The data analysed on the slide below was taken from an article shared by the BBC under the heading “Electric car emissions myth ‘busted'”, from back in March…

The myth that apparently was being busted, was that more CO2 is emitted building an EV than a conventional car. The problem is that the article they reference makes it clear that more CO2 IS emitted.

Quite how much depends on a number of factors. Brand new, undriven, a comparable ICE car will be responsible for less CO2 and it’s only at some point in the future that tail-pipe emissions will be sufficient to swing the balance in favour of the EV. In the example cited in the article (which compared a Peugeot 308 1.6TD with a 30kWh Nissan Leaf), this cross-over point appears to be midway between 4 and 5 years.

Reduce the mileage, the recorded CO2 for the ICE car or increase the size of the battery and that break even point comes later.

Interestingly, the report authors go on to make this statement “Incorporating electric vehicle life-cycle manufacturing emissions into vehicle regulations would be misguided”. Hmmmm.

This is one of the slides we’ll be discussing at 10am tomorrow in our webinar.
