carbon foot print cars

I'm very into cars so far I have owned 3 cars in my life.  A mustang gt which drank gas, a subaru impreza 2.5rs and now I drive an Acura RSX Type S.  The Acura is decent on gas even though its a sports car, I have a six speed manual and can get up to 31 on the highway.  I still go through 12.5 gallons of premium a week,  I also change my oil religiously at 3000 miles.  I believe I will go through cars rather quickly (I get bored and trade up) and will probably buy a car every 4 years minimum for the next 60 years.  Now here's how everything adds up, I will go through a minimum of 36,000 gallons of gas in my lifetime as well as 120 quarts of full synthetic oil (which I recycle). I will probably buy at least 15 more cars for myself at a minimum.
