British Airways Pursues Biofuel

By 2014, British Airways could be powering its fleet with biofuel, reducing its carbon emissions by 145,000 tons per year. The airline recently announced a partnership with Washington, D.C-based Solena Group to build Europe's first low-carbon jet fuel plant in the U.K., which could result in a 50 percent reduction in BA's emissions by 2050.

This got us wondering: How are other airlines faring in their efforts to clean up an industry notorious for its high levels of pollution?

• According to a report card by Green America, Delta Airlines ranks No. 1 in recycling passenger waste, though it only earned a "B-" overall. Only about 20 percent of all airline waste is recycled, though 75 percent is recyclable.
• Airbus recently announced its intention to test biofuels when they are available. SeatGuru says that Air New Zealand, Continental, Japan Airlines, JetBlue, Lufthansa, and Virgin Atlantic are also testing the alternative fuel source.
• Within 50 years, the International Air Transport Association hopes to create an aircraft that is entirely carbon-neutral.

Tell us: Would you pay more to fly on a greener airline?
