Introduction

Climate change caused by human activities has been recognized as one of the greatest challenges facing the world and will continue to Climate change will have an impact on human and natural systems and will have an impact on resource availability, economic activities and human In response, relevant international organizations, countries and regions are developing and implementing international, regional, national and local greenhouse gas (GHG) emissions management programs to reduce greenhouse gas (GHG) concentrations in the Earth's atmosphere and help humanity adapt to climate change.

Greenhouse gas emission management plans need to be based on the best scientific knowledge and take effective and progressive measures to address the impacts of climate change.

Standards help transform this scientific knowledge into tools to address climate change. Greenhouse gas emission management programs rely on Relies on the quantification, monitoring and reporting of greenhouse gases.

GB/T 32151 "Greenhouse Gas Emissions Accounting and Reporting Requirements" stipulates the greenhouse gas emissions accounting and reporting requirements at different enterprise levels.

The purpose is to specify the greenhouse gas emission boundaries, measurement and monitoring/testing requirements, accounting steps and Accounting methods, data quality management, report content and format, etc. GB/T 32151 is to be divided into the following parts.
