2002 Environmental Sustainability Index (ESI)

The 2002 Environmental Sustainability Index (ESI) measures overall progress toward environmental sustainability for 142 countries based on environmental systems, stresses, human vulnerability, social and institutional capacity and global stewardship. The addition of a climate change indicator, reduction in number of capacity indicators, and an improved imputation methodology contributed to an improvement from the 2001 ESI. The index was unveiled at the World Economic Forum's annual meeting, January 2002, New York. The 2002 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).

2002年环境可持续性指数（ESI）以环境系统、压力、人类脆弱性、社会及制度能力以及全球治理为依据，对142个国家的环境可持续性整体进展进行了衡量。该指数的构建在引入气候变化指标、减少能力指标数量以及改进插补方法的基础上，相较于2001年ESI有所提升。该指数于2002年1月在纽约世界经济论坛的年度会议上正式公布。2002年ESI的编制是世界经济论坛（WEF）、耶鲁环境法律与政策中心（YCELP）以及哥伦比亚大学国际地球科学信息网络中心（CIESIN）三方合作的成果。
