Live in the UK and want to know when is the best time to plug in your electric car? Or compare the true emissions figures for EV marques with conventional cars? Then visit Mike Boxwell's Owning An Electric Car website. I've just been there and here are the results:
Based on the carbon footprint right now (as I am writing this blog piece), this is how electric car emissions compare to those of conventional cars:
REVA L-ion | 50g/km |
Mitsubishi iMiEV | 55 g/km |
REVA i | 61 g/km |
MINI e | 67 g/km |
Nissan LEAF | 84 g/km |
Toyota Prius | 107 (89)g/km* |
Fiat 500 TwinAir | 114 (95)g/km* |
Ford Fiesta ECOtec | 118 (98)g/km* |
VW Polo Bluemtn | 119 (99)g/km* |
Honda Insight | 122 (101)g/km* |
MINI Cooper D | 125 (104)g/km* |
Fiat Panda ECO | 143 (119)g/km* |
BMW 116i | 172 (143)g/km* |
Ford Focus 1.6i | 189 (157)g/km* |
Average new car in the UK | 196 (163)g/km* |
Dodge Journey | 252 (209)g/km* |
*The figures in brackets show the 'Tank-to-wheel' figures for fuel used in a conventional car. These are the figures published by the motor manufacturers to show the carbon impact of driving their vehicles. The main figures show 'well-to-wheel' figures (including oil extraction, refining and transportation), giving a more accurate comparison to the full 'well to wheel' figures for an electric car.
Mike's calculations take into account the generation of electricity at the power station AND the carbon footprint for extracting and transporting the raw materials to the power stations AND the generation losses between the power station and your electric car AND an amount for decommissioning.
Brilliant!
PS Did you notice that there are large differences between electric cars? In the example above, the Nissan Leaf is emitting 50% more CO2 / km than the Mitsubishi imiev. Wait until the marketing guys catch up with this one!
