T/BJEA 0001-2023 Carbon Capture, Utilization, and Storage Project Greenhouse Gas Emission Reduction Accounting Methods and Reporting Guidelines

Scope

Main Technical Content: Project Greenhouse Gas Emission Reduction Accounting and Reporting Workflow, Carbon Capture, Utilization, and Storage. The accounting of greenhouse gas emission reductions for CCUS projects should strive to be comprehensive, accurate, and transparent. The calculation of emission reductions should follow a step-by-step process to ensure the scientific and reasonable nature of the accounting results. The full-process CCUS project greenhouse gas emission reduction accounting and reporting workflow mainly includes the following steps: (1) Identification of CCUS projects and analysis of project process flows; (2) Determination of project accounting boundaries and baseline scenarios; (3) Identification of emission sources and greenhouse gas emission types for the project and baseline scenarios; (4) Calculation of project greenhouse gas emission reductions, including: a) Selecting appropriate accounting methods based on emission sources and greenhouse gas types; b) Selecting and obtaining production data, activity data, and emission factor data related to greenhouse gas emissions; c) Calculating emissions for the CCUS project and baseline scenarios separately; d) Calculating and summarizing greenhouse gas emissions for the project and baseline scenarios; e) Calculating the project's greenhouse gas emission reductions. (5) Quality assurance of accounting work: project monitoring and data quality management; (6) Preparation of project greenhouse gas emission reduction reports. Determination of project boundaries and baseline scenarios An important prerequisite for conducting greenhouse gas emission reduction accounting for CCUS projects is to determine the project's accounting boundaries. Only by defining the project's accounting boundaries can we ensure that the calculation of greenhouse gas emissions during the CCUS process does not omit or duplicate data. A baseline scenario is a hypothetical situation that
