2010 Environmental Performance Index (EPI)

The 2010 Environmental Performance Index (EPI) ranks 163 countries on environmental performance based on twenty-five indicators grouped within ten core policy categories addressing environmental health, air quality, water resource management, biodiversity and habitat, forestry, fisheries, agriculture, and climate change in the context of two broad objectives: environmental health and ecosystem vitality. The EPI’s proximity-to-target methodology facilitates cross-country comparisons among economic and regional peer groups. It was formally released in Davos, Switzerland, at the annual meeting of the World Economic Forum on January 28, 2010. The 2010 EPI is the result of collaboration between the Yale Center for Environmental Law and Policy (YCELP) and the Columbia University Center for International Earth Science Information Network (CIESIN).

2010年环境绩效指数（Environmental Performance Index，EPI）以两大总体目标为框架——环境健康与生态系统活力，将25项指标归类为10项核心政策类别，涵盖环境健康、空气质量、水资源管理、生物多样性与栖息地、林业、渔业、农业及气候变化等领域，据此对163个国家的环境绩效进行排名。该指数采用的"目标贴近度"评估方法，可助力经济与区域对等群体间开展跨国对比。其于2010年1月28日在瑞士达沃斯举办的世界经济论坛年度会议上正式发布。2010年EPI由耶鲁大学环境法律与政策中心（Yale Center for Environmental Law and Policy, YCELP）与哥伦比亚大学国际地球科学信息网络中心（Center for International Earth Science Information Network, CIESIN）联合研制完成。
