Johnson is active in environmentalism and sustainability, often with a focus on the world's oceans. Johnson and his wife Kim created the Johnson Ohana Charitable Foundation and the Kōkua Hawaii Foundation. In 2008, Johnson adopted the concept of greening (reduce and reuse), and donated 100% of the proceeds of the Sleep Through the Static tour to the Johnson Ohana Charitable Foundation. Similarly, the proceeds from the 2010 To the Sea album tour went to All at Once, a Johnson-backed collaboration of greening charities promoting fan involvement.
