Global fossil-fuel CO₂ emissions are projected to fall 0.4% in 2026, to 38.2 billion tonnes, as solar, wind and electric vehicles meet much of rising energy demand. The decline is not yet evidence of a lasting emissions peak: oil emissions are expected to drop 1.9%, partly because the Iran conflict has disrupted energy markets, while coal emissions rise 0.6%. Including land-use change, which is projected to emit 5.1 billion tonnes, total CO₂ emissions increase to 43.3 billion tonnes. The remaining carbon budget for limiting warming to 1.5°C is about 150 billion tonnes - less than four years at current emissions - and atmospheric CO₂ is projected to reach 427.7 parts per million.

Emissions are forecast to decline in China, the United States, the European Union and Japan, but rise 4.4% in India. China leads clean-technology deployment and forest-based carbon uptake; globally, solar and wind avoided an estimated 4.1 billion tonnes of emissions in 2025. A separate analysis finds that clean technologies could offset 64-79% of emissions from new energy demand through 2028, and that 59 countries grew their economies while emitting less in 2025 than in 2019. Still, electrification and carbon removal remain limited, deforestation continues to outweigh some forest gains, and the 2026 El Niño may affect natural carbon sinks. Researchers argue that faster clean-energy deployment and expanded CO₂ removal are needed for a durable global decline.
