Sustainable Coastlines Hawaii is a grassroots nonprofit in Honolulu focused on environmental care.

Sustainable Coastlines Hawaii is a grassroots, local nonprofit organization operating primarily on Oahu. Established in 2010 by eight friends, the organization works to inspire communities to care for their local environment and coastlines. Their activities range widely from waste diversion and public awareness campaigns to fun, hands-on beach cleanups. In addition to community cleanups, the group runs educational programs and team-building corporate cleanups designed to beautify coastlines and encourage better consumer behavior. Individuals interested in volunteering with Sustainable Coastlines Hawaii can get involved by joining one of their scheduled cleanup events.
