Why is EV adoption so uneven across countries?
Policy targets, charging infrastructure, income levels and the strength of domestic car industries all pull EV adoption by country in different directions. Norway reached 95.4% in 2025 after years of tax exemptions, free parking and toll waivers that made electric cars cheaper to buy and run than petrol equivalents. Denmark gained 61.5 percentage points between 2020 and 2025, the largest jump of the 53 countries, reflecting a similar mix of incentives and high fuel taxes.
In the EU, Transport and Environment note that the bloc's car CO2 targets have been the main engine of growth, compelling manufacturers to accelerate sales and bring new affordable models to market.1 Countries without binding fleet targets, or with strong hybrid industries that offer a middle path, have moved more slowly. The 2020 baseline also matters: that was a pandemic year with unusually low total car sales, which mechanically lifted the battery-electric share in some markets more than others.
Why is EV adoption slow in the US and Japan?
Japan's 1.8% battery-electric share in 2025 reflects several structural factors specific to its market. The average daily travel distance in Japan is only 30 km, among the shortest in the world, which reduces the range advantage that battery-electric cars hold over alternatives.2 Japan also has one of the most developed public transport systems globally, with railway on-time rates of 99.9%, meaning many residents do not depend on a private car at all.2
Hybrid vehicles are a further reason. Toyota's Prius and similar models offer strong fuel economy without requiring charging infrastructure, and in a country where earthquakes and typhoons cause frequent power outages, the ability to refuel at a petrol station during an emergency is seen as a practical advantage over a battery-electric car.2 The United States reached 7.8% in 2025, held back partly by a less dense charging network outside major cities and a market historically oriented toward larger, longer-range vehicles. The chart counts battery-electric cars only; figures that include plug-in hybrids would be higher for both countries.
Who wins and who loses if the EU weakens its 2035 car rule?
Transport and Environment argue that weakening the EU's 2030 target, as proposed by the EPP/Salini proposal currently under discussion, would stall battery-electric cars at 22% of the EU market in 2030 instead of 47%, cut sales of models priced below 25,000 euros by nearly three quarters, and leave cumulative emissions to 2050 around 40% higher than under current law.1
Consumers who buy petrol or diesel cars would continue to bear fuel costs that have risen sharply: Transport and Environment calculate that home-charged electric cars cost 50% less to run than petrol and diesel cars as of Sep 14, 2026, and that the oil price shock since the Iran war began has cost EU road users 53 billion euros, with diesel accounting for 40 billion euros of that.1 Carmakers that have already invested in electric platforms stand to lose the scale that makes those investments profitable, while those that delayed electrification could gain time, though Transport and Environment say all European carmakers are expected to comply with the current 2025 to 2027 targets regardless.1
What do analysts say about EV growth slowing in Europe?
Transport and Environment see EU EV growth accelerating rather than slowing in 2026. The organisation reports that 1.64 million battery-electric cars were sold in the EU from January to August 2026, a 45% increase year on year, and that battery-electric cars outsold pure petrol cars for the first time over a full quarter in Q2 2026.1 The battery-electric share for January to August 2026 reached 22%, up 6 percentage points on the same period in 2025, with August alone hitting 28%.1
Transport and Environment attribute the surge primarily to the 2025 to 2027 EU car CO2 compliance cycle, which is pushing manufacturers to put more models on sale and cut prices. About 60 new battery-electric models are expected by the end of 2026, nearly four times the average of 15 new models per year between 2021 and 2025, with the number of affordable models priced below 25,000 euros set to double in 2026 alone.1 VW's sales chief is cited by Transport and Environment as attributing rising demand partly to high petrol and diesel prices, suggesting the oil price shock is adding a second push alongside the regulatory one.1 Italy, Slovenia and Bulgaria recorded strong volume growth in 2026, though all three remain in single digits for market share.1
