China's emissions fall as Iran war cuts oil

Carbon dioxide emissions from the People's Republic fell by 1% after the outbreak of the US-Israeli war on Iran. The drop was driven by a sharp reduction in oil consumption and a steady rise in the use of electric vehicles and public transport, according to an analysis for Carbon Brief by the Centre for Research on Energy and Clean Air.

The report reveals how clean energy helped cushion the world's biggest oil importer from price shocks caused by the Strait of Hormuz crisis. It reinforces hopes that the world's largest greenhouse gas emitter may be nearing a turning point in decarbonising its economy.

The nation increased overall transportation use while cutting oil imports by 32% in the second quarter. This reduction, equivalent to about one million barrels per day, helped stabilise global oil prices, which had surged by about 60% after the first US airstrikes in late February.

Analysing the import drop

Speculation has surrounded how the country achieved this. The analysis indicates about two-thirds of the fall in imports came from drawing down strategic oil stockpiles rather than building them up. The remaining third was largely covered by a reduction in demand.

Overall oil use fell by 9%. Demand for transport oil fell by 16%. While many petrol and diesel vehicles stayed off the roads, journeys by electric cars, buses, trains, and trucks surged.

This electrifying trend began long before the crisis. The world's biggest manufacturer, user, and exporter of batteries, electric vehicles, wind turbines, and solar panels saw the disruption of Gulf oil supplies strengthen the economic and strategic imperative to reduce petroleum dependence.

In the first half of 2026, the shift towards electric vehicles displaced oil equivalent to the United Kingdom's entire six-month consumption.

A structural shift in transport

Analysts predict much of this oil demand will not return even if global prices fall. Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air, linked the change to policy.

In a qualitative sense, there's no question that the transport sector decarbonisation has been accelerated, Myllyvirta said. It's a validation of the energy security strategy that the nation has in place.

Myllyvirta noted this was the first time overall emissions fell due to reduced oil use rather than lower coal consumption.

Coal and the longer-term trend

Coal generation actually rose during the quarter. Shifting economic incentives and grid adaptation delays caused considerable wastage of wind and solar power. Despite this, observers believe the longer-term trend is away from fossil fuels.

Dr. Muyi Yang, a senior analyst at Ember, said a fossil fuel peak is coming into view at provincial and sectoral levels. The think tank will publish a separate overview of the country's energy trends next week.

The Iran crisis reinforces the case, Yang said. The way the nation has been able to absorb its impact strengthens the confidence to go deeper and further.
