The World Economic Forum’s Clean Skies for Tomorrow (CST) initiative is a coalition of leaders throughout the aviation value chain facilitating 

the transition to net-zero flying by mid-century. 

A public-private-partnership, CST is focused on advancing the deployment of sustainable aviation fuels and other clean propulsion technologies. CST also serves as a key aviation industry pillar within the Mission Possible Partnership, a broader alliance of leaders focused on decarbonizing the world’s highest emitting industries.

In the context of the European Green Deal, European members of the CST community developed in 2020 a Joint Policy Proposal to accelerate the transition to net-zero CO2 emissions in aviation in Europe, with a particular focus on increasing the uptake of SAF over the next decade to start reducing emissions from the sector and to develop the value chain and bring SAF costs down.
