Cop28 organisers granted attendance to at least 475 lobbyists working on carbon capture and storage (CCS), unproven technologies that climate scientists say will not curtail global heating, the Guardian can reveal.

The figure was calculated by the Centre for Environmental Law (Ciel) and shared exclusively with the Guardian, and is the first attempt to monitor the growing influence of the CCS subset of the fossil fuel industry within the UN climate talks.
