The International Civil Aviation Organization (ICAO) organized five Global Aviation Dialogues (GLADs) around the world to discuss the latest draft proposal on a market based measure to curb emissions from international aviation. The dialogues came to a close on 8 April, but there are already worrying signs that important elements around ambition, emission unit quality criteria and double counting of these units may not be adequately addressed. If left untreated, these missing elements would lead to a toothless proposal that will do little for the environment.
