If you stipulate no significant co2 emissions, then you can't have nuclear, either.

Let's say we want to build 100 new nuclear reactors (this would double what the US currently has). It takes about 200,000 tons of concrete to build one reactor. Concrete production outputs about 900kg of co2 per ton.

Cars output 1.5B tons of co2 per year. For the co2 cost of building 100 nuclear plants, we could continue driving ICE cars for an additional 12 years.

This doesn't even take into account steel production, which also has significant co2 output.
