Clean Skies for Tomorrow Coalition

Through the concerted effort of ambitious industry and state leaders, together we can put the global aviation sector on the path to net-zero emissions by 2050 by accelerating the supply and use of SAF technologies to reach 10% of global jet aviation fuel supply by 2030.

About the CST initiative

Through the CST initiative, the Forum and its partners are supporting the aviation’s industry’s ongoing transition to climate neutrality. The CST coalition and the industry as a whole are developing interventions that will incentivize leaders to act in key areas. To scale production and make SAF economically viable: technological challenges must be overcome; a supportive regulatory framework needs to be installed to stimulate demand from corporate and private customers; and innovative solutions to finance the transition have to be implemented. The CST coalition is debating how to meet these challenges and help aviation earn its right to keep growing.

The Clean Skies for Tomorrow initiative is pursuing five impact areas to help scale the production of sustainable aviation fuels:

The opportunity 

As travel picks up in the wake of the pandemic, aviation could return to producing about 2-3% of total global GHG emissions if we take no action – with overall impacts on climate change at even higher percentages as a result of climatic-forcing mechanisms. Additionally, as other sectors accelerate towards net-zero emissions, the aviation sector’s share may increase even further, and the industry, known for leading in innovation and its early climate commitments, may lag and face heavier scrutiny from society.

Members of the coalition agree that achieving net-zero in the sector will require reduction, as far as possible, of the emissions caused by the aviation sector through efforts including the optimization of routes and increased energy efficiency through the use of new aircraft and improved ground operations. Any remaining emissions must be balanced by appropriate carbon removal, so as to arrive at net-zero emissions in the sector.

Why SAF

Synthesized from sustainable, renewable feedstocks, such as municipal waste, agricultural residues and waste lipids, or developed through a power-to-liquid route, SAF has already fuelled hundreds of thousands commercial flights. It is fully compatible with existing aircraft and fuelling infrastructure, therefore reducing the amount of investment required to underpin the transition.
