Compounded Vulnerability: Spatial Patterns of Energy Burden, Heat Exposure, and Pollution in New York City

Abstract

Energy insecurity and climate risk increasingly intersect in urban areas, yet they are often treated as separate challenges. This paper examines how household energy affordability stress, extreme heat exposure, and ambient air pollution overlap across urban space, using New York City as a case study. We introduce the concept of compounded vulnerability to describe neighborhoods where high energy burden and high heat exposure coincide, potentially intensifying environmental and health risks. Drawing on tract-level energy burden estimates, satellite-derived surface temperature measures, and summer PM2.5 concentrations, we combine a place-based interpretation of urban infrastructure and historical disinvestment with a tract-level empirical analysis of co-located risks. We document spatial co-location of economic and environmental stressors: neighborhoods facing higher energy burden are, on average, hotter, and areas experiencing joint exposure to heat and energy stress are also situated in environments characterized by elevated summer pollution. These patterns point to a plausible urban mechanism through which climatic extremes interact with energy systems and the built environment, shaping unequal exposure during periods of peak stress.
