At a high-level conference on climate change at Chatham House, London, two activists interrupted first Peter Kent, Canada’s Environment Minister, then Shell’s UK Chairman Graham van’t Hoff, as they got up to make speeches. The conference attendees included EU Climate Commissioner Connie Hedegaard, UNFCCC Executive Secretary Christiana Figueres and Professor Thomas Stocker from the Intergovernmental Panel on Climate Change. There was laughter at the tongue-in-cheek speeches which referred to Kent as an “agent from a rogue petro-state” and Shell as “world-class greenwashers”, and the audience listened attentively for several minutes, before the activists were removed by security.
