International Energy Agency: Assessment of U.S. Participation in the Fifth Allocation System Test

In response to a congressional request, GAO reviewed U.S. participation in the most recent test of the International Energy Agency's (IEA) emergency oil sharing system (AST-5), focusing on: (1) how members designed the test and how well it met its objectives; (2) U.S. participation and performance; and (3) the extent to which AST-5 and U.S. participation in it meaningfully exercised U.S. energy emergency preparedness plans and provided useful training.
