In a pilot nation-by-nation study of environmental performance, jointly produced by Yale and Columbia Universities, Taiwan trailed most of Western Europe and Japan, but came out in front of the US which ranked 28th overall, ahead of Russia and South Korea.
The study of environmental performance shows that just six nations -- led by New Zealand, followed by five from northern Europe -- have achieved 85 percent or better success in meeting a set of critical environmental goals ranging from clean drinking water and low ozone levels to sustainable fisheries and low greenhouse gas emissions.
The bottom half of the rankings is largely filled with the countries of Africa and Central and South Asia. Pakistan and India both rank among the 20 lowest-scoring countries, with overall success rates of 41.1 percent and 47.7 percent, respectively.
The pilot study, called the 2006 Environmental Performance Index, has been reviewed by specialists both in the US and internationally.
Using a new variant of the methodology the two univer-sities have applied in their Environmental Sustainability Index, produced in four previous years, the study was intended to focus more attention on how various governments have played the environmental hands they have been dealt, said Daniel Esty, the director of the Yale Center for Environmental Law and Policy and an author of the report.
The earlier sustainability measurements "tell you something about long-term trajec-tories," Esty said. "We think this tool has a much greater appli-cation in the policy context."
For instance, Britain ranked 65th in last year's sustainability index, but fifth in the latest study, among the 133 nations measured. Among the reasons for the earlier low ranking, Esty said, was that "they cut down almost all their trees 500 years ago and before," something that modern British governments could not control.
The 16 indicators used in the latest study, the report says, provide "a powerful tool for evaluating environmental investments and improving policy results."
The report was issued during the World Economic Forum, an annual conclave of business and political leaders that met in Davos, Switzerland, the previous week. Esty said the report was also intended as a tool to help monitor progress on the environ-mental issues included among the Millennium Development goals adopted by 189 nations at the UN Millennium Summit meeting.
"It's like holding up a mirror and having someone help you see what you couldn't see before," he said. But the report acknow-ledges "serious data gaps" that resulted in leaving more than 65 countries out of the rankings. In addition, some thorny methodological issues, like how to measure land degradation or loss of wetlands, have no widely accepted solutions, the report noted, and the authors used the best measures they had available.
Like the sustainability index produced last year, the pilot study ranks countries within their geographic peer groups, so that nations in arid regions or tropical ones can be measured against one another. So Belgium's overall ranking of 39, with a 75.9 percent score, can be viewed by region and by issue. Belgium ranks last, for instance, among European countries in protection of its water resources.
Air quality rankings tend to favor less industrialized nations like Uganda, Gabon, Ecuador and Sri Lanka. Among the countries of the Americas, the US ranks in the bottom third on this scale.
