Global Aviation Sustainability Outlook 2025

Expectations around greenwashing for 2025 BOX 3 Looking ahead into 2025, stakeholders interviewed expect concerns around greenwashing to evolve differently across different regions. Europe is likely to see closer scrutiny of environmental claims by aviation stakeholders. Meanwhile, in the US, an expected decrease in communication and advertisement campaigns on ESG-related activities (including SAF) may lead to less emphasis on this issue. Nevertheless, striving for more consistent and aligned approaches to sustainability across regions will most likely remain a priority for many stakeholders. Aligning sustainability criteria and taxonomies is predicted to feature in many international discussions, including at the G20 as well as in ICAO, where work to develop the Finvest Hub proposition continues, following progress announced at the Global Implementation Support Symposium in February 2025.71 Airlines may choose to voluntarily improve transparency and simplify information provided to passengers – especially in Europe, where a new labelling scheme is being introduced in summer 2025.72 This could potentially improve consumers’ willingness to pay for decarbonization, given that voluntary “pay-for- SAF” options embedded into airlines’ booking platforms were reported to have gained some limited traction with passengers in 2024.
