Clean Tech Must Accelerate to Peak Global Emissions, Global Carbon Budget 2026 Warns

The 2026 Global Carbon Budget, published in Nature Climate Change, projects global fossil CO2 emissions will dip 0.4% this year to 38.2 billion tonnes, helped by solar, wind, and electric vehicles. The study warns that pace is not enough. Renewables and EVs are offsetting an estimated 64-79% of demand-driven emissions growth through 2028, but deployment needs to accelerate further to guarantee a peak and then a sustained decline. India stands out: emissions are projected to rise 4.4% in 2026, above the 3.5% average over the past decade. China's emissions are expected to fall 0.9%. The remaining carbon budget for 1.5 degrees Celsius is put at 150 billion tonnes, less than four years at current rates. The authors stress that a dip caused partly by the Iran conflict is not a durable climate solution.
