Many in philanthropy argue that there’s not enough time to overcome systemic barriers to engaging marginalized groups—and that even trying will slow down the process of reducing climate pollution. In fact, the exact opposite is true. Make multiyear, general support grants to community-based organizations that will be engaged in developing, financing, implementing, and communicating about clean energy and other climate justice projects. Support regional hubs and coordinated networks. Fund collaborations among partners taking transformative local solutions to scale.
