KLM’s Corporate BioFuel Programme (CBP) has bagged its latest member.

Arcadis, a design and consultancy business, has signed up for the airline’s initiative, which will see their staff take flights which use a percentage of biofuel. The money generated via the programme will be used to bring down the cost differences between standard and sustainable biofuel – which is 300% more expensive than traditional jet fuel.

“Renewable biofuel contributes significantly to making air travel more sustainable. Unfortunately, sustainable biofuels are still two to three times more expensive than fossil jet fuel. KLM is trying to stimulate the market, be we cannot do it alone. We need the support of businesses and other airlines. For this reason, we are extremely pleased with Arcadis’ investment. Together with them and the other partners in the Corporate Biofuel Programme, we are taking a step forward in making civil aviation more sustainable,” said Erik Swelheim, CFO KLM.

KLM buy second generation biofuels from SkyNRG, which are made using raw materials that don’t effect the environment or food production.

Other partners of the CBP scheme include Delft University of Technology and the City of Amsterdam.
