TOKYO — Toyota, under ambitious environmental targets, is aiming to sell hardly any regular gasoline vehicles by 2050, only hybrids and fuel cells, to radically reduce emissions.

The automaker promised to involve governments, affiliated companies and other “stakeholders” in its push to reduce average emissions from Toyota cars by 90 percent by about 2050, compared with 2010 levels.

Electric cars weren’t part of their vision, outlined by top Toyota officials at a Tokyo museum today, striking a contrast with rivals such as Nissan, which has banked on that zero-emissions technology.

Toyota’s commitments come at a time when the auto industry has been shaken by a scandal at Germany’s Volkswagen, in which it admitted it cheated on diesel emissions tests covering millions of cars.

Toyota projected its annual sales of fuel cell vehicles will reach more than 30,000 by about 2020, which is 10 times its projected figure for 2017.

Fuel cells run on hydrogen and are zero-emissions. Toyota’s Mirai fuel cell went on sale last year. Toyota has received 1,500 orders for the Mirai in Japan, and it just went on sale in the U.S. and Europe.

Annual sales of hybrid vehicles will reach 1.5 million and by 2020 Toyota would have sold 15 million hybrids, nearly twice what it has sold so far around the world, it said.

Hybrids switch between a gasoline engine and an electric motor to deliver an efficient ride.

The Toyota Prius, which went on sale in 1997, is the top-selling hybrid, with about 4 million sold globally so far. Toyota is promising to develop a hybrid version in every category.
