This document replaces GB/T 32151.8-2015 "Greenhouse gas emissions accounting and reporting requirements Part 8: Cement production enterprises" and Compared with GB/T 32151.8-2015, in addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) Changed the term "fuel combustion emissions" to "fossil fuel combustion emissions" and revised the definition (see 3.4, 3.4 of the 2015 edition);

b) Added the terms and definitions of "carbon emissions", "alternative fuels" and "alternative raw materials" (see 3.2, 3.11 and 3.12);

c) Added the requirement for separate reporting of the reporting entity's use of purchased green electricity, alternative fuels, and co-disposal of waste (see 4.1.1);

d) Added "Clinker production accounting and reporting scope" and added the treatment of purchased green electricity (see 4.2);

e) Added "Measurement and Monitoring Requirements" (see Chapter 5);

f) Changed the requirements for obtaining electricity emission factors (see 6.2.4.3, 5.2.4.3 and Table B.2 of the 2015 edition);

g) Added "Carbon emission accounting steps for clinker production" and "Carbon emission accounting boundary for clinker production" (see 6.3 and 6.4).

Introduction

Climate change caused by human activities has been recognized as one of the greatest challenges facing the world and will continue for decades to come.

Climate change will have an impact on human and natural systems and will have an impact on resource availability, economic activities and human Relevant international organizations, countries and regions are formulating and implementing international, regional, national and local carbon emission management programme to reduce greenhouse gas (GHG) concentrations in the Earth's atmosphere and help humanity adapt to climate change.

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

Standards help turn this scientific knowledge into tools to address climate change. Carbon emissions management programs rely on quantification, monitoring and reporting.

GB/T 32151 "Carbon Emissions Accounting and Reporting Requirements" stipulates the requirements for carbon emissions accounting and reporting at different enterprise levels.

For different types of enterprises, their greenhouse gas emission boundaries, measurement and testing requirements, accounting steps and methods, data quality, etc. are specified separately.

Management, report content and format, etc. GB/T 32151 is divided into the following parts.

--- Part 1. Power generation enterprises;

--- Part 2. Grid enterprises;

--- Part 3. Magnesium smelting enterprises;

--- Part 4. Aluminium smelting enterprises;

--- Part 5. Iron and steel production enterprises;

--- Part 6. Civil aviation enterprises;

--- Part 7. Flat glass production enterprises;

--- Part 8. Cement production enterprises;

--- Part 9. Ceramic production enterprises;

--- Part 10. Chemical production enterprises;

--- Part 11. Coal production enterprises;

--- Part 12. Textile and clothing enterprises;

--- Part 13. Independent coking enterprises;

--- Part 14. Other non-ferrous metal smelting and rolling processing enterprises;

--- Part 15. Petrochemical enterprises;

--- Part 16. Oil and gas production enterprises;

--- Part 17. Fluorine chemical industry enterprises.

In order to facilitate domestic and international exchanges, according to the relevant requirements of the United Nations Intergovernmental Panel on Climate Change (IPCC), this series of documents The quantity value is expressed in the form of "International Unit of Quantity of Substance (Element)" or "International Unit of Quantity of Substance (Element)", such as tC for tons of carbon, tCO2 stands for tons of carbon dioxide, tCO2e stands for tons of carbon dioxide equivalent, tCH4 stands for tons of methane, tC/GJ stands for tons of carbon per gigajoules, Nm3 Indicates cubic meters under standard conditions, etc.
