The International Alliance to Combat Ocean Acidification works with national, regional, and subnational governments to:

(1) Elevate urgency and ambition for climate action.

(2) Integrate ocean into climate dialogues and policy frameworks.

(3) Facilitate greater knowledge of ocean acidification and encourage policy actions by governments

The OA Alliance was launched in 2016 by the four North American West Coast governments of California, Oregon, Washington and British Columbia, Canada in direct response to the observed impacts of ocean acidification on oyster hatchery production across the North American West Coast during the mid-2000s.

Today, the OA Alliance is comprised of over 100 members, including 13 national governments, 9 states, 2 provinces, 6 tribal and sovereign nations, and 4 cities, along with local research institutions, monitoring networks, businesses, affected industry partners and NGOs.

The rapid growth of the OA Alliance confirms the desire of policy and decision-makers to better understand climate impacts to marine resources and to implement actions that reduce impacts and build resiliency.
