This is based on your information above. I am comparing to similar sized cars, hence why I chose the Zoe and Yaris
Then you also need to include the mining of the raw materials for the batteries. Whilst we are at it, why not include the raw materials for tyres, the chassis, the suspension, any hydraulic fluid?
Again, these figures are probably available. But then why not include the CO2 from the coal/oil/gas mine/well to the power plant for EVs. And then what about the actual impact of mining these raw materials, since you are being so pedantic? Because coal mining and cobalt/lithium mining probably have a greater impact on the environment, from a producing perspective, than oil
