Virgin jet testing biofuel

This is the first I've heard of an airline trying biofuel: Virgin jet to use biofuel blend in test flight in February from London to Amsterdam.

Airline industry officials, environmentalists and energy companies all have a huge interest in the future of air travel as it pertains to fuel consumption, carbon emissions and global warming.

From the business perspective, the airlines are under great financial pressure because of soaring fuel costs; the price of crude oil is consistently flirting with $100 per barrel. On the environmental side of things, aircraft represent up to 12 percent of greenhouse gas emissions produced by the U.S. transportation sector, according to the Environmental Protection Agency.
