Nothing but Green Skies If You Fly These Airlines
This doesn't get us off the hook for flying less, however.

What’s in a jet fuel? If you’re flying on one of these environmentally friendly airliners, vegetable oil, desert plants, or some other biofuel concoction could be powering the engines.
According to the Natural Resources Defense Council, more than 40 commercial airlines have flown around 600,000 miles powered at least partly by biofuels. That may not make much of a dent yet in the 640 million metric tons of carbon pollution emitted by the airline industry annually, but it’s a start.
Now, for the first time, NRDC has ranked the commercial airline companies working the hardest to reduce their carbon footprint with the use of sustainable biofuels.
The early leaders include Air France/KLM, British Airways, United Airlines, Virgin Atlantic, Cathay Pacific, and Alaska Airlines.

More than 200 million years ago, a cataclysmic event known as the Permian extinction destroyed more than 90% of all species and nearly 97% of all living things. Its origins have long been a puzzle for paleontologists, and during the 1990s and the early part of this century a great battle was fought between those who thought that death had come from above and those who thought something more complicated was at work.
Paleontologist Peter D. Ward, fresh from helping prove that an asteroid had killed the dinosaurs, turned to the Permian problem, and he has come to a stunning conclusion. In his investigations of the fates of several groups of mollusks during those extinctions and others, he discovered that the near-total devastation at the end of the Permian was caused by rising levels of carbon dioxide leading to climate change. But it's not the heat (nor the humidity) that's directly responsible for the extinctions, and the story of the discovery of what is responsible makes for an fascinating, globe-spanning adventure.
Well, all of us who can afford gas masks and whole house hydrogen sulfide air scrubbers.
