“Through SSDN, the City of Charlotte has been able to discuss overcoming obstacles to combat climate change with similar cities in population, area, and culture. We have utilized the group to build our expertise on different subjects and gain City support on initiatives that have been completed in other SSDN communities.”

Erika Ruane, City of Charlotte, North Carolina

"SSDN is an amazing resource for municipal sustainability professionals in the Southeastern US. SSDN provides beginning and experienced sustainability directors with access to collaborative learning opportunities, best practices in urban sustainability, and grant funding for city/county sustainability projects."

Peter Nierengarten, Sustainability Director, City of Fayetteville, Arkansas

“Through SSDN I was able to make personal connections with peers within our region. These connections are so important — whenever I need help, I am one email, one phone call away from my peers who are always so tremendously helpful. I love the SSDN annual meeting, where I meet with my counterparts from other cities/counties/states and learn more about their work, their challenges, and most importantly, identify opportunities where we can work together.”

Flavia Tonioli, Sustainability Manager, City of Miami Beach, Florida
