At COP29 in Baku, Azerbaijan, around 1,800 lobbyists from fossil fuel interests have gained accreditation, raising concerns among environmental activists. The coalition ‘Kick Big Polluters Out’ reports that the number of fossil fuel lobbyists exceeds the delegations from most nations, except Azerbaijan, Brazil, and Turkey. They argue this undermines the voices of countries most affected by climate change. New UN rules were implemented to identify lobbyists more easily, yet major oil companies continue to be represented, prompting calls for a focus on sustainable development and environmental justice.
