Contact Information
This section aims to support the local communities and local CSO to get to know which stakeholders are involved in a project with their roles and responsibilities. If available, there may be a complaint office for the respective bank which operates independently to receive and determine violations in policy and practice. Independent Accountability Mechanisms receive and respond to complaints. Most Independent Accountability Mechanisms offer two functions for addressing complaints: dispute resolution and compliance review.


Unlike many other development finance institutions, DFC does not currently have an access to information policy.


Under the United States Freedom of Information Act (FOIA), DFC is obliged to respond to reasonably formulated requests for Agency records. However, DFC may apply exemptions from release to certain types of information and may charge fees in responding to requests. DFC has a designated FOIA officer who is trained in how to respond to requests and implement the law. You can learn more about filing a FOIA request at:



The Office of Accountability is an independent office that addresses complaints about environmental or social issues related to DFC-supported projects. The office provides communities an opportunity to have concerns independently reviewed and addressed. If you submit a complaint to the Office of Accountability, it may assist you by either seeking to address your problems by facilitating a problem solving dialogue between you and those implementing the project and/or investigating whether the DFC complied with its policies to prevent environmental, social, human rights, and labor harms.
