Global fossil fuel CO2 emissions are projected to fall 0.4% in 2026 to 38.2 billion metric tons, but total emissions including deforestation are expected to reach a record 43.3 billion. ScienceDaily reported on the Global Carbon Budget from the Global Carbon Project, which links the fossil fuel decline partly to growing solar and wind generation and to disruption from the Iran conflict, with oil emissions down 1.9% in a temporary energy shock. Solar, wind and electric vehicles are meeting roughly two-thirds of extra energy demand, while China, about 32% of fossil emissions, is expected to fall 0.9% even as coal rises 0.3%. The report estimates only 150 billion metric tons of carbon budget remain for limiting warming to 1.5°C, enough for less than four years at current rates. Land carbon sinks have recovered from the 2023-24 El Niño, but scientists expect the powerful 2026 El Niño to significantly affect absorption in the coming year. The research, led by Professor Pierre Friedlingstein of the University of Exeter, involved UEA, CICERO, LMU, the Alfred-Wegener-Institut and more than 90 other institutions. Friedlingstein said a reduction driven partly by geopolitical shocks is not a sustainable solution. Glen Peters of CICERO warned that one year of falling emissions is not a peak unless it reflects structural change, and Julia Pongratz of LMU said CO2 removal must be scaled up because deforestation still outweighs reforestation gains.
