Development, Inequality, and Environmental Quality: an Analysis of Competing Hypotheses Using Local Areas in the United States

Much of the environmental sociology literature calls for economic development to lead to environmental destruction, but growing bodies of work on “ecological modernization” and “environmental Kuznets curves” (EKCs) argue that, beyond a certain point, socioeconomic development can lead to environmental improvement. A third hypothesis (Boyce) argues that inequality may be more relevant than levels of prosperity. Published findings have been sufficiently mixed to warrant more detailed analyses. This chapter considers both cross-sectional and two-wave panel data and the three competing expectations, considering air emissions and toxic manufacturing releases for U.S. counties. Air emissions tend to correlate positively with economic prosperity, supporting the “core” environmental sociology hypothesis, while toxic emissions show greater support for the EKC/ecological modernization hypothesis. The most consistent theoretical support is found among indicators of inequality and power that support the Boyce hypothesis. The findings suggest implications for policy as well as for future research.
