Ocean acidification is directly caused by climate change and represents a direct threat to the marine resources such as coral reefs and sea shells. It also has direct and indirect impacts on Pacific island coastal and pelagic ecosystems.

The SPREP assists countries in developing national adaptation plans and other climate change policies, and is dedicated to coordinate the regions response to climate change.

For that purpose Monaco supports SPREP to build coastal communities resilience to ocean acidification through the Pacific Partnership on Ocean Acidification project.
Monaco commits financially support this integrated approach in favor of ocean acidification monitoring, strategies to strengthen the resilience of local communities, and concrete actions to adapt to and mitigate ocean acidification.
The Partnership with the SPREP seeks to achieve outcomes through three outputs and associated actions:
 Assessment of regional vulnerability to ocean acidification, research and ecosystem monitoring data to inform policy and adaptation;
 Practical adaptation actions identified and carried out in pilot project areas ;
 Ensure that Pacific islands capacity is built to understand and adapt to ocean acidification as well as help raise awareness on this issue.
