Ministry of Ecology and Environment: "2021 Electricity CO2 Emission Factors" released
On April 28, the Ministry of Ecology and Environment held a regular press conference in April, and Pei Xiaofei, spokesperson of the Ministry of Ecology and Environment, said that recently, the Ministry of Ecology and Environment and the National Bureau of Statistics released the "2021 Electricity Carbon Dioxide Emission Factor". The CO2 emission factor for electricity released this time can be used as a reference for different entities when calculating the CO2 emissions of electricity consumption. In the future, a normalized release mechanism will be established to update and regularly release the carbon dioxide emission factors of electricity in a timely manner, and the "2022 Carbon Dioxide Emission Factors for Electricity" will also be released this year. In addition, the Ministry of Ecology and Environment is organizing a study on the carbon footprint factor of electricity, and will release the carbon footprint factor of electricity when it matures.
Recently, the Ministry of Ecology and Environment and the National Bureau of Statistics released the "2021 Electricity Carbon Dioxide Emission Factor". The CO2 emission factor of electricity is an important basic parameter for calculating the CO2 emissions of electricity consumption. The CO2 emission factor for electricity released this time can be used as a reference for different entities when calculating the CO2 emissions of electricity consumption.
Pei Xiaofei introduced that the power sector is an important source of carbon dioxide emissions, accounting for more than one-third of the total carbon dioxide emissions of global fossil fuel combustion and more than 40% of China's carbon dioxide emissions. The 2021 electricity carbon dioxide emission factors released this time are divided into three calibers: the first is the 2021 national, regional and provincial average electricity carbon dioxide emission factors, which are the unit power generation (including thermal power, hydropower, wind power, nuclear power, The second is the 2021 national average carbon dioxide emission factor (excluding non-fossil energy electricity traded in the market), which is the carbon dioxide emissions per unit of power generation (including the power generation of all the above-mentioned power types, but excluding the non-fossil energy electricity traded in the market), and the third is the carbon dioxide emission factor of the national fossil energy power generation in 2021, which is the carbon dioxide emissions per unit of fossil energy electricity generation (deducting biomass power generation from thermal power). 。
Subsequently, the Ministry of Ecology and Environment will establish a normalized release mechanism to update and regularly release the carbon dioxide emission factors of electricity in a timely manner, and will release the "2022 Electricity Carbon Dioxide Emission Factors" this year. In addition, the Ministry of Ecology and Environment is also organizing a study on the carbon footprint factor of electricity, and will release the carbon footprint factor of electricity when it matures.
