Emissions Reduction Trend (vs 1990 Baseline)
Developed countries (Annex I) aggregate GHG reduction vs 1990 (UNFCCC 2024)
Historical Timeline
First international treaty establishing binding emission targets for developed nations
Industrial structural shifts and renewable power growth cut Annex I emissions
Paris Agreement signed; 195 nations commit to limit warming well below 2°C
Pandemic disruptions and accelerating coal plant retirements push reductions
Annex I emissions reach 18.5% below 1990 (22.3% including land use and forestry)
Key Insights
Divergent Global Paths
While developed nations cut GHG emissions by 18.5% since 1990, total global emissions grew driven by industrialization in emerging markets, making global decoupling essential.
Regional Leaders
The EU has cut greenhouse emissions by over 30% since 1990 and the UK by over 45%, showing that economic growth can be decoupled from carbon emissions.
LULUCF Impact
When including Land Use, Land-Use Change, and Forestry (LULUCF), developed country emissions reductions reach 22.3% below 1990 levels.
