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 thriving natural systems 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.
