Patrick Greenfield, one of the reporters on the investigation, will detail the story of their investigation and discuss its wider implications for conservation and corporate net-zero claims.

Patrick Greenfield is a reporter for the Guardian and the Observer. He writes about biodiversity loss and the climate crisis.
