A letter report issued by the General Accounting Office with an abstract that begins "Export credit agencies (ECA) are responsible for providing billions of dollars worth of support for large-scale industrial projects annually, but until recently most ECAs did not formally review the environmental impacts of these projects. The United States, whose Export-Import Bank began using environmental guidelines in 1995, pushed for negotiations on common ECA environmental guidelines at the Organization for Economic Cooperation and Development (OECD). The OECD negotiations halted in 2001 because the United States believed that the results, called the Common Approaches, were insufficient. The remaining OECD members then pledged to voluntarily implement the Common Approaches. In response to congressional interest in ECA environmental guidelines, GAO assessed (1) the level of convergence among OECD members and the prospects for further advancement and (2) what impacts such guidelines may have on U.S. exports."

A letter report issued by the Government Accountability Office with an abstract that begins "Federal and other decision makers have had a renewed interest in how high speed rail might fit into the national transportation system and address increasing mobility constraints on highways and at airports due to congestion. GAO was asked to review (1) the factors affecting the economic viability--meaning whether total social benefits offset or justify total social costs--of high speed rail projects, including difficulties in determining the economic viability of proposed projects; (2) the challenges in developing and financing high speed rail systems; and (3) the federal role in the potential development of U.S. high speed rail systems. GAO reviewed federal legislation; interviewed federal, state, local, and private sector officials, as well as U.S. project sponsors; and reviewed high speed rail development in France, Japan, and Spain."
