1) Global Warming (Climate change, w/e) DOES exist.
2) Ozone Depletion IS real.
3) We don't have the technology or the the resources (financial or otherwise) to put a quick end to extreme hydrocarbon usage. Hydrocarbons are important in almost everything, from fuels to plastics. Hydrocarbon chains are used in practically everything and are even release in flatulance.
4) We should increase domestic drilling. This will decrease our reliance on foreign, terrorist countries who likely are less green than we are in drilling.
5) The market will eventually demand (and currently this is starting to increase) more 'green' vehicles. You can already see the effects here. The capitalist way states that when there is a deman companies will try to create a supply. In this way we will slowly work toward green energies anyway. When 'green' energy becomes cheaper, and I believe it will at some point with the huge demand we have for fossil fuels, the demand for green energy will increase and companies will work toward increasing their supply.
So hows that coming from a, "you conservative"?
Oh and to add a fact, CO2 isn't the only problem with car emissions from gasoline and diesel engines. SOx and NOx also pose a significant problem (released from vehicles and factories). There are other contributors too, of course.
