A heavy weight battle looks to be shaping up in the UK, over the capital’s increased congestion charge proposal. Appropriately in the red corner will be Mayor of London Ken Livingston. In the blue corner will be German car giant Porsche who says it will take the matter to court if the Mayor does not amend his proposed changes.

Livingston recently announced that all cars that emit more than 225g of CO2 per km will be charged £25 to enter London every day, a rise from the previous charge of £8. This has caused alarm at Porsche as all but one of its current range emit more than this limit and the bulk of its UK sales are made in London. The carmaker has said it will make an application for judicial review of the proposed changes, which it calls “unfair and disproportionate”.

The Mayors office spokesman responded saying “Porsche is trying to impose on all Londoners unnecessary levels of pollution and greenhouse gases by a tiny minority. No one is allowed to throw their rubbish in the street and Porsche should not be allowed to impose gas-guzzling polluting cars on Londoners who do not want them.”
