Following its launch of a judicial challenge against Mayor Ken Livingstone’s emissions related congestion charge, Porsche today releases an examination of the expected CO2 savings.  Using Transport for London’s own figures, the savings expected in an entire year from the emissions charge will be equal to the emissions from Heathrow between 4 minutes and at most 4 hours.

Commenting on the figures, Andy Goss, Managing Director of Porsche Cars GB, said, “Under closer examination these figures show the negligible environmental benefits of this tax.  The emissions saved are a fraction of the amount of the CO2 pumped out every day at Heathrow.  Calling this tax an emissions charge is a misnomer.  Not only is this new charge an unfair tax on motorists and families, it is a tax that will do nothing to reduce emissions or congestion in London.”

The release of this examination comes two days after Porsche announced that it is seeking to make an application for judicial review of the proposed extension in the congestion charge, which will see the cost of driving some cars in the capital rise from £8.00 a day, or just 80p if they are residents in the congestion zone, to £25.00 a day - an increase of over 3000 per cent.  Porsche is seeking a reverse of this action based on the disproportionate nature of the charge.

Porsche also announces today that it has opened a website 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.  The website is available at

C-charge tax won’t reduce CO2 emissions Factsheet

The Mayor Ken Livingstone’s new £25 charge on larger cars will have practically no effect on the environment and looks more like an attempt to get additional revenue out of Londoners.  The CO2 saved in the first year of this scheme could be as little as 4 minutes of emissions from Heathrow Airport.

What this means for the environment
CO2 Emissions at Heathrow (Tonnes) CO2 Savings from the Low Estimate for the C-Charge (Tonnes) CO2 Savings from the High Estimate for the C-Charge (Tonnes)
Year at Heathrow 13,900,000 C-charge savings per annum 100 C-charge savings per annum 5000
Day at Heathrow 38082.19 How this compares:
Hour at Heathrow 1586.76 For the low band: (C-Charge savings per annum/CO2 per min at Heathrow) = 3.78 minutes
Minute at Heathrow 26.45 For the high band: (C-Charge savings per annum/CO2 per hour at Heathrow) = 3hrs 15 mins
