We've posted before about how we've been driving less, but we finally figured out how much less we've been driving. We buy gas for our car once every three weeks. Since we arrived here in February, we've driven only about 3,300 miles and are on pace for 4,500 miles for the 12 month period after arriving here.

When we lived in Texas, we each had our own car and totalled around 17,000 miles over the previous year. That means we're driving about 1/4 as many miles as we used to. Even if you factor in our drive up here from Texas, that's only about 7,000 miles on our car for a full year.

Excluding our drive up here, our reduction in driving has prevented roughly 9,000 pounds of carbon dioxide from being released into the air. The amount of CO₂ emissions we saved is equivalent to the amount produced by an average home's electricity use in over half a year. It's nice to do our part to help the environment.
