Increased use of renewable energy
Schiphol Group is transitioning to renewable energy sources. All the airports in the Royal Schiphol Group are 100% powered by wind energy, we use thermal storage to heat and cool more buildings and we are installing more solar panels. Many of our vehicles are already electric and we are continuing to add to their number.

Fixed Electrical Ground Power
Stationary aircraft normally use their kerosene-driven auxiliary motors or a diesel generator to supply electricity and climate control. To reduce this, we have equipped 73 aircraft stands with installations for Fixed Electrical Ground Power (400 Hz) and pre-conditioned air. As a result, aircraft at the aircraft stands no longer need to hook up their auxiliary motors to a kerosene- or diesel-powered generator or a pre-conditioned air unit.
Electricity for the aircraft
Aircraft parked on the apron, rather than at a gate, source their energy from a mobile Ground Power Unit (GPU). Schiphol recently launched a pilot using four electric GPUs that replace diesel generators and help reduce the airport’s emissions. If this test is successful, every aircraft stand that does not currently have Fixed Electrical Ground Power in place will be equipped with an e-GPU.
GTL for traffic on apron
KLM is currently using gas-to-liquid (GTL) diesel for its apron traffic (baggage trains, pushback tractors, loading platforms) as a temporary measure until all these vehicles have been converted to electric power. GTL is a cleaner alternative to diesel that contains smaller amounts of pollutants. Initial measurements suggest that GTL leads to a reduction in nitrogen oxide emissions of between 16% and 18%.
Sustainable buildings
Many of the buildings – offices, terminal, car parks – at our airports are built and managed to LEED gold certificate standards: the second-highest possible sustainability certificate. To achieve this certificate, buildings are assessed in areas such as water conservation, energy efficiency, material choice, indoor environments and innovation.
Lelystad Airport
Almost all ground handling activities for aircraft at Lelystad Airport have been converted to electric power.
