California’s Ocean Acidification Action Plan

Reading time: 3 minutes
19 June 2019

Global carbon emissions are driving changes not only to the Earth’s climate, but also to the chemistry of the world’s oceans. The oceans are acidifying because they are absorbing a significant share of the carbon dioxide (CO2) released primarily by the burning of fossil fuels and changing land uses.

Ocean acidification (OA) is accelerating rapidly, with enormous implications for the health and productivity of California’s coastal and ocean ecosystems and the communities and industries that depend on them, including California’s ocean-based economy.

In 2016, California co-founded the International Alliance to Combat Ocean Acidification (OA Alliance), an initiative that is helping to grow scientific knowledge about impacts of ocean acidification and transforming it into increased urgency and ambition for climate mitigation and visible and innovative regional actions. Through this effort, national, subnational, regional and tribal governments are proactively responding to the impacts of ocean acidification as they chart “OA Action Plans” for their regions.

California’s OA Action Plan lays out six strategies and related actions to identify and reduce the causes of OA, improve the resilience of vulnerable groups, and minimize harmful effects; you can find out more in the case study

This case study is part of a series from our Policy Action work, which aims to accelerate the pace of climate policy development and adoption in states and regions. To see more innovative climate policies from around the world, check out our Policy Action Map.
