2026 Global Carbon Budget records 38.2 Gt fossil CO2, 0.4% below 2025

Global Carbon Project data show China emissions declining 0.9% after two years of flat growth while land-use change emissions rose, pushing total CO2 to 43.3 billion tonnes. The remaining 1.5°C carbon budget stands at 150 billion tonnes, or under four years at current rates. Land sinks recovered from the 2023-24 El Niño but face renewed pressure from the 2026 event.

Prior Global Carbon Budget editions documented repeated near-peaks followed by rebounds; the 2026 decline repeats the pattern of temporary oil shocks rather than structural decoupling. IEA capacity statistics confirm solar and wind additions accelerated yet still trail the trajectory required for sustained global reduction. Professor Friedlingstein and Glen Peters both note that one-year drops without durable policy or technology lock-in do not constitute a peak.

Operationally, the 0.4% drop signals that incremental clean-energy deployment can offset demand growth but remains insufficient to reverse the atmospheric accumulation rate. Governments tracking Nationally Determined Contributions must therefore treat the 2026 figure as a warning threshold, not evidence of trajectory change. Next-year data releases will test whether capacity growth exceeds the 25% increment needed to convert this single-year dip into a multi-year decline.
