How am I doing on my New Years resolution to increase my carbon footprint?

So far I have let my truck run for at least a half hour before and after work (sometimes at lunch without leaving the office so it doesn't get too cold), I let the shower warm up for a good 10 minutes before getting in, and I heat my house to a constant 85 degrees. But since the temperature here hasn't gotten above 20 degrees for over 2 weeks, I feel I'm not doing enough. Am I doing a good job? What else can I do?
