For the first time, more than half of all new cars sold in China in 2024 were electric or plug-in hybrid vehicles, a milestone that energy researchers have long identified as the point where a technology shift becomes self-sustaining. In Europe, a binding law now guarantees that every new car sold after 2035 must produce zero tailpipe emissions. Together, the world’s two largest auto markets outside the United States have crossed what analysts call a tipping point, and the consequences are rippling through the global car industry.
The International Energy Agency’s Global EV Outlook 2025, published in April 2025, confirmed that global electric car sales surpassed 17 million units in 2024, with China accounting for the majority. The China Association of Automobile Manufacturers reported that electric vehicles captured roughly 50% of new passenger car sales in the country that year, even as gasoline car purchases fell sharply. That simultaneous pattern, one technology surging while its predecessor contracts, is the textbook definition of a market inflection.
Why China’s shift looks permanent
Three forces are reinforcing each other in the Chinese market, making a reversal increasingly unlikely. Battery costs have dropped more than 60% over the past five years, according to IEA tracking, bringing the sticker price of many Chinese-made EVs below their gasoline equivalents. Manufacturers such as BYD, which overtook Volkswagen as the world’s largest automaker by revenue in late 2024, have waged aggressive price wars that compressed margins but expanded the buyer pool. And sustained government policy, including purchase tax exemptions and investment in charging networks, has kept demand climbing even as subsidies in other countries have been pulled back.
The result is a feedback loop that researchers at Bloomberg NEF have described in their tipping-point framework: once EV market share passes roughly 5%, adoption tends to accelerate rather than plateau, because each wave of buyers drives down per-unit manufacturing costs and expands the charging and service ecosystem for the next wave. China blew past that 5% threshold years ago. At 50%, the question is no longer whether EVs will dominate the Chinese market but how quickly gasoline models will be pushed to the margins.
Europe’s regulatory lock-in
Europe’s path runs through law rather than pure market momentum. Regulation (EU) 2023/851, published in the Official Journal of the European Union, amended the bloc’s CO2 standards for passenger cars and light commercial vehicles. It sets a binding 100% CO2 reduction target for new cars by 2035, effectively mandating that every vehicle sold after that date must be zero-emission. Interim targets for 2025 and 2030 create stepping stones that force automakers to increase their electric lineups well before the final deadline.
The European Environment Agency’s monitoring data already shows the regulation working as designed. As zero-emission vehicle registrations have climbed, average fleet-wide CO2 emissions have declined, connecting what consumers buy to measurable atmospheric outcomes. For automakers, the math is straightforward: any company that fails to meet the targets faces financial penalties, making continued investment in new gasoline platforms a losing bet.
The slowdown that wasn’t a reversal
Europe’s trajectory has not been smooth. The IEA’s 2025 trends analysis documented a slowdown in European EV sales after several member states rolled back purchase incentives. Germany’s decision to abruptly end its EV subsidy program in December 2023 was the single largest blow, removing up to 4,500 euros in buyer support overnight and triggering a sales dip that dragged down continent-wide figures.
But a temporary sales dip is not the same as a trend reversal. The EU’s legal architecture remains intact, and the 2025 interim CO2 targets are now in effect, meaning automakers face immediate compliance pressure to sell more zero-emission vehicles this year. Several manufacturers, including Stellantis and Volkswagen, have announced accelerated EV launch schedules for 2025 and 2026 specifically to meet these benchmarks. The subsidy withdrawal slowed the pace; it did not change the direction.
What this means for the rest of the world
The combined weight of China’s market dominance and Europe’s legal mandate is reshaping decisions far beyond those two regions. Global automakers design vehicles for their largest markets first. When the two biggest markets outside the U.S. both demand electric models, the economics of developing new gasoline platforms become harder to justify anywhere. Ford, General Motors, and Toyota have all adjusted their electrification timelines in the past 18 months, citing competitive pressure from Chinese manufacturers and European regulatory requirements.
The United States remains a conspicuous outlier. EV adoption has grown but sits well below Chinese and European levels, and the political environment around EV policy has been volatile. Still, American consumers are not insulated from global manufacturing trends. As automakers shift production toward electric models to serve China and Europe, the variety and competitiveness of EVs available in U.S. showrooms is increasing regardless of domestic policy signals.
The impact on global oil demand is harder to pin down with precision. The IEA and other agencies have not published granular estimates tying these specific sales milestones to barrels of reduced petroleum consumption. But the directional logic is difficult to dispute: when the world’s largest new-car markets stop buying gasoline vehicles, gasoline demand eventually follows. How quickly, and what that means for oil-dependent economies, remains an open question that the data has not yet answered.
Where the evidence stands as of mid-2026
The strongest evidence in this story is transactional. CAAM’s sales figures reflect what millions of Chinese consumers actually purchased, and those numbers show EVs commanding half the market. The EU’s legal texts are enacted law with enforcement mechanisms and compliance deadlines, not aspirational targets. The European Environment Agency’s emissions monitoring confirms that rising EV registrations are producing real-world pollution reductions, closing the gap between sales trends and environmental outcomes.
The IEA’s projections and trend analyses occupy a middle tier. The agency’s methodology is rigorous and its track record strong, but any forward-looking estimate depends on assumptions about battery prices, consumer behavior, and the durability of policy support. Europe’s near-term sales trajectory, in particular, will depend on factors still in flux: the pace of charging infrastructure expansion, the arrival of more affordable EV models from European and Chinese manufacturers, and whether additional member states restore or expand purchase incentives.
What can be said with confidence is narrow but significant. China’s auto market has crossed an inflection point from which a return to gasoline dominance is economically implausible. Europe has locked in a legal pathway that makes such a return legally impossible by 2035. The pace of the transition, its ripple effects on oil markets, and the exact shape of the next few years remain genuinely uncertain. But the direction is not.
