I’m curious how the calculations work here. I know that any individual battery electric car is better in terms of GHG emissions than any individual hybrid car. However, given the limited number of battery electric cars, and the limited production, battery electric cars will remain the minority of all cars at least until the end of this decade (probably even longer). Now my question is, en masse, since the production of hybrid cars are a lot more capable then battery electric, are we not better off (in terms of total GHG emissions) with as many hybrid cars as we could get? That is, don’t hybrid cars shave more GHG emissions just by the shear number of them?

Of course I believe this is a moot question because we could save way more by focusing on public transit, and simply have fewer cars. After all: battery electric are more efficient than hydrogen, which are more efficient then hybrids, which are more efficient than ICE but transporting 20 people in 15 battery electric cars comes nowhere close to the efficiency of transporting these same 20 people in a single ICE bus.
