Who we are

Mosaic is a new national initiative to better support people working to deliver clean air and water, a stable climate, healthy and just communities for all, and protection of our natural heritage by bolstering the critical infrastructure all movements need to succeed.

Mosaic invests in field-wide connections and shared resources that enable people and organizations to work together, like communications, advocacy tools and training, leadership development, field knowledge, backbone services, and networks. A diverse Governance Assembly that includes a super-majority of NGO and grassroots representatives, working together with funder participants, leads Mosaic and makes grant decisions.

Mosaic is a fiscally sponsored project of the Windward Fund, led by a diverse constellation of leaders from the environmental field and supported by a small staff.
