2What is Sustainable Development? The Brundlant Commission Report (1987) gives the standard definitionSD="Meeting the needs of the present without compromising the ability of future generations to meet their own needs”Aspects of SD:Economic,Social/Political,Environmental
3Environmental Sustainability Index 2002 An Initiative of the Global Leaders for Tomorrow Environment Task Force,World Economic Forum
4From WEF (2002): “Strengths of ESI + Measures Environmental Sustainability+ Permits cross-country comparisons+ Method is transparent, reproducible+ Enhances capacity to benchmark performance, guide policy, deepen understandingWeaknesses- Assumes particular set of weights (!)- Suffers from gaps in available data- Lacks time series data which limits ability to identify policy drivers”

7Points of departureBroader scope of SD that accounts for economic, social-political, and environmental aspectsMeta-level approach (index of indices)Emphasis on developing a weighting mechanism which neither specifies weights a priori nor allows for any weights that show the country in positive light (weight-restricted DEA).
103 types of weight restrictions: Relative weight between 2 SD indicators (h,i) for a given country jRelative weight between SD categories (k,l) for a given country jRelative weight of the given indicator i between 2 countries (j,k)
18ConclusionsDEA appears a promising tool for weighting multiple dimensions of SD to identify benchmarks.Normative judgement on min/max bounds for weights seems less controversial than choice of any specific set of weights.Weight flexibility can be restricted across SD outputs, but also across output categories and countries.
19Challenges for future research Constructing a ‘superior’ SD index directly from measures and indicators, rather than using aggregated indices.Dynamic index: Measuring a rate of change in the stock variables, instead of mixing up stocks and flows. A Malmquist index approach.
