背景:随着中国发电技术进步、电力结构调整,电网供给单位千瓦时电力所需的化石燃料减少。单位度电的二氧化碳排放、甲烷排放、一氧化二氮排放也相应降低。使用数据库中原有的2018年之前的中国电力数据作为输入,不考虑电网的变化以及区域电力结构的特点,会导致产品生命周期环境影响(包括碳足迹)偏高。基于此,为真实反映产品因消耗电力而产生的环境影响,本文更新了全国和各省单位度电(供电)化石燃料的消耗量,以及温室气体排放量。

Update Log for China’s Electricity Database

April 4, 2021, by Ecovane

BackgroundWith the development of technology in electricity generation and the changes to the ratio of different sources of electricity supply, the consumption of fossil fuels, as well as the emission of greenhouse gases per kWh electricity supply, has decreased evidently. Applying the outdated generic electricity data developed several years ago for LCA may lead to higher pollutant emission and environmental impact than reality. To calculate the environmental impact more accurately, Ecovane updated the consumption of fossil fuels and GHG emissions per kWh electricity supply for China's national grid and provincial grid.
