Assessing the Costs of Adaptation

A new report published by the International Institute for Environment and Development argues that much of the oft-discussed estimates of global adaptation costs for climate change are serious underestimates. Assessing the Costs of Adaptation to Climate Change: A Critique of the UNFCCC Estimates cites a number of factors that have been overlooked in existing estimates including a) excluded sectors, b) incomplete coverage of those sectors that have been included and c) an 'adaptation deficit' due to historical underinvestment by some regions and nations. The report stops short of updating estimates of adaptation costs based upon these criticisms, but argues that such updates are needed.
