Regenerating nature requires an economic transformation. To halt and reverse biodiversity loss, we need to fundamentally transform the way we produce, use, and consume our products and food. Conservation and restoration efforts alone – crucial though they are – will not be enough. The circular economy offers a framework for such a transformation. Applied together, its three principles are able to help tackle the root causes of biodiversity loss and enable the regeneration of nature. These biodiversity benefits can be demonstrated across different industry sectors, as shown in this new study by Ellen MacArthur Foundation. This paper also highlights the key steps businesses and policymakers can take to scale the circular economy potential and help shape a nature-positive future.
