Fossil CO2 emissions projected to fall in 2026: Report

Global carbon emissions from fossil fuels are projected to decline by 0.4pc in 2026, as renewable power capacity grows and conflict constrains oil supply, a team of scientists said today in the Global Carbon Budget 2026 report.

Global carbon emissions from fossil fuels are projected to stand at 38.2bn t this year, driven by a 1.9pc projected decline in carbon emissions from oil, the report found. This is "likely a short-term response to the energy shock triggered by the Iran conflict", it said. Carbon emissions from natural gas were projected to fall by 0.3pc this year, while those from coal are projected to rise by 0.6pc, the report found. Energy demand globally continues to increase, but two thirds of this is met by solar and wind power and electric vehicles (EV), the report said.

But although renewables and EVs "are increasingly offsetting growth in energy demand, further acceleration is needed if global emissions are to peak and enter a sustained decline", director of the university of Exeter's Global Carbon Budget Office Pierre Friedlingstein said.

"A drop in emissions in one year is not a peak unless it is driven by structural change", research professor at the Cicero Center for International Climate Research Glen Peters said.

Total carbon emissions — from fossil fuel consumption and emissions from land use change — are projected at 43.3bn t in 2026, up by 1.2pc on the year as CO2 emissions from land use change are projected to increase, the report said. Total CO2 emissions have in the past decade grown by 0.3pc per year on average, more slowly than the previous decade's 1.7pc annually.

The remaining carbon budget, which is the amount of CO2 that can be emitted before global warming reaches 1.5°C above pre-industrial levels, stands at 150bn t. This is equivalent to less than four years of emissions at current rates, the report found. The Paris climate agreement seeks to curb the rise in global temperature to "well below" 2°C above pre-industrial levels, and pursues a 1.5°C limit.

The Global Carbon Budget report is produced annually by an international team of more than 140 scientists.
