Each organization featured under the Big Green Tent is reviewed by a council of Expert Vetters (EVs) with at least 100 years of combined experience, ensuring credibility and impact.
Ever wanted to give to environmental action but weren’t sure where your money is really needed? We make it simple. Choose outstanding organizations and give with confidence.
Vetting Process
Every organization featured under The Big Green Tent is reviewed by a council of experts who work directly in the same field as the group they are evaluating—whether that’s forest conservation, renewable energy, or environmental justice. Together, these specialists bring over 100 years of combined experience to the table, ensuring that every organization we spotlight is credible, effective, and worth your support. This isn’t just a seal of approval—it’s a deep dive into what makes grassroots solutions work.
We believe vetting should be transparent and collaborative. Our experts share their reasoning in our newsletter, answering your climate questions and explaining exactly why they chose each organization. You get a front-row seat to their decision-making process and learn from the best in the field. We also involve emerging leaders in this work, pairing them with seasoned experts to build the next generation of sustainability leadership. If you are an expert in the climate space, join our vetting community and help shape the future of environmental action.
Donation Process.
Giving through The Big Green Tent is simple, secure, and designed for flexibility. In partnership with EarthShare—a trusted organization with over 35 years of experience managing environmental giving—we offer users their own Donor Advised Fund (DAF). This means you can contribute tax-deductible funds now and distribute them later to the vetted organizations of your choice, as you read and learn their stories.
This model turns passive reading into active participation. Instead of one-time gifts, donors build ongoing relationships with grassroots change makers worldwide. Every donation supports work that has been carefully reviewed by experts, ensuring your generosity fuels real impact. With The Big Green Tent, every gift becomes part of a shared journey toward a livable planet.
