China’s Electric Trucks Are Breaking The Diesel Assumptions In Oil Forecasts

China is pushing hard to electrify its heavy trucks, and the numbers are big enough to change global oil forecasts. The country's plan aims for 40% of new heavy-truck sales to be electric by 2030, with more than 1.6 million electric trucks on the road, about 20% of the national fleet. Those trucks are meant to carry 18% of all highway freight, concentrated in ports, mines, steel mills and other operations that log heavy mileage. China is also building about 30,000 kilometers of dedicated freight corridors and roughly 3,000 truck charging and battery-swapping stations to support them.

This matters because trucks burn far more fuel per vehicle than cars, so electrifying even a fifth of the fleet can cut a large share of diesel demand. Electric heavy-truck sales already hit about a quarter of new sales in early 2025. One rough estimate puts the potential diesel displacement at several hundred thousand barrels a day by 2030, on top of separate gains from LNG trucks and electric cars. The International Energy Agency now expects China's oil demand to peak this decade, a shift from years of assuming steady Chinese growth. China's crude imports still look strong, partly because of stockpiling and discounted purchases, not because road fuel demand is rising.

None of this changes anything for your own home directly. It is a sign that global energy markets, including oil, are shifting faster than expected as electrification spreads beyond passenger cars into heavy industry and freight.
