About Us

The International Alliance to Combat Ocean Acidification (OA Alliance) brings together governments and organizations from across the globe dedicated to taking urgent action to protect coastal communities and livelihoods from the threat of ocean acidification and other climate-ocean impacts.

Together, OA Alliance members are:

(1) Elevating urgency and ambition for climate action by highlighting impacts to ocean resources, ecosystems and communities.

(2) Integrating ocean into climate commitments, policies and multi-governmental frameworks.

(3) Translating knowledge into policy actions by national, regional and subnational governments

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

Members of the OA Alliance are helping to promote and drive implementation of actions, including nature-based solutions, that address the causes of ocean acidification and increase biodiversity, adaptative capacity and resiliency of coastal communities.

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

Recognizing that climate-ocean impacts are an immediate and critical threat to coastal communities and livelihoods, these subnational leaders were inspired to build a robust global network elevating the urgency for climate action and to help drive policy action.

The OA Alliance calls for the creation of OA Action Plans that will:

  • Reduce atmospheric carbon dioxide emissions, the number one cause of ocean acidification
  • Advance scientific understanding of climate-ocean impacts
  • Reduce local pollutions that exacerbate ocean acidification
  • Protect the environment and coastal communities from climate-ocean impacts
  • Expand public awareness
  • Sustain international and multi-governmental support for addressing this global problem

The OA Alliance has grown to over 100 members representing a wide diversity of national, state, municipal, and sovereign tribal, indigenous, and First Nation governments along with many dedicated affiliate partners like NGOs, seafood industry leaders, and local academia.
