50 Reefs Initiative

A pioneering initiative identifying the coral reefs most likely to be key to saving the ecosystem.

What if we could identify the coral reefs most likely to survive climate change and protect them before it was too late?

We developed the 50 Reefs initiative while filming the Netflix Original Documentary, Chasing Coral. Our goal was to identify a global portfolio of fifty reef sites with the greatest potential to survive the impacts of climate change and enable reseeding surrounding reefs over time.

Published in 2018, the research offered a new approach to prioritizing coral reef protection, helping organizations, governments, and funders focus their resources where they could have the greatest impact.

The approach pioneered by 50 Reefs has transformed coral reef conservation. It has led to over $100 million in new conservation funding and continues to inform investment decisions around the world, including those by the Global Fund for Coral Reefs.

We developed 50 Reefs in partnership with the Global Change Institute at The University of Queensland and the Wildlife Conservation Society and was funded by Bloomberg Philanthropies, The Tiffany & Co. Foundation, and Paul G. Allen Philanthropies.
