KLM has a Corporate BioFuel Programme since 2009 to source sustainable biofuel for its airline customers. The programme addresses the key challenges of biofuel availability, sustainability, and affordability. Through the programme, KLM analyzes customer flight routes and volumes to determine a premium paid by the customer to source biofuel at the best available price. This creates a platform for customers, KLM, and partners to accelerate the development of sustainable air travel.
