Our PeopleÂ
The Community
Community is so foundational at Common Earth that we focus first on our broader community rather than on our core team, as you might expect. Ours is comprised of thoughtful people from around the world passionate about understanding the complexities of climate change and how we can move toward a post-carbon, caring society globally. A shared understanding and language are built through participation in the courses and are expanded upon through activities and in an online forum where people can collaborate and support one another.

In 2020 Sarah joined David in his efforts to create a space where people can grapple with how we can move to a post-carbon caring society.

When not working on Common Earth efforts, you can find her reading or on her bike. She and her husband believe strongly in the power of community and love nothing more than hosting the many friends and family they share. Sarah is still in awe of the overlap that is occurring and the fact that so many of her Common Earth connections have become her family.
