Tony Juniper, Friends of the Earth executive director, has slated Porsche for fighting against the increase in congestion charge (CC).

Juniper said the luxury car marque ‘has a vested interest in keeping polluting vehicles on the road.”

Porsche announced earlier this month it was seeking a judicial review of Transport for London’s increase for the congestion charge to £25 for vehicles that emit over 225g/km CO2.

Juniper added that there was a lot of resistence from big brands against the CC increase.

He said: “Marketing can be powerful in promoting cultural change in the mind of the consumers but it can’t be done as an add on. But we need to change big business first and that can’t be done purely through communications.”

Porsche believes that rather than picking on its motorists, the Mayor of London should be looking to the skies.

It used Transport for London’s own figures to calculate the savings expected in an entire year from the emissions charge. Porsche believes the amount of CO2 saved would equal to the emissions from Heathrow airport between four minutes and at most four hours.

Porsche is seeking a reverse of the CC rise based on the "disproportionate nature of the charge".

Porsche has launched www.porschejudicialreview.co.uk for the legal case where families and motorists across London who will be impacted by the new tax can get more information and add their name to a petition against the charge.
