Copyright © 2001 The Trustees of Columbia University in the City of New York. Key Findings Measuring Environmental Sustainability is Possible  ESI Ranks 122 countries  Based on 67 empirical measurements Economic conditions are important, but not a fundamental policy constraint  Among countries at similar income levels, there is no correlation between GDP/capita and ESI. Data limitations present severe constraint on shift toward more analytically rigorous environmental decision-making

Copyright © 2001 The Trustees of Columbia University in the City of New York. ESI’s Purpose: Benchmark environmental performance Identify comparatively environmental results that are above or below expectations Identify “best practices” Investigate interactions between environmental and economic performance

Copyright © 2001 The Trustees of Columbia University in the City of New York. Methodology: Guiding Principles Create ESI in a systematic, transparent, and reproducible manner. Be faithful to scientific literature as well as relevant to the major policy debates. Be applicable to a wide range of situations and conditions. Make use of what can actually be measured today but leave room for movement tomorrow.

Analysis Spot broad patterns Identify successful (and failing) policies Explore correlations between environment and other factors (corruption, income, population) Specify causal relationships and drivers of good environmental performance

Can poor countries afford good environmental performance? Does strong environmental performance harm national competitiveness?

Conclusions Strengths of ESI  Measures Environmental Sustainability  Permits cross-country comparisons  Method is transparent, reproducible  Enhances capacity to benchmark performance, guide policy, deepen understanding Weaknesses  Assumes particular set of weights  Suffers from gaps in available data  Lacks time series data which limits ability to identify policy drivers
