The Need

“Our oceans sustain jobs, support coastal economies and feed billions of people.  At the heart of protecting our oceans is the imperative to significantly reduce the world’s emissions of carbon dioxide. We must lead together to secure the health of the oceans, and our economies and communities that depend on this vital resource.”
Jay Inslee

Governor, Washington State, USA


increase in ocean acidity due to increased carbon emissions.

Ocean acidity has already increased by 30 percent and is expected to double over pre-industrial levels by the end of this century as a result of the ocean absorbing one-third of the atmospheric carbon dioxide generated by human activities. Significant adverse impacts on fisheries and marine ecosystems have already been documented due to ocean acidification and these impacts will worsen in the future.
To protect our oceans, it is imperative that we significantly reduce carbon dioxide emissions across the world. Indeed, science indicates that we can avert a larger crisis if we act immediately to reduce carbon emissions. In 2015, 195 countries signed the historic Climate Agreement in Paris committing to meaningful and timely action to reduce greenhouse gas emissions. The world’s nations and subnational governments must succeed in reducing emissions in order to protect the health of the oceans and other natural systems on which the planet depends.

Working to halt the progress of ocean acidification and manage its impacts on our coastal communities, economies and ecosystems requires new focus, new investments, increased partnerships and a commitment to immediate action.

In joining the Alliance, governments and affiliated partners will endorse a Global Call to Action and will commit to taking to taking actions that address the environmental and economic threat posed by ocean acidification within their region by creating their own unique OA Action Plan.
