The accord confirms commitment in support of the Paris Agreement’s goal to restrict the rise in global average temperatures to 1.5C.

The agreement, led by the Air Transport Action Group, updates an earlier industry-wide goal set in 2009.

The pledge stated: “Global civil aviation operations will achieve net-zero carbon emissions by 2050, supported by accelerated efficiency measures, energy transition and innovation across the aviation sector and in partnership with governments around the world.”

Haldane Dodd, ATAG acting executive director, said: “Aviation has increased its ambition in line with the need for all sectors of the economy to pursue rigorous climate action. 

“Despite having endured the greatest crisis in aviation history, this new agreement shows that our sector has placed climate action as one of its highest priorities. 

“It will be a significant challenge to meet net-zero carbon emissions by 2050, but the evidence shows that with the right support from governments and efforts across the value chain, especially the energy industry, it is achievable.”

The pledge includes development of Sustainable Aviation Fuels and green hydrogen and electric power. It also envisages short-term use of carbon offsetting giving way to long-term removal of residual carbon emissions and more efficient use of airspace.

The document said: “We are committed to ensuring that aviation in 2050 will be able to meet the needs of over 10 billion passengers, connecting the world safely, securely and importantly, sustainably.”
