The Royal Borough of Kensington and Chelsea has applied to join Porsche’s fight against the congestion charge.

Andy Goss, managing director of Porsche Cars GB, said: “I am pleased that Kensington and Chelsea has joined us in our fight against this unfair, counter-productive tax against motorists.

“It is becoming increasingly clear that Londoners are rejecting this unfair £25 charge that will likely make congestion and the environment worse than it is today.”

The news follows an unreleased report from Transport for London which showed that the £25 increase for the most polluting cars would actually increase carbon dioxide in the capital by 182,000 tonnes.

The report indicates that the increase is largely caused by increased car mileage outside of the congestion charging zone as a result of the new charge.

All figures previously publicly released by TfL with regard to the impact of the new charge on CO2 emissions related only to the position within the congestion charge zone. It has never released estimates taking into account the effect on the whole of Greater London.
