2010 Index Rates How Close a Country is to Environmental Benchmarks

The 2010 Environmental Performance Index (EPI), which ranks 163 countries on environmental performance, has been released at the World Economic Forum Annual Meeting 2010 in Davos, Switzerland. The Index, produced every two years since 2006 by researchers at CIESIN and Yale University’s Center for Environmental Law and Policy, is based on twenty-five indicators grouped within ten core policy categories—including environmental health, air quality, water resource management, biodiversity and habitat, forestry, fisheries, agriculture, and climate change—in the context of two objectives: environmental health and ecosystem vitality. The EPI’s proximity-to-target approach, in which each country’s performance is measured against clearly defined targets, enables comparisons among countries with very different characteristics.

Although some rankings have changed dramatically—the U.S. dropped from 39^th to 61^st place since the 2008 index, for example—so too have the methodologies and data. “A better focus is the comprehensive country profiles, which present a measurement across the different environmental indicators,” says CIESIN senior research associate Alex de Sherbinin, a co-author on the report. These profiles, designed by CIESIN research associate Valentina Mara in conjunction with the Yale team, show a country’s scores for the indicators, policy categories, and objectives. Drilling down here, de Sherbinin points out, can help decision makers identify the needed focus of attention for a particular country. Geographic information specialist Malanding Jaiteh, CIESIN deputy director and EPI project leader Marc Levy, and senior research staff assistant Paola Kim were also part of the CIESIN team.

Analysis shows that income is a major factor in high environmental performance, but that policy choices may trump economic capacities. For example, the differences between neighboring countries Chile (ranked 16^th) and Argentina (70^th), or between Malaysia (55^th) and Thailand (68^th), have a lot to do with different approaches to environmental policy and governance. The biggest changes this year were seen in the scores for air pollution and effects on ecosystems, and a new indicator, water scarcity, was added. The indicators were drawn from international organizations such as the World Bank, the UN Development Programme (UNDP), and the Food and Agriculture Organization of the United Nations (FAO). Some of the data sets are drawn from government reporting that is not subject to external validation, and incomplete data have resulted in incomplete representation of countries. The report calls for greater investment by the world community in environmental monitoring, and for data sharing and transparency on the part of national governments.
