Over the past 50 years, helicopters’ CO2 emissions have been reduced by 50% thanks to a variety of engine innovations that deliver more power with fewer emissions. At Airbus, we are committed to taking more ambitious steps to reduce the environmental footprint of our helicopters to bring us closer to net-zero emissions.
Today’s helicopters play a key role in missions that help preserve the environment, such as firefighting operations or scientific projects requiring air transportation. Pioneering zero-emission flight is the latest area in which helicopters are aiming to make significant contributions.
Helicopters account for less than 1% of the aviation industry’s CO2 emissions, but efforts are underway to continue to reduce this figure. Research has shown that fuel is the main source of CO2 emissions (95%) throughout a helicopter’s lifecycle.
Thanks to joint efforts with engine manufacturers over the last five decades, the compression ratios and efficiency of helicopter turbines have increased to deliver the following results:
Airbus Helicopters is involved in a variety of research projects that aim to reduce helicopters’ CO2 emissions. A key example is the European Union’s Clean Sky programme.
