More than 1,600 fossil fuel lobbyists have been granted access to the Cop30 climate negotiations in Belém, significantly outnumbering every single country’s delegation apart from the host Brazil, new analysis has found.

One in every 25 participants at this year’s UN climate summit is a fossil fuel lobbyist, according to the analysis by the Kick Big Polluters Out (KBPO) coalition, raising serious questions about the corporate capture and credibility of the annual Cop negotiations.

This year’s tally represents a 12% rise from last year’s climate talks in Baku, Azerbaijan, and is the largest concentration of fossil fuel lobbyists at Cop since KBPO first began exposing industry participation in 2021.
