UNEP Emissions Gap Report 2025 - Chapter 2 Global Emissions Trends

Global greenhouse gas emissions in 2024 reached a record high of 57.7 GtCO2e, growing by 2.6 per cent (1.4 GtCO2e). The growth rate was high compared to recent years and another opportunity was missed to peak emissions. A large share of this years’ emissions growth was due to deforestation and forest degradation emissions in the land use, land-use change and forestry (LULUCF) sector. However, emissions from fossil fuels also continued to increase. Most countries within the G20 registered an increase in GHG emissions, excluding LULUCF. The highest absolute growth in total GHG emissions, excluding LULUCF was observed in India and China, while Indonesia recorded the fastest relative growth in emissions.Several historic high emitting countries such as the USA and Russia have much higher emissions compared to the global average and increased their emissions in 2024. Renewable energy deployments and climate policies avoided even higher emissions growth in 2024, but increased effort will be required to bring a peak in global GHG emissions.
