NADB and BECC were created through the Agreement between the Government of the United States of America and the Government of the United Mexican States Concerning the Establishment of a Border Environment Cooperation Commission and a North American Development Bank, which entered into effect on January 1, 1994 and was amended on August 4, 2004.
NADB was established in San Antonio, Texas, and began operations on November 10, 1994, with the initial capital subscriptions of the U.S. and Mexican governments. BECC was established in Ciudad Juarez, Chihuahua, and its operating budget is funded by contributions from the U.S. and Mexican governments.
In December 2014, the Board of Directors approved a resolution recommending that the two governments integrate BECC and NADB into a single entity to streamline their processes and increase operational efficiencies, in order to maximize the services provided to border communities and make more efficient use of available resources. Under the integration, the mission, purposes and functions of the institutions will be preserved, and the geographic jurisdiction and environmental mandate will remain unchanged. The integration is currently in process.
