Become a Sponsor
Align Your Brand with a Thriving Future
We love our partners. Sponsorship with the Alliance isn’t just philanthropy — it’s a meaningful collaboration. Together, we’re co-creating resilient communities, healthy watersheds, and vibrant local economies.
When your company or organization supports our work, you’re not just funding events — you’re investing in long-term ecological health, youth leadership, and community-powered solutions.
Why Sponsor the Alliance?
Mission Alignment
Support climate resilience, environmental justice, youth empowerment, and regenerative practices — in action, not just in name.
Tax-Deductible Giving
As a nonprofit initiative, all monetary and in-kind sponsorships are tax-deductible. We'll provide documentation for your records.
Audience Engagement
Reach deeply connected, values-driven communities in Connecticut and beyond — including educators, families, artists, environmentalists, and youth leaders.
Storytelling Opportunities
We love telling stories. Sponsors receive shout-outs in event promotions, and we’re happy to collaborate on stories, photos, and videos that show your impact in real life.
