This is a very good analysis, however I think a few more issues should be also considered. The lifetime assumption of 10 years is good for new cars, but for older cars, depending on the age when bought the lithium ion batteries may be need to be replaced within that time, incurring the batteries manufacture hit once again. The other issue is that cost is not considered and the analysis assumes a single car. Right now a small percentage of cars is electric, but if even half of all new cars were electric then until the battery/electric motor mineral supply chain ramps up the cost of electric vehicles will go up significantly. If the goal is to reduce emissions from the current level, using batteries in hybrid vehicles ( which use a much smaller number of batteries than a full BEV) would reduce emission even more since many more of them could be produced for the same amount of money. For example replacing 50% of all existing cars with hybrids that get double the mileage of current cars would reduce the emissions by 25% the same as replacing only 25% of existing cars with fully electric ones. The problems of upgrading grids and adding charging stations is also a hidden cost, since, like it or not, the petroleum infrastructure is already fully built out.

Always thought EVs are better on a long term basis but a 2-3 years (in case of UK) payback on production emissions is awesome.
