National environmental performance: an empirical analysis of policy results and determinants

Abstract

Efforts to identify the determinants of environmental policy success have largely been anecdotal and case study based. This article seeks to shift environmental policy analysis on to more analytically rigorous and empirical foundations. Using statistical analysis, we identify a set of factors that drive environmental performance as measured by levels of urban particulates, sulfur dioxide, and energy use per unit of GDP. Although the data are imperfect and causal linkages cannot be definitively established, the statistical analysis presented suggests that environmental results vary not only with income levels as suggested by the environmental Kuznet's curve literature but also with both the sophistication of a nation's regulatory regime and perhaps more notably, its broader economic and social circumstances.
