IEc has been a leader in the climate change impacts and adaptation field since the publication of our ground-breaking work in the late 1990s, The Impact of Climate Change on the US Economy (Cambridge University Press, 1999). Since that time, IEc has collaborated with some of the world’s best known climate scientists, biophysical modelers, and economists to both advance the science of impact assessment and develop practical advice for policy-makers, regulators, and development institutions, ranging from the Agriculture and Environment Ministers of developing countries to the U.S. Environmental Protection Agency (EPA). Our work also contributes substantively to analysis of the benefits of greenhouse gas regulation. Key areas of focus include:

  • Water Resources: See our analysis of the risk of climate change-induced drought in the U.S.
  • Infrastructure: Support of an adaptation project for the nonprofit Resources for the Future, which focused on infrastructure resources (including roads and urban drainage as well as climate change).
  • Coastal: IEc's models of sea-level rise and storm surge impact are used by EPA and local governments to estimate impacts and assess the efficiency for adaptive measures in the coastal zone. Recent published works include "The Economics of Adaptation Along Developed Coastlines" and "Assessing Sea-Level Rise Impacts."
  • Developing country contexts: IEc supported the World Bank in estimating the impact of cyclone-induced storm surge in Mozambique, part of their Economics of Adaptation to Climate Change program.
  • Climate Change Impacts and Risk Analysis: IEc supported EPA in developing a report documenting methods and results from the second phase of the Climate Change Impacts and Risk Analysis (CIRA) project. The goal of this work is to estimate climate change impacts and economic damages to multiple U.S. sectors under different scenarios. The effort is intended to inform the fourth National Climate Assessment (NCA4) of the U.S. Global Change Research Program (USGCRP). IEc staff designed and executed ten of the analyses featured in the report: infrastructure (roads, bridges, rail, Alaska infrastructure, urban drainage, and coastal property); health (water quality and harmful algal blooms); and water resources (water quality, and municipal and industrial water supply).
