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。 荷兰航空将用“地沟油”做燃料 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 2017 to fall within new pollution limits。 The limit is designed to encourage airlines to reduce greenhouse gases that contribute to global warming by switching to cleaner fuels or economizing on fuel consumption with lighter aircraft or more efficient flight patterns。 Eurlings said he expects authorization to be granted soon for KLM's flights using the new fuel。 An Air France-KLM Boeing 747 using a 50 per cent biofuel mix in one engine successfully completed a demonstration flight in the Netherlands in November 2009. |
