Green Infrastructure Collaborative
On October 8, 2014, EPA joined with other federal agencies, nongovernmental organizations, and private-sector entities to form the Green Infrastructure Collaborative, a network-based learning alliance created to help communities more easily implement green infrastructure.
The Green Infrastructure Collaborative Statement of Support outlines commitments from members to advance adoption of green infrastructure to support water quality and community development goals. The collaborative will build capacity for implementing green infrastructure practices by providing a platform for national stakeholders to:
- Leverage joint efforts to publicize the multiple community benefits of green infrastructure,
- Build and share knowledge around emerging green infrastructure technologies and policy issues, and
- Facilitate shared inquiry into the best ways to encourage adoption of green infrastructure technologies at the community level.
Collaborative members plan to work closely together to align public and private knowledge and resources to promote green infrastructure. They will highlight the broad community benefits of green infrastructure including improving air quality, reducing energy use, mitigating climate change, and increasing resilience to climate change impacts.

A Federal Letter of Support for the Green Infrastructure Collaborative was released by seven federal agencies. Each agency is committed to taking specific actions to promote green infrastructure. Joining EPA, the cooperating agencies are the:
- U.S. Department of Agriculture,
- U.S. Department of Defense,
- U.S. Department of Energy,
- U.S. Department of Housing and Urban Development,
- U.S. Department of the Interior, and
- U.S. Department of Transportation.
The Green Infrastructure Collaborative includes more than 20 academic, nongovernmental, and private sector organizations committed to advancing the implementation of green infrastructure strategies.

The Green Infrastructure Statement of Intent signed in 2007 established an initiative to promote and encourage the use of green infrastructure. The partners that signed the statement were EPA and the:
- National Association of Clean Water Agencies,
- Natural Resources Defense Council,
- Low Impact Development Center, and
- Association of State and the Interstate Water Pollution Control Administrators (now the Association of Clean Water Administrators).
American Rivers, the Water Environment Federation, and the US Water Alliance joined the partnership after the original signing. The Green Infrastructure Collaborative builds upon activities associated with that initiative, with members working together and sharing resources, tools, and research to advance green infrastructure implementation. Learn more about collaborative members in this section and the resources they are contributing to the effort.
Founded in 1973, American Rivers Exitis a conservation organization centered on protecting and restoring America's rivers and streams. American Rivers is a strong supporter of moving the focus from gray to green infrastructure.

The National Association of Clean Water Agencies (NACWA) Exit has been at the forefront in advocating the use of green infrastructure to address the nation's clean water challenges resulting from wet weather. NACWA regularly engages with Congress to promote green infrastructure applications for wet weather management and secure greater investment in water infrastructure.
The Natural Resources Defense Council (NRDC) Exit is one of the nation's largest environmental stakeholder groups and is a staunch supporter of green infrastructure. Their website includes a variety of reports, fact sheets, and case studies on the use of green infrastructure to protect and restore our nation's waters.
