Depends a lot on the fuel used. Solid boosters are terrible. Kerosene, like on the Falcon not too bad, but not great. Methane is better, it can in theory be made carbon neutral. Hydrogen is the best because it only produces water, but it’s not great as a first stage.

Methane is a much stronger greenhouse gas than the amount of CO2 you get when you burn it. Most sources/uses of it are a net positive in terms of greenhouse effect.
