Sales of electric and hybrid cars in Norway outpaced those running on fossil fuels last year, cementing the country’s position as a global leader in the push to restrict vehicle emissions.

Norway, a major oil exporter, would seem an unlikely champion of newer, cleaner-running vehicles. But the country offers generous incentives that make electric cars cheaper to buy, and provides additional benefits once the vehicles are on the road.

Countries around the world have ramped up their promotion of hybrid and electric cars. As China tries to improve air quality and dominate new vehicle technology, the government there wants one in five cars sold to run on alternative fuels by 2025. France and Britain plan to end the sale of gasoline- and diesel-powered cars by 2040.

Norway is ahead of the rest of the world. About 52 percent of the new cars sold in the country last year ran on new forms of fuel, according the data released on Thursday by Norway’s Road Traffic Advisory Board, OFV. The share of diesel cars, which were once considered more environmentally friendly but are now in the spotlight for their noxious emissions, fell sharply.
