Benefits of Global Action on Climate Change

Earth as seen from space

IEc recently supported EPA’s Climate Change Division in producing two comprehensive reports on the physical and economic benefits to the U.S. of reducing global greenhouse gas (GHG) emissions. The reports are a product of EPA’s Climate Impacts and Risk Analysis (CIRA) project, which quantifies damages to multiple sectors of the U.S. economy (e.g., infrastructure, health, and water) resulting from climate change under multiple scenarios.

The first report, Climate Change in the United States: Benefits of Global Action, includes analyses designed and executed by IEc staff, including those focused on infrastructure, water quality, water supply, and wildfire damages. In addition, our consultants drafted methodological summaries for all the analyses; compiled essential data; and developed numerous charts and other graphics to highlight key findings. IEc also oversaw the development of the CIRA website; created infographics and designed the layout of the report; assisted in responding to peer review comments on the draft report; and supported the report’s release through the development of presentations, talking points, and one-pagers.

The second report, Multi-Model Framework for Quantitative Sectoral Impacts Analysis, presents the results of the second phase of the CIRA project, with the goal of informing 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, including those related to 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). Our consultants again played a central role in the development of the report, including drafting and editing text and developing infographics, maps, and charts to highlight key findings for all the analyses included in the report.
