The spatial target of 125,000 km2 was calculated based on the global dataset developed by the World Resource Institute (WRI) estimating a total global coral reef area of 249,713 km2. This dataset has a resolution of 500m is widely used for other global products (e.g., GCRMN, TNC Mapping Ocean Wealth explorer platform).
The choice of securing 50% of the global coral reef area was based on Target 3 of the Kunming-Montreal Global Biodiversity Framework that calls for the effective conservation and management of at least 30% of terrestrial and inland water areas, and of marine and coastal areas. With coral reefs projected to the ecosystem most at risk of collapse in the face of climate change, and an estimate from the UNEP-WCMC that ~60,000 km2 of coral reefs are under protection, experts agreed that this Coral Reef Breakthrough should make the ambitious statement to secure at least 50% of global coral reefs by 2030.
The funding target was calculated based on “The cost of saving our oceans – estimating the. Funding gap of sustainable development goal 14” study published by Johansen and Vestvik (2020) evaluating the costs of meeting SDG14 at USD 174.5 billion/year (7), and widely used to describe the funding gap in ocean conservation (8). The Coral Reef Breakthrough funding target of USD 12. billion was calculated as 1% of that target for 7 years (2023-2030) on the basis that coral reefs cover ~1% of oceans.
The International Coral Reef Initiative (ICRI) and the Global Fund for Coral Reefs (GFCR) are co-leading the Coral Reef Breakthrough process with the High-Level Climate Champion Team, with support from Sweden and Monaco
