International Banking Environmental Protection Act of 1989

International Banking Environmental Protection Act of 1989 - Amends the International Financial Institutions Act to preclude the U.S. Executive Director of a multilateral development bank from voting in favor of any proposed action which would have a significant environmental impact unless a comprehensive environmental impact assessment has been furnished. Requires that: (1) an environmental impact assessment accompany loan proposals through the agency review process; (2) such banks develop and make available to member governments and borrowers a systematic environmental assessment procedure for development projects; and (3) appropriate U.S. Government personnel be made available to train and assist bank staff in making environmental impact assessments.

Directs the Secretary of the Treasury to report to certain congressional committees on the efficacy of U.S. efforts to encourage consistent and timely environmental impact assessments of proposed multilateral development bank actions.
