The tools apply an Exposure–Impact–Adaptive-capacity framework to assess risks. The framework incorporates elements of the risk analysis framework adopted by the Intergovernmental Panel on Climate Change (IPCC) and the framework for vulnerability assessment used by the United States Agency for International Development’s (USAID’s), with some modifications.
