This talk will explore governance of sunlight reflection methods through an international Albedo Accord which can begin to restore the 2% of planetary brightness that has been lost this century, in recognition that darkening is now the primary driver of heat. The Albedo Accord can be modelled on the success of the Montreal Protocol on the ozone layer, through partnership between business, science and government, enabling an evidence-based balance between action on albedo and on carbon to reverse global warming.

Robert Tulip is a member of the Steering Circle for the Healthy Planet Action Coalition and is writing a book on the proposal for an Albedo Accord. He worked for three decades for the Australian Government in international development and has a Masters degree in existential ethics.
