Why M40?

Mangrove ecosystems are recognised as a powerful nature-based solution for climate mitigation, coastal resilience and sustainable livelihoods. However, investing in mangroves as an asset has remained elusive. 50% of all mangroves globally have been lost. The remaining mangroves are located in 700+ regions around the world. Of these, the first 40 regions represent 70% of the world’s remaining mangrove ecosystems. 

These regions face many common challenges, including growing coastal cities, aquaculture and development. They all share the need to encourage investments in coastal economic development in balance with the protection and restoration of mangrove ecosystems. How can this be done? What investment examples can be mangrove-positive while creating sustainable economic activities? The Mangrove 40 (M40) explores the development of an investment platform that measures and recognises the various co-benefits provided by mangroves, establishing a global pipeline of projects and connecting them to private and public investors globally.

The M40 concept was developed and launched by Earth Security in 2020, combining analysis and the engagement of 130+ individuals and organisations working on mangroves and blue carbon. You can read more about Earth Security's original blueprint for the M40 here.
