Industry warns ICAO has no time to waste to endorse net zero by 2050

The global aviation industry is reasonably optimistic that the International Civil Aviation Organization (ICAO) will endorse a target to achieve net zero emissions by 2050 at the organization's 41st general assembly, which is now under way.

But even if ICAO establishes that baseline, challenges remain as differences between developing and developed countries need to be resolved.

And there is also the reality that the creation of a formal target will do little to satisfy critics, who argue that the industry is not moving fast enough to cut its emissions.
