With 80,000 attendees, COP28 is largest UN climate summit ever

[Collection]COP28 is officially the largest ever UN climate summit, with 80,000 participants registered on a list that -- for the first time -- shows who they work for. That largely exceeds the previous record at last year's UN climate summit in Egypt, COP27, which had 49,000 accredited attendees, and where oil and gas lobbyists outnumbered most national delegations, according to NGOs. This year, there are nearly 23,500 people from official government teams.
