How electric vehicles tackle the climate crisis

There have been the usual articles funded by fossil fuels spruikers that EVs don't reduce emissions compared to petrol/diesel cars.  Only trouble is, they do.  CarbonBrief has done a longish article about it, which if you have time you should read.  I'm putting just this chart up, because it's so revealing.

One can see that in all cases "pure"  ICEVs produce more emissions over their lifecycle than EVs.  However, the carbon cost of manufacturing is roughly the same for all cars (more for bigger, obviously).  That will only change when we start producing iron and steel using green methane/hydrogen.  If we compare the non-battery manufacturing emissions over a car's lifecycle, the ratio of emissions by EVs compared to ICEV's is much lower.  In France the non-manufacturing emissions of the Nissan Leaf compared to the non-manufacturing emissions of an average Euro petrol/diesel car are 80% lower--because most of France's electricity comes from nuclear power.  Even in Germany, where a lot of electricity is generated by massively polluting brown coal (lignite) power stations, the non-manufacturing emissions by EVs compared to ICEVs is 30% lower.  As more and more electricity is generated by renewables, these ratios will fall further.  But no matter how green the grid gets, petrol cars will always produce 212 grams of CO2 per kilometre.

Moral of the story: EVs produce fewer greenhouse gasses and will produce fewer still when batteries and steel are made using green electricity and methane.
