Receiving great applause from climate advocates, Paris officials announced a new goal on Thursday to ban gas-powered cars from its streets by 2030.

The proposal would accelerate existing efforts to reduce air pollution in the city after French President Emmanuel Macron promised to ban the sale of vehicles with combustion engines by 2040.

Under the rule, only electric cars would be allowed in the city. Paris is already home to an electric car-sharing service, Autolib, which has become wildly popular since its launch in 2011 with the goal of reducing carbon emissions by 20 percent over a decade.

“Time is simply pressing,” said Christophe Nadjovski, Paris’s deputy mayor of transport, in an interview with the radio station France Info. “This is about planning for the long term with a strategy that will reduce greenhouse gases. Transport is one of the main greenhouse gas producers…so we are planning an exit from combustion engine vehicles, or fossil-energy vehicles.”
