Global transport CO₂ emissions in the net zero scenario 2010-2050, by mode

Global road transportation emissions reached almost six billion metric tons of carbon dioxide (GtCO₂) in 2022. Under the IEA's Net Zero Emissions (NZE) by 2050 scenario, emissions from road vehicles would need to fall to below 1.5 GtCO₂ by 2040. This pathway would require the accelerated deployment of electric cars and other low-emissions fuels. Overall, transportation CO₂ emissions would need to drop below 600 MtCO₂ by 2050.

全球道路交通碳排放量在2022年已接近六十亿吨二氧化碳（GtCO₂）。根据国际能源署（IEA）提出的2050年实现净零排放（NZE）情景，道路车辆排放量需在2040年前降至1.5 GtCO₂以下。此路径需要加速推广电动汽车及其他低碳燃料。总体而言，交通运输领域的二氧化碳排放量需在2050年前降至600 MtCO₂以下。
