I was doing a little research, and while definitive data was hard to find I found some statistics that stated that over its lifetime a gas car produces 24 tons of CO2, while an EV produces 19 tons of CO2 (taking manufacturing into account, etc.). I realize that those numbers could vary wildly by location, etc., but are they even remotely in the ballpark? At a cost of $10 per ton of carbon offset, that implies that the cost to offset buying a gas car vs. EV is $50. That doesn't sound right.
