In 2010, Alaska Clean Harbors launched a statewide effort to curb harbor pollution. 15 years later, 11 harbors were engaged in the program, helping protect coastal waters

Alaska Clean Harbors is a voluntary statewide program that works with harbor managers, communities and boaters to prevent pollution and reduce waste in Alaska's harbors and marine areas.

As of November 2025, 11 harbors were engaged in the program. Four had achieved certification, three were working toward certification and four had expressed interest.
