This is a big plus for me. I do a lot of short journeys so my current ICE will be emitting far more CO2 than the book figure, all past houses and local shops etc. Very much looking forward to not having tailpipe emissions again!
Before the "but the grid still emits CO2" brigade comes in:
- Average car in the UK emits 160gCO2/km.
- Average grid emissions is 220g/kWh
- Average EV economy is 5.44km/kWh
...so 220/5.44 is 40gCO2/km for EVs, on average. If the grid is a lot cleaner, such as the current forecast of 82g/kWh on Saturday, that comes down to 15gCO2/km, less than a tenth of the emissions of an average ICE car.
As you can imagine, this figure actually becomes even more exaggerated comparing town driving, where ICE will be less efficient (pumping out more CO2) and EVs shine - I regularly saw over 4.5mi/kWh (sometimes even over 5) when my driving was focussed around town. Use that figure, and an average grid day means CO2 emissions of 30gCO2/km, or just over 11gCO2/km on a better grid day.
