If I were going to the inauguration

This is what my carbon footprint would look like with

1. An economy flight from Hartford to National,
2. Public transportation from National to my hotel,
3. Two nights for two people in a DC hotel, and
   
4. Attending the inauguration.

0.278 metric tonnes. Think about that. If I'm normal¹ and if 2 million people really show up from out of town, that's about 550,000 metric tonnes of CO₂ associated with the Obama inauguration. To put that in perspective, the entire country of Bermuda was responsible for about 550,000 metric tonnes of CO₂ emissions in 2007 (Wikipedia).
