With the axe being taken to the country’s spending, it’s no surprise that the coalition government is reversing on the promises of its predecessor to underpin the electric car industry with grants and tax breaks.

The huge investment in electric tech has been spurred by the great CO2 panic. And electric cars don’t emit CO2, do they? Well, not locally. But that’s not strictly relevant because CO2 is not locally harmful.

Research carried out by BMW and the Technical University of Munich suggests that where in Europe you recharge your electric car makes a huge difference to its overall CO2 emissions, depending on how the electricity is generated.

Recharge in hydroelectric-intensive Norway and the CO2 emitted when fully charging a battery is nearly zero. Charge up in nuclear power-friendly France and the CO2 is between 35 and 50g/km; charge via a coal-fired power station and the CO2 equivalent is around 130g/km.
