Mission & Focus Areas
Woodwell’s stated mission is to conduct science for solutions at the nexus of climate, people, and nature, partnering with leaders and communities for meaningful impact on the climate crisis. Its stated research areas include the land-climate connection: how land use affects the climate, how climate change alters forests, ecosystems, and agriculture, and how land management may help slow climate change. The organization also describes work on climate risks and climate-relevant ecosystems, including Arctic permafrost and tropical forests.
In its own descriptions of its programs, Woodwell identifies policy-relevant research, policy engagement, education and communication, and center-funded science. The Fund for Climate Solutions is described as a way to seed, extend, or scale projects, support follow-up research, and help startup projects demonstrate proof of concept.
