Dr Reiner, a regular contributor to CISL’s executive programmes and business platforms, explains in this interview what we can learn from the controversies surrounding carbon dioxide capture and storage. His explorations of the views of different environmentalists, and the way politicians and the energy industry communicate with the public, reveal challenges both for the ‘green’ movement, and for the whole of society as we try to establish trust and consensus in the face of climate change. Interview by Wayne Visser and Francesca Raphaely.
