He also was involved in creating Mobil 1 synthetic oil, which is one of the better synthetic motor oils out there.

You could make the argument that better motor oil allows cars to stay on the road longer, reducing demand for energy/materials to make new cars, or increasing the number of affordable, reliable used cars for less wealthy (or more frugal) people to drive. Plus, some improved fuel economy (due to engine being in better repair longer), so less CO2 emissions.
