The Jewish Green Business Network connects North American and Israeli green business professionals in order to accelerate climate solutions across the Jewish world and beyond.
Many of us are living with intense anxiety amid the recent Iran attacks against Israel, political violence, antisemitic acts, and the climate crisis.
Adamah’s core value of Jewish Peoplehood, building bridges for the Jewish people—from Israel and the Diaspora—to build a more sustainable future together, is more important now than ever. We stand with all those who yearn for peace and pray for the safety of innocent victims of violence.
In this moment, we need to mobilize the full power of the Jewish people in the face of existential crises. We need all hands-on deck to find our way through this moment, for our people and our planet—and that must include the tremendous brilliance, innovation, resourcefulness, and strength of the Jewish green business demographic.
That’s why we are excited to launch the Jewish Green Business Network, a new Adamah program with massive impact potential moving forward. We are deeply grateful to our friends at the Jewish Climate Trust for believing in Adamah and in the power of this vision.
What will the Jewish Green Business Network do?
- Local gatherings, business tours, climate week events, career panels, and networking events
- A supportive multi-generational community of Jewish professional leaders driving innovation, and showing up to share, learn, mentor, and collaborate with one another
- Unique opportunities for business development, partnerships, and strategic connections between the North American and Israeli green business worlds

And here’s to the great strength of the Jewish people, and the power of community to see us through difficult times.
B’Shalom,
