China, long the engine of global oil demand growth and the world’s largest crude importer, is undergoing a profound change. After decades in which its consumption more than doubled and accounted for a large share of worldwide demand increases, oil use—particularly for transportation fuels—has plateaued and, in key categories, begun to fall. Recent data point to genuine reductions driven by the rapid rise of electric vehicles, alternative fuels, public transport, and broader economic shifts, rather than temporary slowdowns alone.
Between 2005 and the early 2020s, China’s oil consumption expanded sharply as the economy industrialized and vehicle ownership soared. Transport fuels—gasoline, diesel, and jet fuel—formed a core part of that demand. By the mid-2020s, however, the picture changed. International Energy Agency analysis showed that demand for the main oil-based fuels reached a plateau, with combined consumption of gasoline, diesel, and jet fuel in 2024 only narrowly above 2019 levels and below peaks seen earlier in the decade.
Refined oil product consumption continued to ease. Gasoline and diesel use fell in successive years amid rising electric vehicle (EV) penetration and softer freight and construction activity. Jet fuel remained a relative bright spot thanks to recovering air travel, but it was not enough to offset declines elsewhere. State oil major Sinopec later assessed that overall oil demand very likely peaked in 2025, earlier than many prior forecasts that pointed toward the late 2020s or 2030.
In 2026, the trend accelerated under the pressure of higher prices linked to geopolitical disruptions. Oil consumption dropped notably in the second quarter (around 9% year-on-year overall, and more sharply in transport), contributing to a rare decline in China’s carbon dioxide emissions driven primarily by lower oil use rather than coal. Electric vehicles alone displaced tens of millions of tonnes of oil in the first half of the year—more than the United Kingdom’s total oil consumption over a comparable period.
The most powerful structural force has been the electrification of road transport. China has become the global leader in EV sales and fleet size. New-energy vehicles (battery electric and plug-in hybrids) have captured a large and growing share of passenger-car sales—frequently exceeding 50% in recent periods—and the overall EV stock has expanded rapidly. Charging volumes have surged, indicating higher utilization of the existing fleet as well as new additions.
This has directly displaced gasoline demand. Modeling and industry estimates attribute hundreds of thousands of barrels per day of avoided oil use to EVs, with the effect strengthening each year. Electric trucks and buses have added further pressure on diesel, while liquefied natural gas (LNG) trucks have provided another alternative for freight. High-speed rail expansion and growing use of subways, taxis (increasingly electric), and other public transport have reduced reliance on personal vehicles and conventional fuels even as overall mobility has remained resilient or continued to grow in many metrics.
These substitutions have already avoided substantial oil demand growth since 2019. Government policies supporting new-energy vehicles, charging infrastructure, energy security, and carbon goals (peaking emissions before 2030 and neutrality before 2060) have reinforced the shift. Domestic manufacturing strength in batteries and EVs has made the transition both strategic and economically competitive.
Beyond technology, China’s evolving economy has reduced the oil intensity of growth. A prolonged property-sector slowdown has curtailed construction activity, a traditional driver of diesel demand. Broader GDP growth has moderated from earlier double-digit rates and become less energy-intensive as services and high-tech manufacturing gain relative weight. Consumer behavior has also adjusted: higher fuel prices have encouraged shifts toward cheaper electric options, rideshares, or public transit.
While petrochemical feedstocks continue to support some overall oil demand growth, they have not fully offset the contraction in combustion fuels. Refinery runs and crude imports have reflected the weaker product demand, with China drawing on stockpiles and adjusting imports amid market conditions.
As the world’s largest oil importer, China’s reduced appetite has ripple effects. Lower import needs ease pressure on global supply balances and can moderate price spikes during disruptions. For producers and refiners focused on transport fuels, the shift poses challenges; demand growth is increasingly concentrated in petrochemicals and regions outside China. Emissions benefits are already visible, though the power sector’s continued reliance on coal means the overall climate picture remains complex.
Analysts differ on the precise timing and depth of the peak—some see total oil demand leveling off this decade with only marginal further growth, while others note that petrochemical needs and any rebound in activity could slow the decline. What is clear is that the era of China reliably driving large annual increases in global oil demand has ended. The combination of aggressive electrification, policy support, and economic maturation has produced a durable reduction in oil intensity that is reshaping both China’s energy profile and the international oil market.
