Question:

I have a 1999 Suburban which I got primarily to take 6 grandchildren on vacations. They are now busy with summer jobs and sports teams, and so the Suburban no longer has that function. A smaller car would serve my wife and me quite well.

Although I am a skeptic about anthropogenic global warming and its dangers, suppose I were not. If I were concerned about nothing but my automobile carbon footprint, would it be greater if I kept my Suburban for another 10 years or if I scrapped it now (in a way that no one else could use it) and substituted its carbon footprint for that of a smaller car, which would have to include the carbon footprint of its entire manufacturing process.
