As of December 31, 2020, the North American Development Bank has certified and funded 275 environmental infrastructure projects, of which 239 have been built and are operational. A total of 124 of these operational projects have undergone a closeout process to verify their actual performance versus the intended performance at certification. This report documents the aggregate results of these 124 projects. An additional 82 projects are operational but have not yet been closed out, thus the actual impact of the Bank’s projects is greater than the results verified and presented in this report.
