The United Nations is making efforts to be more accessible in the way they distribute information. Here is their statement, from UN.org:
In order to make information on the United Nations and its activities available to the widest range of audiences, and in keeping with resolutions of the General Assembly, the Department of Public Information (DPI) is actively pursuing accessibility of the United Nations website by persons with disabilities. The objective of DPI is to comply with the Web Content Accessibility guidelines of the World Wide Web Consortium standards, which at the present time are the only standards with worldwide recognition.
The Accessibility Guidelines for United Nations Websites contains many helpful examples of accessibility remediation. Additionally, its landing page allows visitors to experience an inaccessible website from the perspective of someone with a disability.
