This article examines the drivers of American support for environmental projects in the multilateral development banks (MDBs). We first describe how U.S. Executive Directors are guided by Congressional directives regarding environmental aspects of MDB projects. The article then turns to statistical analysis of the strategic and normative drivers of U.S. positions on MDB projects. Our analysis finds mixed support for environmental factors driving U.S. votes. The United States is more inclined to vote against “dirty” projects (i.e., mining, coal, and oil) rather than specifically support “green” projects (i.e., projects related toward climate change or biodiversity). The overall environmental performance of a country had a minor influence on whether the United States would support proposals from that country, but the United States was much more likely to disapprove of a project if a project failed to undergo an environmental analysis or failed the analysis in anyway.

投票给绿色？美国对多边开发银行环境项目的支持

本文考察了美国支持多边开发银行 (MDB) 环境项目的驱动因素。我们首先描述美国执行董事如何遵循国会关于 MDB 项目环境方面的指令。然后，文章转向对美国对多边开发银行项目的立场的战略和规范驱动因素的统计分析。我们的分析发现，对推动美国投票的环境因素的支持不一。美国更倾向于投票反对“肮脏”项目（即采矿、煤炭和石油），而不是专门支持“绿色”项目（即与气候变化或生物多样性相关的项目）。一个国家的整体环境表现对美国是否支持该国的提案影响不大，
