Global air transport industry commits to net-zero carbon emissions by 2050

Global air transport industry commits to net-zero carbon emissions by 2050

The resolution aligns with the Paris Agreement goal for global warming not to exceed 1.5°C

The International Air Transport Association’s (IATA) 77th annual general meeting approved a resolution for the global air transport industry to achieve net-zero carbon emissions by 2050.

Commenting on the announcement, IATA director General Willie Walsh said: “The world’s airlines have taken a momentous decision to ensure that flying is sustainable. The post-Covid-19 reconnect will be on a clear path towards net zero. 

“That will ensure the freedom of future generations to sustainably explore, learn, trade, build markets, appreciate cultures and connect with people the world over. With the collective efforts of the entire value chain and supportive government policies, aviation will achieve net zero emissions by 2050.” 

The aviation industry must progressively reduce its emissions while accommodating the growing demand of a world that is eager to fly. To be able to serve the needs of the 10 billion people expected to fly in 2050, at least 1.8 gigatons of carbon must be abated in that year. Moreover, the net zero commitment implies that a cumulative total of 21.2 gigatons of carbon will be abated between now and 2050. 

A key immediate enabler is the International Civil Aviation Organisation’s (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). This will stabilise international emissions at 2019 levels in the short-to-medium term. Support for this was reaffirmed in the resolution.  


Walsh added: “Achieving sustainable global connectivity cannot be accomplished on the backs of airlines alone. All parts of the aviation industry must work together within a supportive government policy framework to deliver the massive changes that are needed, including an energy transition. That is no different than what we are seeing in other industries. 

“Road transport sustainability efforts, for example, are not being advanced by drivers building electric vehicles. Governments are providing policies and financial incentives for infrastructure providers, manufacturers and car owners to be able to collectively make the changes needed for a sustainable future. The same should apply to aviation.” 

The resolution calls on governments through ICAO to agree to a long-term goal equivalent to the industry’s net zero by 2050 commitment. In line with the longstanding approach to managing aviation’s climate change impact, the resolution also called for governments to support CORSIA, coordinate policy measures and avoid a patchwork of regional, national, or local measures. 

Walsh concluded: “Governments must be active partners in achieving net zero by 2050. As with all other successful energy transitions, government policies have set the course and blazed a trail towards success. The costs and investment risks are too high otherwise. The focus must be on reducing carbon.”
