- Fly more efficient aircraft.
- Use new technologies to set more efficient flightpaths and reduce delays.
- Use sustainable lower-carbon alternative fuels.
- Invest in emissions offsets within or outside of the aviation sector.
Air traffic represents less than 2-3% of the global CO2 emissions whereas road traffic accounts for around 10% of these direct emissions. Still, planes remain among the most polluting means of transport, together with cars.

Flying economy class also reduces carbon emissions relative to business or first class, in part because it maximizes the capacity of the airplane. And flying shorter distances produces fewer emissions than longer distances.

In fact, if the entire aviation sector were a country, it would be one of the top 10 carbon-polluting nations on the planet. Air travel is also currently the most carbon intensive activity an individual can make.

Low prices and an ever-expanding route network make it possible: 9 billion passengers are expected in the air by 2050. Thus, the passenger volume in aviation of the future will more than double compared to the current level.
