Climate Vulnerability Index

Based on the peer-reviewed journal article, Characterizing vulnerabilities to climate change across the United States, a dashboard and an interactive map of the U.S. designed by Darkhorse Analytics, the CVI allows users to search by location and view their overall climate vulnerability and the conditions that shape it – from quality of housing and access to supermarkets to proximity to toxic waste sites and number of deaths from air pollution. For example, census tracts in Houston’s Settegast community rank in the 99th percentile for overall vulnerability. The CVI shows what is driving vulnerability, including low chronic disease prevention, high exposure to harmful pollutants like soot and inadequate access to fresh, nutritious food.

Pulling in 184 sets of data to rank more than 70,000 U.S. Census tracts, the U.S. Climate Vulnerability Index helps users see which communities face the greatest challenges from the impacts of a changing climate. This tool shows what factors are driving the challenges, so policymakers and communities themselves can take action to build climate resilience where it is needed most.

You can interact with the map by:

  • Searching for a location
  • Zooming and panning across different areas
  • Clicking on a location for more details
  • Adjusting the map scale filter to focus on higher vulnerability locations

Searching for Energy, the CVI map shows the sources, availability, and affodability of energy in every U.S. census tract. Zooming in on the Chicago area, for example, shows that some census tracts, such as South Side, are ranked as having the “highest vulnerability” rating, in the 95-99 percentile compared with other locations across the country. Other locations in Chicago are much less vulnerable, ranking as low as 18th percentile in terms of energy vulnerabiilty.

EDF’s new equity map shows state efforts to make the energy transition fairer for all

Across the U.S. states are passing laws that will ensure greater equity as we transition to a clean energy system. EDF has developed an interactive map – based on our new report, the State Climate Equity Survey – that documents states’ efforts to make their energy transition more equitable and healthier. Our new map identifies which states require, allow, or promote consideration of equity and environmental justice in agency decision-making and budget-setting.

Understanding energy behaviors for a more equitable future

Dr. Destenie Nock published a new study based on research in Chicago showing that low-income households turn on their cooling systems in hot weather three degrees later than higher income households, but they turn on heat in cold weather six degrees earlier than high income households, whether because of poor insulation or other reasons. “This work highlights the challenges low-income communities face. Not only are they at higher risk in the summer, but in the winter they have to spend a lot more money to protect their pipes from freezing,” noted Nock. “The financial stress of heating homes in winter can also lead to broader inequities.” Dr. Nock's data can be used to shape policies that address systemic inequities, guide investments in infrastructure, and help improve living conditions for energy-insecure and vulnerable households. Dr. Nock has provided expert testimony in Illinois rate case proceedings.

Report: managed gas transition strategies for Illinois

A new report finds that Illinois’ largest gas utilities’ current capital spending on gas systems will raise customers' rates sharply and could lead to stranded assets of $80 billion by 2050. To avoid this costly path, the report recommends a strategically managed gas transition to clean, renewable energy sources, which will also reduce the climate and air pollution Illinois currently experiences, particularly in environmental justice and low-income communities.
