The University of Oxford team introduced a conceptual framework for assessing comparability of tools for corporate biodiversity impact accounting. They applied the framework to twenty widely used tools and showed how currently available tools are concentrated on certain aspects of biodiversity, particularly species composition and ecological condition/integrity. This paper explains the analysis done and discusses how the findings may concentrate and disperse capital flows towards certain companies, and also with an impact on effectiveness at supporting businesses' nature-positive journeys.
The research team argues that establishing comparability can help align corporate biodiversity disclosures, facilitate investor decisions, and better support the implementation of Target 15 of the Kunming-Montreal Global Biodiversity Framework.
