Coral Reef Biodiversity Credits
and Nature Markets

The Coral Reef Biodiversity Credits project aims to develop a high-integrity quantitative biodiversity accounting methodology for coral reefs that is broadly applicable and accessible. It is intended drive the development of emerging marine biodiversity credit markets and investment in reef restoration initiatives.  

Reef restoration and adaptation technologies, like those developed under RRAP, are advancing rapidly. Yet, there remains a major financing gap for large-scale implementation. According to the World Economic Forum, the global funding need for achieving Sustainable Development Goal 14 (life below water) is estimated at approximately US$175 billion annually, with less than US$10bn actually being spent. Addressing the gap requires new financing mechanisms that can mobilise investment into reef protection and restoration at scale, while delivering measurable ecological and social outcomes. 

Led by the Great Barrier Reef Foundation in partnership with the Australian Institute of Marine Science, this work aims to establish a scalable, science-based methodology that enables the monitoring and reporting of positive biodiversity outcomes resulting from reef restoration activities, and can underpin their monetisation. It is intended to provide a streamlined pathway towards sustainable financing, including for Traditional Owners and reef communities in Australia, the Pacific and beyond.

Scope

In supporting the development of high-integrity Coral Reef Biodiversity Credits, the methodology aims to align with global biodiversity accounting and environmental markets frameworks. The project will:  

  • Develop a robust quantitative methodology for assessing coral reef biodiversity using a basket of appropriate indicators 
  • Provide guidance on monitoring and measurement approaches to underpin the method 
  • Model how coral conservation and restoration activities can generate biodiversity benefits 
  • Leverage the accounting approach to develop biodiversity crediting pathways aligned with global standards for emerging nature markets and crediting frameworks 
  • Provide decision-support tools for reef managers and restoration practitioners 
  • Integrate with the Pilot Deployments Program to test the draft methodology in the field
