Fossil Fuel Emissions Dip 0.4% as COP31 Opens in Turkey 2026

Fossil fuel emissions are set to dip slightly in 2026, according to a comprehensive assessment presented at the COP31 climate talks in Antalya, Turkey. The report forecasts a 0.4% reduction in carbon dioxide from oil, gas, and coal compared with last year, marking a fragile pause in the long-term rise of greenhouse gases.

The findings, unveiled on Tuesday morning, attribute the drop to soaring oil and gas prices following the war in Iran, which have encouraged drivers to economise on fuel and switch to electric vehicles. Emissions from burning oil alone are projected to fall by 2%.

But the authors caution that talk of a global turnaround is premature. Increased emissions from deforestation and land use change, following major fires in south-east Asia and conversions of wild land to agriculture, more than offset the fossil fuel decline.

Why the Slight Drop Matters

The 0.4% decrease may seem small, but it signals that high fuel prices and the global expansion of cheap renewable energy—chiefly solar and wind—are beginning to bend the emissions curve. According to the report, oil emissions will drop as drivers flock to electric vehicles and economise on fuel use.

This is the first time in years that fossil fuel emissions have flatlined rather than risen. The assessment, based on data from the year so far, provides a comprehensive view of how energy markets and climate policy are interacting.

However, the reduction is fragile. Many factors could disrupt the trend, including an intensified expansion of coal in India, an easing of oil prices, and US president Donald Trump's enthusiasm for fossil fuels.

Key Findings from the COP31 Report

• Fossil fuel CO2 emissions are forecast to fall 0.4% in 2026 compared with 2025.
• Oil emissions alone will drop by 2% as drivers switch to electric vehicles and cut fuel use.
• Renewable energy expansion, especially solar and wind, is a major driver of the decline.
• Deforestation and land-use change emissions more than offset the fossil fuel reduction.
• Coal expansion in India and potential oil price drops could reverse the trend.

The Role of the Iran War and Renewable Energy

The war in Iran has pushed oil and gas prices higher, making fossil fuels more expensive for consumers. This price shock has encouraged economies to look beyond fossil fuels, accelerating the adoption of electric vehicles and renewable energy.

At the same time, the global expansion of cheap solar and wind power is reducing reliance on coal and gas for electricity. The report highlights that these two forces—high prices and cheap renewables—are working together to slow emissions growth.

Yet the authors warn that the drop could be temporary. If oil prices ease, drivers may return to petrol cars, and coal use could rise in countries like India where expansion is intensifying.

Comparing Emissions Trends

The table shows that while oil emissions fall, gas and coal remain flat, and land-use emissions rise. The net effect is a slight decrease in fossil fuel emissions, but a larger increase in total greenhouse gases when land use is included.

What to Watch Next

Analysts will be watching several factors that could alter the trajectory. An intensified expansion of coal in India could push emissions back up. A drop in oil prices could reduce the incentive to switch to electric vehicles. And policy shifts in the US, particularly under President Trump, could weaken federal climate action.

Much greater investment in renewable energy and low-carbon technologies is needed to turn the slight dip into a sustained decline. The report's authors emphasise that without such investment, the current trend could reverse quickly.

For those tracking the energy transition, the interplay between fossil fuel markets and clean energy costs will be critical. As carbon emissions from fossil fuels fall slightly as Iran war boosts prices, the question is whether this shift is durable or merely a blip.

The COP31 talks in Antalya will continue to focus on how nations can scale up renewables and reduce deforestation. The conference provides a platform for countries to share strategies and commit to stronger targets. The background to this story is set out in New Tool Reveals Fossil Fuel Emissions Damage Estimates. A related thread runs through Australia's COP31 Climate Talks Role Sparks Fossil Fuel Debate.

Remote work trends may also play a role in future emissions. As remote work and environment: Australia's green advantage shows, shifting commuting patterns can reduce transport emissions, complementing the drop in oil use. Earlier coverage in Australia and Turkey Criticized for Hosting COP31 Climate Talks shows how the argument developed. A closer look at the same subject appears in How to Tackle Data Centre Climate Impact and Carbon Emissions.

Ultimately, the slight fall in fossil fuel emissions is a sign that change is possible, but it is not yet a solution. The report makes clear that without sustained investment and policy support, the world remains far from a permanent decline.
