2000 Pilot Environmental Sustainability Index (ESI)

The 2000 Pilot Environmental Sustainability Index (ESI) is an exploratory effort to construct an index that measures the ability of a nation's economy to achieve sustainable development, with the long term goal of finding a single indicator for environmental sustainability analagous to that of the Gross Domestic Product (GDP). The index covering 56 countries is a composite measure of the current status of a nation's environmental systems, pressures on those systems, human vulnerability to environmental change, national capacity to respond, and contributions to global environmental stewardship. The index was unveiled at the World Economic Forum's annual meeting, January 2000, Davos, Switzerland. The 2000 Pilot ESI is the result of collaboration among the World Economic Forum (WEF), Yale Center for Environmental Law and Policy (YCELP), and the Columbia University Center for International Earth Science Information Network (CIESIN).

2000年试点环境可持续性指数（ESI）是一项探索性工作，旨在构建一个衡量一个国家经济实现可持续发展能力的指数，其长期目标是找到一个与国内生产总值（GDP）相似的单一环境可持续性指标。该指数涵盖56个国家，是对一个国家环境系统当前状况、对这些系统的压力、人类对环境变化的脆弱性、国家应对能力以及对全球环境治理贡献的综合衡量。该指数于2000年1月在瑞士达沃斯的世界经济论坛年会上首次公布。2000年试点ESI是世界经济论坛（WEF）、耶鲁环境法律与政策中心（YCELP）和哥伦比亚大学国际地球科学信息网络中心（CIESIN）合作的成果。
