2020 Environmental Performance Index (EPI)|环境绩效指数数据集|环境保护数据集

The 2020 Environmental Performance Index (EPI) ranks 180 countries on 32 performance indicators in the following 11 issue categories: air quality, sanitation and drinking water, heavy metals, waste management, biodiversity and habitat, ecosystem services, fisheries, climate change, pollution emissions, agriculture, and water resources. 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 2020 EPI, component scores, and time-series source data. It is the result of a collaboration of the Yale Center for Environmental Law and Policy (YCELP), Yale University, and the Columbia University Center for International Earth Science Information Network (CIESIN). The Interactive Website for the 2020 EPI is at https://epi.yale.edu/.

2020年环境绩效指数（EPI）对180个国家在以下11个问题类别中的32项绩效指标进行排名：空气质量、卫生与饮用水、重金属、废物管理、生物多样性及栖息地、生态系统服务、渔业、气候变化、污染排放、农业和水资源。这些类别追踪两个广泛政策目标——环境卫生和生态系统活力——的绩效和进展。EPI的接近目标方法促进了经济和地区同行群体之间的跨国比较。数据集包括2020年EPI、组成部分得分和时间序列源数据。该数据集是耶鲁大学环境法律与政策中心（YCELP）、耶鲁大学和哥伦比亚大学国际地球科学信息网络中心（CIESIN）合作的结果。2020年EPI的交互式网站位于https://epi.yale.edu/。
