The ban would only apply to vehicles registered after 2019.

The war on diesel continues, with the latest battle taking place in the capital of Denmark. Copenhagen mayor Frank Jensen wants to ban all new diesel-powered cars from entering some parts of the city in just a few short years.

The new law comes in response to a study which claims diesel car ownership is higher than average in Copenhagen than in the rest of Denmark. 68,141 of the 168,039 private vehicles registered in Copenhagen are diesel-powered, according to the Copenhagen Post.

Jensen's office points out about 80 people die annually as a result of pollution, and roughly 20 of those are linked to car emissions. The source of the statistics hasn't been provided.

The ban -- which is part of Jensen's reelection campaign -- would come into effect on January 1st, 2019. It would only apply to cars registered after that date; motorists would be able to drive a 1987 BMW 324td downtown but not a 2019 BMW 320d equipped with modern emissions control software and hardware.

"The proposal will have an effect, because there will not be any new diesel cars after 2019 and we will also be able to reach those who are going to make the choice between a diesel car and a less-polluting petrol-engined car," explained Jensen, according to the Copenhagen Post.

Jensen is also targeting wood stoves, and the massive cruise ships which dock in Copenhagen's harbor and idle on bunker fluid for days on end. He also promises to replace diesel-powered buses with electric ones.
