Future progress in reducing CO2 emissions from aviation?

Have you ever wondered why migratory birds fly in a V formation?

In formation, each bird benefits from the lift generated by the vortexes at the wingtips of the leading birds. This updraft helps each bird to support its own weight, which allows them to save themselves and thus be able to fly a greater distance.

Could similar results be achieved with commercial aircraft? Airbus is trying to find out.

How can high-resolution wind data be used to reduce CO2 emissions?
The UK Met Office and Norwegian test a route optimization system.

Biofuels: the future fuel of aviation?

Current turbojet engines are not designed to run on more than 10% biofuel. United Airlines has achieved a major milestone: flying on 100% biofuels on one engine.

Airbus and the German Aerospace Center (DLR) have tested the emissions associated with the use of biofuels.

According to the DLR, the carbon footprint of biofuel is significantly lower than that of kerosene throughout its life cycle, and biofuel may also be beneficial in reducing non-CO2 effects.

What are the challenges facing aviation in achieving carbon neutrality?

As passenger numbers increase and the time to reduce emissions rapidly decreases, the aviation sector must address urgent obstacles. But what exactly are they? The Guardian looks at the six obstacles in decarbonising the sector.

How can the total climate impact of aviation be reduced?

Etihad Airways estimates that it has reduced the CO2 emissions by 72% for one flight => The article is here.

Changing the altitude of 2% of flights could reduce the occurrence of contrails by 59%. => Read more.

Carbon neutral flights thanks to carbon offsetting

Le Monde and the DLR look into this practice, which is increasingly being used by airlines.
