Beijing issues standards on carbon emission calculation 
The Beijing Administration for Market Regulation on December 24, 2020 published local standards collectively called Carbon Dioxide Emission Calculation and Reporting Requirements for the following 6+ industries. All the standards came into effect on January 1, 2021.
- DB11/T 1781-2020 Power generation industry
- DB11/T 1782-2020 Cement industry
- DB11/T 1783-2020 Petrochemical industry
- DB11/T 1784-2020 Heat generation and supply industry
- DB11/T 1785-2020 Service industry
- DB11/T 1786-2020 Road haulage industry
- DB11/T 1787-2020 Other industries
Beijing is one of the pilot carbon markets in China. An accumulated total of 41,430,000 tons of carbon emission allowances has been traded in the city since 2013 as of the end of 2020 with a total value of 1,740 million yuan (approximately $268 million). The local standards, which were developed by considering the characteristics of the structure of Beijing’s industry, set out the scope of the carbon emission calculation and reporting, process of the calculation, requirements for data quality management and reporting, etc. Here is an outline of one of these standards, DB11/T 1783-2020 Petrochemical industry:
Scope
This standard applies to the calculation and reporting of the amount of carbon dioxide emitted by producers of processed petroleum products, basic chemical raw materials and chemical products.
Emissions required to be calculated and reported
The amount of carbon dioxide emitted by fixed or mobile equipment in production systems must be calculated and reported. Production systems are categorized into main production systems, auxiliary production systems and subsidiary production systems.
Equation for total emissions
Total carbon emissions are calculated according to this equation:
Total CO2 emissions (tCO2) = CO2 emissions from fossil fuel combustion + CO2 emissions from industrial operations + CO2 emissions from the consumption of externally purchased electricity + CO2 emissions from the consumption of externally purchased heat
