Beijing government will fundamentally eliminate days of heavy air pollution by 2025 through gradually banning diesel and promoting new energy vehicles, a draft for a guideline on the city’s next five-year plan said on Sunday.

The draft said that the capital will replace vehicles for public use powered by gasoline including buses, sanitation trucks, taxis, postal vehicles, vans and official cars into new energy and ban diesel cars in Dongcheng and Xicheng districts step by step within the next five years.

The government will encourage private gasoline car owners to change into new energy ones and speed up building more hydrogen fueling stations for new vehicles in the capital.
