This paper defines a policy-relevant nationwide composite index to identify communities disproportionately impacted by environmental, energy, and climate injustices in the United States. We review existing vulnerability indicators indices assess tradeoffs of different design parameters, including variable selection, geographic unit, dimensionality reduction, weighting, aggregation methods. From this methodological review, we create first nationwide, census tract-level cumulative burden that includes energy-relevant alongside climate, social, economic indicators, is flexible inclusion additional data sources. provide summary sources inputs used develop definition for "disadvantaged communities" can be prioritize energy investments. discuss use-cases implementation Justice40 Initiative, which calls 40 % certain federal clean benefits flow disadvantaged use our results examine historic allocations investments show as received about 37 fewer funds per capita than non-disadvantaged communities.

Across the Western United States, human development into wildland urban interface (WUI) is contributing to increasing wildfire damage. Given that natural disasters often cause greater harm within socio-economically vulnerable groups, research needed explore potential for disproportionate impacts associated with wildfire. Using Zillow Transaction and Assessment Database (ZTRAX), hereafter "Zillow", real estate data, we explored whether lower-priced structures were more likely be damaged during most destructive, recent wildfires in Southern California. Within fire perimeters occurring from 2000-2019, matched property price data burned unburned structures. To included final dataset, had surround at least 25 have been sold seven years before fire; five fires fit these criteria. We found evidence support our hypothesis properties damaged, however, likelihood of damage influence value significantly varied across individual perimeters. When considering individually, two 2003 fires-the Cedar Grand Prix-Old Fires-had statistically decreasing burn value. Occurring 2007 later, other three (Witch-Poomacha, Thomas, Woolsey) showed no significant relationship between Consistent studies, topographic position, slope, elevation, vegetation also a structure being Driving time nearest station previously identified hazard significant. Our results suggest further studies on extent reason are needed. In meantime, decision makers should consider allocating risk mitigation resources-such as fire-fighting structural preparedness resources-to socioeconomically neighborhoods.
