Over the past two decades, the UK's carbon dioxide emissions have consistently declined, dropping by approximately 41% from 2000 to 2022, with the most significant reductions coming from the power sector [UK emissions data from IEA. Shaanxi Province emissions are calculated by iGDP based on the Energy Statistical Yearbook for energy-related carbon dioxide emissions.]. By 2024, the carbon intensity of the UK grid is expected to fall to around 125 gCO2eq/kWh, marking a historic low. This is primarily due to a landmark shift in the UK's power structure: the complete phase-out of coal-fired power, a rapid decline in the share of thermal power, and the swift rise of renewable energy.
近二十年來，英國的二氧化碳排放量基本保持穩定下降態勢，從2000到2022年累計下降了約41%，其中最主要的排放減量來自于電力系統排放的降低[ 英國排放數據來自IEA。陜西省排放為iGDP基于能源統計年鑒核算的能源相關二氧化碳排放。]。到2024年，英國電網的碳強度降低至125 gCO2eq/kWh左右，創下歷史新低。這主要源于英國電力結構中的里程碑式變化：燃煤發電徹底退出歷史舞臺，火電占比快速下降，可再生能源電力快速崛起。
