KLM Royal Dutch Airlines has signed a three-year contract for the supply of sustainable biofuel in Los Angeles. This means that KLM will purchase sustainable biofuel for all its flights at this airport for a period of three years. The biofuel will be produced by the local biofuel refinery AltAir Fuels and supplied by SkyNRG. Los Angeles is the world’s second airport that has incorporated biofuel into its regular refuelling process. The airport in Oslo, Norway, was first to do so in March this year. KLM was also involved in that initiative.
