BELEM: Lobbyists tied to the fossil fuel industry have turned up in strength at the UN climate talks in the Brazilian Amazon, an NGO coalition said Friday, warning that their presence undermines the process.

A total of 1,602 delegates with links to the oil, gas and coal sectors have headed to Belem, equivalent to around one in 25 participants, according to Kick Big Polluters Out (KBPO), which analyzed the list of attendees.

By comparison, hosts Brazil have sent 3,805 delegates.

The list compiled by KBPO includes representatives of energy giants ExxonMobil, Chevron, Shell and TotalEnergies, as well as state-owned oil firms from Africa, Brazil, China and the Gulf.

But it also includes personnel from a broad range of companies such as German automaker Volkswagen or Danish shipping giant Maersk, or representatives of trade associations and other groups.
