The sale of gasoline- and diesel-powered cars in Germany may end up being prohibited as early as 2030, if guidelines set out in a resolution passed by the German upper house are adopted.

The resolution, though non-binding, also urges the European Commission to implement the ban across the European Union, as well as “review the current practices of taxation and dues with regard to a stimulation of emission-free mobility.” The latter is widely considered to be in regards to current subsidies placed on diesel fuel in Europe; and possibly about eliminating the subsidies or even increasing taxes on diesel, along with gasoline, to promote zero-emission vehicles.

The German resolution follows similar proposals from other European nations such as Norway and the Netherlands, but with Germany being the automotive hub of Europe it’s a strong statement signaling where the road might be headed when it comes to internal combustion cars.

Interestingly, it also comes at a time when the three major German automakers are doubling down on electric car developments. And in April, Germany also introduced a 4,000 euro (approximately $4,480) incentive program for electric cars.

While such proposals would only affect sales of new cars, worryingly some countries have started to introduce bans on existing cars. France for example has banned older cars from entering Paris’ city center during the week.
