Switzerland tops the global list of countries ranked by environmental performance according to the 2008 Environmental Performance Index (EPI) produced by a team of environmental experts at Yale University and Columbia University.
The 2008 Environmental Peformance Index (EPI) (minisite) released at the World Economic Forum in Davos ranks 149 countries (rankings), on 25 indicators tracked across six established policy categories: Environmental Health, Air Pollution, Water Resources, Biodiversity and Habitat, Productive Natural Resources, and Climate Change. The EPI identifies broadly-accepted targets for environmental performance and measures how close each country comes to these goals. As a quantitative gauge of pollution control and natural resource management results, the Index provides a powerful tool for improving policymaking and shifting environmental decisionmaking onto firmer analytic foundations.
The 2008 EPI ranks Sweden, Norway, Finland, and Costa Rica two to five, respectively. Mali, Mauritania, Sierra Leone, Angola, and Niger occupy the bottom five positions.
Ireland gets a 34th ranking - down from a 10th placing in 2006. News in the past year of drinking water pollution and threats of legal action by the European Commission to enforce water standards, clearly have had an impact,
The Index also provides "peer group" rankings for each country showing how its performance stacks up against others facing similar environmental challenges. These benchmarks allow easy tracking of leaders and laggards on an issue-by-issue and aggregate basis. The data also support efforts to identify "best practices" in the environmental realm.
Analysis of the drivers underlying the 2008 rankings suggests that wealth is a major determinant of environmental success. At every level of development, however, some countries achieve results that far exceed their peers, demonstrating that policy choices also affect performance. For example, Costa Rica (5th), known for its substantial environmental efforts, significantly outperforms its neighbor Nicaragua (77th). Nicaragua%s history of poor governance and political corruption, violent conflicts, and budgets skewed towards the military instead of environmental infrastructure no doubt adds to the disparity.
Top-ranked countries have all invested in water and air pollution control and other elements of environmental infrastructure and have adopted policy measures to mitigate the pollution harms caused by economic activities. Low-ranked countries typically have not made investments in environmental public health and have weak policy regimes.
"As the corporate sector has long understood, the ability to benchmark performance provides an important spur to lagging performers and valuable guidance on where to look for best practices,"observed Daniel C. Esty, Director of the Yale Center for Environmental Law and Policy and Hillhouse Professor of Environmental Law and Policy. "Every country has something to learn from the 2008 EPI. Even the top-ranked countries underperform on some issues."
The United States placed 39th in the rankings, significantly behind other industrialized nations like the United Kingdom (14th) and Japan (21st). The United States ranked 11th in the Americas, and 22 members of the European Union outrank the United States. The U.S. score reflects top-tier performance in several indicators, including provision of safe drinking water, sanitation, and forest management. But poor scores on greenhouse gas emissions and the impacts of air pollution on ecosystems dragged down the overall U.S. rank.
"The United States% performance indicates that the next administration must not ignore the ecosystem impacts of environmental as well as agricultural, energy and water management policies,"said Gus Speth, Dean of the Yale School of Forestry and Environmental Studies. "The EPI%s climate change metrics ranking the United States alongside India and China near the bottom of the world%s table are a national disgrace."
Russia by comparison gets a 28th ranking but that is based on average for a large landmass where Western Russia is highly polluted and the unpopulated East scores highly.
The Environmental Performance Index aims to promote data-driven and analytically rigorous environmental decision making by using the best global datasets available. Yet serious data gaps limit the ability to measure performance on a number of important issues, and the overall data quality and availability for some countries are poor. Incomplete data excluded 89 countries from the 2008 EPI. The absence of broadly collected and methodologically consistent indicators for even the most basic issues such as water quality, and the complete lack of time-series data for most countries, hampers efforts to shift pollution control and natural resource management onto more empirical foundations.
"At a time when so much scientific evidence is telling us that the Earth's ecosystems are in crisis, it is inexcusable that our collective investment in environmental monitoring is so low. For some critical issues such as water it is actually decreasing. When a hospital patient's health worsens, doctors increase their monitoring, and we need to do the same for the planet," declared Marc Levy, Deputy Director of Columbia's Center for International Earth Science Information Network and one of the EPI project leaders.
