Pressure is building to reach net zero emissions by 2050. To do this, collaboration across the industry is key and was demonstrated at the Airbus Summit in September. Aerospace experts, operators, journalists, influencers and policy makers worldwide joined this sustainability and decarbonisation discussion to explore innovations and cross-sector partnerships that will change the way we travel forever.

From energy providers and technology experts to airports and airlines, the overwhelming message is that the industry must act now, together, in a race towards sustainability which will require speed, efficiency and a global approach.


Making flights more efficient

Airlines have already been taking measures to support the sustainability cause. Globally, they are replacing ageing aircraft with more efficient ones and many are involved in carbon offset programmes or sustainability projects.

ALBATROSS - The most efficient flight

An Air France A320 flew to the summit to showcase “the most efficient flight”. This demo is part of Albatross, a European aviation partnership to explore how existing technical and operational innovations can be combined to further reduce the environmental footprint of aviation.

ATM (Air Traffic Management) can have a powerful impact on flight emissions. As such, it is considered as an area for review and development in order to ensure better and more efficient airspace management.

New energies

Enthusiasm for Sustainable Aviation Fuel (SAF) as today’s alternative to fossil fuel is rising, with the challenge now being to make it more widely available and adopted. However, it certainly needs to be scaled up to meet demand which will go well beyond 2035.

All Airbus aircraft are currently certified to operate on up to a 50% blend of SAF mixed with kerosene and Airbus has the ambition to achieve certification of 100% unblended SAF by the end of this decade.

Other high-potential alternative energies for future aircraft include electricity and hydrogen which could enable zero CO2 emissions.

Ways to reduce CO2:

  • Improved ground operations
  • Carbon offset programmes
  • SAF
  • New efficient engines and aircraft
  • Optimised ATM
  • Hydrogen and electric energies


Investing in the future

Airlines such as Delta, easyJet and SAS have noted that their customers feel increasingly concerned by the environment and are eager to see lower flight emissions. At the same time, there are naturally concerns about the investment required to support future solutions and their infrastructures - be it SAF, hydrogen, or electric-powered flights.

The Airbus ZEROe passenger aircraft* could enter service by 2035. Developing the concept has enabled a huge increase in technological knowledge, but has also shown the challenges including energy sourcing, infrastructures, regulations and policies.

Connecting ecosystems

Cross-functional teams within Airbus - from Commercial Aircraft, Helicopters, and Defence and Space - are already working on emission and noise reduction, sustainable fuels, energy efficiency, aerodynamics and new materials.
And throughout the wider aeronautical ecosystem, including regulators, governments, suppliers and airlines, new partnerships and collaborations are developing.

A global coordinated effort is crucial - it is time to act.
