Why do Leonardo DiCaprio and Richard Branson lecture us about carbon consumption while plotting trips to space?

If all goes according to plan, Hollywood icon Leonardo DiCaprio will blast into space aboard the maiden voyage of Richard Branson's Virgin Galactic spaceship sometime this year, opening up a new era of civilian space travel. This development might only be remarkable as the fulfillment of a dream long predicted by futurists and technophiles, were it not for the fact that Messrs. Branson and DiCaprio are prominent environmentalist celebrities who have warned of a coming ecological catastrophe if we fail to address our carbon problem.

Private space travel doesn't seem to mesh with living green, and Mr. Branson surely anticipated that his project would raise environmentalists' eyebrows. Perhaps that's why he announced this past May: "We have reduced the [carbon emission] cost of somebody going into space from something like two weeks of New York's electricity supply to less than the cost of an economy round-trip from Singapore to London."

 

That would be a remarkable achievement in energy efficiency if it were true. Alas, it is not. According to the U.S. Federal Aviation Administration's environmental assessment of the launch and re-entry of Virgin Galactic's spacecraft, one launch-land cycle emits about 30 tons of carbon dioxide, or about five tons per passenger. That is about five times the carbon footprint of a flight from Singapore to London.
