounting workflow, accounting methods and data acquisition, carbon dioxide emission calculation, carbon dioxide injection quantity calculation, carbon dioxide emission reduction calculation during the project injection period, and carbon dioxide emission reduction calculation over the project's entire life cycle, as well as data quality management and reporting content and format. This document applies to carbon dioxide capture, transportation, geological utilization, and storage. The utilization and storage include both land and marine applications, with other utilization methods serving as reference. Note: In this document, the term "utilization" in carbon dioxide capture, utilization, and storage projects refers to geological utilization of carbon dioxide, including carbon dioxide oil displacement and carbon dioxide gas displacement, but excludes other conversion utilization methods such as chemical utilization, biological utilization, and mineralization utilization. For calculations involving greenhouse gases other than carbon dioxide (such as methane), they are calculated in carbon dioxide equivalents based on their global warming potential values.
