In 2018 the airport applied to extend the airport to allow a growth in passenger numbers to 12 million. The plan involved enlarging the passenger terminus and plane taxiways. It also planned to add parking for 3,000 more cars, much of it on greenbelt land. There was much resistance to the plan with 84% of North Somerset residents who commented rejecting the expansion plan. Bristol Airport Action Network (BAAN), a network of organisations including Extinction Rebellion, North Somerset Parishes, Stop Airport Expansion, Friends of the Earth & Greenpeace organised a huge resistance. This culminated in North Somerset council voting 18 to 7 to reject the plan on 10 February 2020. It said the detrimental effect on the area and the wider impact on the environment outweighed the narrower benefits to airport expansion. The airport lodged an appeal, and a four-week public inquiry is due to start in July 2021.
