The "International Aviation Climate Ambition Coalition" was introduced at Cop26 and has been signed by 21 other member states, including Canada, France, Japan and Italy.
In agreeing to the declaration, the signatories will acknowledge the impact Covid-19 continues to have on the sector and the need to develop initiatives that enable the aviation industry to "continue to build back better" and grow in a "sustainable manner".
It will also emphasise that international action on tackling aviation emissions is "essential", given the global nature of the sector.
