Who We Are

Dayenu is a movement of American Jews confronting the climate crisis with spiritual audacity and bold political action. We care deeply about equity and justice in our world and about the future we create for our children and future generations. We believe that together, drawing from our Jewish tradition, experience, and faith, we have the power to create real and lasting change.

Join us in saying:

Dayenu: We have had enough!

But we also have enough. We have what we need to transform our world.

Our Mission

To secure a livable and sustainable world for all people for generations to come by building a multi-generational Jewish movement that confronts the climate crisis with spiritual audacity and bold political action.

Our People

Dayenu is building a dynamic, multi-generational movement of American Jews courageously confronting the climate crisis. We are adults, and we are teenagers. We are professionals, and we are students. We are parents, and we are retirees. We are long time climate activists, and we are people increasingly concerned and wondering what we can do about the climate crisis. Some of us draw strength from Jewish teachings and our spiritual roots. Some of us are simply seeking meaningful ways to act.

Grassroots leadership is the engine that drives our work. Through a growing network of Dayenu Circles across the country, we’re gathering, training, and taking action to advance bold solutions to the climate crisis. Learn more about Dayenu Circles here →

Dayenu partners closely with other organizations and efforts — within and beyond the Jewish community — to help bring the full strength and voice of the American Jewish community to national and global movements. We also work arm in arm with communities that are directly impacted by, and most vulnerable to, the climate crisis. Learn more about Dayenu’s allies and partners here →
