Iran war and renewables surge pause global fossil fuel emissions growth

A global flatline in fossil fuel emissions is emerging, driven by soaring oil prices from the conflict in Iran and a rapid uptake of electric vehicles, according to the Guardian ^[1]. The comprehensive assessment presented at Cop31 in Antalya predicts carbon dioxide from oil, gas, and coal will remain steady for 2026, with oil-specific emissions dropping by 2% as drivers economize.

Despite this milestone, the report’s authors warn that talk of a global turnaround is premature. The slight 0.4% reduction in fossil fuel emissions is statistically indistinguishable from zero, according to Bill Hare of Climate Analytics ^[1]. Total carbon emissions, including those from deforestation, are actually forecast to rise from 42.8 billion tonnes to 43.3 billion tonnes this year.

Data from the Global Carbon Project shows that two-thirds of the world's growing energy demand is now being met by solar and wind power, per ABC News (AU) ^[2]. Pierre Friedlingstein, lead researcher for the Global Carbon Budget Office, cautioned that clean energy growth is not yet fast enough to sustain this decline, noting that geopolitical shocks are not climate solutions.

China, the world’s largest emitter, is projected to cut its output by nearly 1% due to a 5% drop in oil use following the war ^[1]. The United States is also seeing a 1.3% decrease as coal use falls, despite former President Donald Trump’s push for fossil fuels. Meanwhile, India’s emissions are rising by 4.4% due to increased coal consumption.

The remaining "carbon budget" to keep warming below 1.5C is down to 150 billion tonnes, leaving less than four years at current rates, the Guardian reported ^[1]. Experts like Glen Peters of the Cicero Centre emphasize that without structural change, this drop is likely temporary. As Cop31 delegates debate policy, the data suggests that while the market is shifting, political will remains the critical missing piece.
