Oceans 5

Oceans 5 (O5) is the world’s leading funders’ collaborative dedicated to ocean conservation. Founded in 2011 it now includes nearly 30 donor organisations that provide over $20 million annually into a pooled fund, which supports organisations working in all five oceans. Since its inception, O5 has provided over $150m in grants and supported over 130 projects in more than 90 countries and regions. 

Oceans face accelerating threats from overfishing, climate change, and biodiversity loss, with illegal and unregulated fishing undermining marine ecosystems and food security. Global commitments such as protecting 30% of the world’s oceans by 2030 require coordinated international action. By aligning donors and organisations around shared priorities like marine protected areas and sustainable fisheries management, O5 amplifies impact and strengthens the collective voice of ocean advocates with governments worldwide. 

The ERF grant is contributing to O5’s pooled fund, supporting its portfolio of high-impact initiatives. This includes expanding marine protected areas, tackling illegal fishing, advancing technology for monitoring and enforcement, and building scalable models for small-scale fisheries.
