2018 Environmental Performance Index (EPI)

The 2018 Environmental Performance Index (EPI) ranks 180 countries on 24 performance indicators in the following 10 issue categories: air quality, water and sanitation, heavy metals, biodiversity and habitat, forests, fisheries, climate and energy, air pollution, water resources, and agriculture. These categories track performance and progress on two broad policy objectives, environmental health and ecosystem vitality. The EPI's proximity-to-target methodology facilitates cross-country comparisons among economic and regional peer groups. The data set includes the 2018 EPI, component scores, and time-series source data. The 2018 EPI was formally released in Davos, Switzerland, at the annual meeting of the World Economic Forum in January 2018. It is the result of collaboration of the Yale Center for Environmental Law and Policy (YCELP), Yale University, Columbia University Center for International Earth Science Information Network (CIESIN), and the World Economic Forum (WEF). The Interactive Website for the 2018 EPI is at https://epi.envirocenter.yale.edu/.

2018年环境绩效指数（EPI）对180个国家在以下十个问题类别中的24项绩效指标进行了排名：空气质量、水资源与卫生、重金属、生物多样性与栖息地、森林、渔业、气候与能源、空气污染、水资源和农业。这些类别追踪环境健康和生态系统活力两大广泛政策目标的表现与进步。EPI的接近目标方法促进了经济和地区同行群体间的跨国比较。该数据集包括2018年EPI、组成部分得分以及时间序列源数据。2018年EPI于2018年1月在瑞士达沃斯举行的世界经济论坛年会期间正式发布。这是由耶鲁大学环境法律与政策中心（YCELP）、耶鲁大学、哥伦比亚大学国际地球科学信息网络中心（CIESIN）和世界经济论坛（WEF）合作完成的结果。2018年EPI的交互式网站位于https://epi.envirocenter.yale.edu/。
