Three solutions helping net-zero aviation take off
March 3, 2023
- Aviation accounts for 3% of global greenhouse gas emissions in 2020, which could increase to 22% by 2050.
- Member-airlines belonging to the International Air Transport Association (IATA) have committed to reaching net-zero emissions by 2050.
- Using sustainable aviation fuels made from agricultural or forestry waste has the potential of reducing airline CO2 emissions by nearly 70%.
- Aeroplane engines are being redesigned to increase fuel efficiency and thereby decrease flight emissions. Engines with open fan architecture could reduce CO2 emissions by nearly 20% in comparison to current engines, and are slated to enter service by the mid-2030s.
- New systems in the form of hybrid-electric propulsion will also help reduce a flight’s carbon footprint by improving efficiency during all stages of the flight.
