Which organization functions as a nonprofit public interest organization that promotes collaboration among regional government organizations?

The National Association of Regional Councils (NARC) serves as a nonprofit public interest organization specifically designed to facilitate collaboration among regional government organizations. NARC's primary role is to represent the interests of regional councils across the United States, advocating for policies that improve regional planning, economic development, and transportation. By bringing together diverse stakeholders, NARC fosters communication and coordination among regional councils, thereby enhancing their ability to address common challenges and develop effective solutions.

This collaboration is essential because regional councils often deal with complex issues that require coordinated efforts across various government entities, nonprofit organizations, and private sectors. NARC provides the platform for sharing best practices, resources, and experiences among its members. This not only strengthens the regional councils but also improves their effectiveness in serving their communities.

The other organizations mentioned may not have the same scope or focus as NARC, which is explicitly dedicated to the objectives of regional councils and promoting their collaboration.
