http://www.washingtonpost.com/world...and-from-paris/2011/06/22/AGfpLVfH_story.html Dutch airline KLM plans to use recycled cooking oil as biofuel to power flights to and from France in a move aimed at cutting carbon emissions. Starting in September, KLM will begin more than 200 flights between Paris and Amsterdam using biofuel made from used cooking oil, the company said Wednesday. KLM managing director Camiel Eurlings said in a statement the airline does not have to make any changes to its aircraft engines to use the new biofuel. The biofuel flights are intended to help reduce KLM’s carbon emissions while having a “minimum negative impact on biodiversity and food supply.” Air travel is responsible for about 3 percent of greenhouse gases, but their share of global emissions is rising rapidly. The European Union told airlines earlier this year they would have to cut their carbon emissions by three percent on flights to the continent in 2012 to fall within new pollution limits.
