Renewables curb CO₂ emissions, but they are not enough to ensure their reduction

The expansion of solar, wind and electric vehicles will offset much of the increase in energy demand by 2026. However, the emissions margin available to limit global warming to 1.5°C is already equivalent to less than four years of emissions at the current rate.

Global carbon dioxide (CO₂) emissions from fossil fuels could fall by 0.4% in 2026 to 38.2 billion tonnes, according to new estimates from the Global Carbon Budget, prepared by the Global Carbon Project. The advance of renewable energies and electric vehicles is helping to contain them, although part of the expected decline is also due to the energy crisis triggered by the conflict in Iran. The decline would be particularly pronounced in oil, whose emissions could fall by 1.9%. Those of natural gas would fall by 0.3%, while those of coal would increase by 0.6%. Although global energy demand continues to grow, approximately two-thirds of that increase is being covered by the expansion of solar and wind power and electric vehicles.
