KLM takes many measures to reduce its CO2 emissions.

Fleet renewal

For KLM in the financial year 2009/2010, 16 aircraft were added to the KLM fleet, as 15 older generation planes were retired.

The ten new Embraer 190s are 9% more fuel efficient than the F100, which they replace. Thanks to its continued efforts, the specific fuel consumption of the KLM group decreased by 13% since 2000. For the 2010-11 financial year, net investment of the AIR FRANCE-KLM GROUP should be €1.1 billion.

Fuel efficient flying

Weight and fuel are interlinked. KLM reduced kerosene consumption by 9.5% in five years by rigorously reducing the weight of everything in and on aircraft.

Sustainable biofuels

KLM is also looking at possible alternatives to fossil fuel. An example of this is our support for research into biomass as a basis for kerosine. Technically, it has already been shown that environmentally sustainable kerosene can be produced from biomass.



All of Boeing 737 Next Generation aircraft are equipped with winglets. These vertical wingtips improve aerodynamics and reduce fuel consumption, thus reducing CO2 emissions by about 3% for this aircraft type.

Smart aircraft deployment

KLM strives to a achieve an optimum match between aircraft type and passenger numbers – which may change over time. In the peak summer period, we will use a large Boeing 737 to fly to Venice, while in the winter we will use the smaller and more efficient Fokker 100.

Aircraft of the future

Aircraft of the future

KLM is supporting research by the Delft University of Technology to develop a new aircraft that is 50% more efficient and produces 50% less noise. KLM’s contribution to this long term project includes practical insight and data about aircraft deployment and performance. The aircraft in question, code-named CleanERA, must be ready to fly in 2025.

Better engine cleaning

Water wash

KLM has developed a means of carrying out the Engine Water Wash(PDF, 111KB) method inside the hangar during regular maintenance. The washing process uses about a 100 liters of water, which is used to rinse the engine a few times. Clean engine burn less fuel and emit less CO2.

Energy consumption on the ground

We don’t only consume energy in the air, but also on the ground. Although this only accounts for 1% of our total energy consumption, that’s enough for us to devote attention to it. We also take special measures to reduce energy consumption on the ground.
