We help policymakers and industry make informed decisions about sustainable aviation.

Independent analysis and whole-system insight into aviation transition.

The 2030 sustainable aviation goals establish a strict five-year roadmap to activate four breakthrough, system-wide transformations and avoid derailing the aviation sector’s goal of reaching net-zero climate impact by 2050.

Aviation

Operation blue skies

Rerouting flights to avoid contrail formation could reduce aviation’s total climate impact by up to 40% — at an average cost of just 1% on a ticket price.

Systems efficiency

Flying slower, replacing fleets faster, and matching aircraft to routes could cut aviation fuel burn by up to 50% by 2050 without any new technology.

Truly sustainable and scalable fuel

Sustainable aviation fuel can deliver 50–70% emissions reductions by 2050, but only if governments act now to coordinate biomass use across sectors.

Moonshots

Investing immediately in frontier technologies like hydrogen propulsion gives governments a once-in-a-generation opportunity to lead a new industry.
