The support for 50 Reefs is led by Bloomberg Philanthropies with The Paul G. Allen Family Foundation and The Tiffany & Co. Foundation.

These three foundations have joined forces to tackle the desperate need to protect coral reefs. They bring the perfect combination of government, business, and science and technology expertise needed to address this important issue. 


Founder Michael R. Bloomberg is a leading funder in ocean conservation through the Vibrant Oceans Initiative, which aims to reverse declining fish supplies, and the 50 Reefs initiative to save coral reefs. Bloomberg Philanthropies works in more than 120 countries around the world to ensure better, longer lives for the greatest number of people. The organization focuses on five key areas for creating lasting change: arts, education, environment, government innovation, and public health. 

Launched by Microsoft co-founder and philanthropist Paul G. Allen and Jody Lynn Allen in 1988, the Allen family's philanthropy is dedicated to transforming lives and strengthening communities by fostering innovation, creating knowledge and promoting social progress. Since inception, the Foundation has awarded over $550 million to more than 1,400 nonprofit groups to support and advance their critical charitable endeavors in the Pacific Northwest and beyond. The Foundation's funding programs nurture the arts, engage children in learning, address the needs of vulnerable populations, advance scientific and technological discoveries, and move new knowledge to global impact that creates economic growth and societal benefit.

Established in 2000, The Tiffany & Co. Foundation provides grants in environmental conservation, working to preserve the world's most treasured landscapes and seascapes. The Foundation's programs promote responsible mining, healthy marine ecosystems and the enhancement of urban environments through strategic design improvements in new and existing parks. 

Without coral reefs, we could lose up to a quarter of the world’s marine biodiversity and hundreds of millions of the world’s poorest people would lose their primary source of food and livelihoods. We must not allow this to happen.
