Ecometrica has published a paper which calculates CO2 emissions from electric cars, taking into account emissions at the electricity producing power station.
The paper finds that, based on a range of electric cars that you can buy in the UK this year and next the average emissions are 75 gCO2/km.
This figure is lower than any other car in production today, including the Toyota Prius (89 gCO2/km) and VW Golf Bluemotion (99 gCO2/km), two of the incumbent best performing low emission vehicles in the “small family” class of car.
For reference the government figure for CO2 emissions from an average UK car is 208 gCO2/km. If emissions from the power station were included in official gCO2/km figures electric cars would still qualify for exemption from the London Congestion Charge and UK road tax.
