(NATIONAL REVIEW) Today is Earth Day. President Obama will mark the day by flying from Washington, D.C. to Washington state — 2,328 miles, generating 568,032 pounds of carbon emissions at 244 pounds per mile — and then beginning his week-long trip to Asia, flying tonight to Tokyo —  4,792 miles, an additional 1,169,248 pounds of carbon emissions.

The two trips add up to 1.73 million pounds of carbon or 868.64 tons.

For perspective, the average American generates about 19 tons of carbon dioxide in one year.
