The world's biodiversity is in peril and its loss poses big financial risks to businesses and the global economy. More than half of the world's economic output — or about $44 trillion — is moderately or highly dependent on nature, according to the World Economic Forum. Moreover, the collapse of biodiverse ecosystems could hurt global GDP by $2.7 trillion annually by 2030, the World Bank warns in a new report.

Until recently, biodiversity loss was rarely viewed as a substantial risk to corporations. But that is changing and a new task force has been formed to help companies and financial institutions better understand the scope of the risk. The Task Force on Nature-related Financial Disclosures, or TNFD, aims to create a voluntary framework that companies can use to assess their nature-related risks and opportunities.

In this episode, we talk with Elizabeth Mrema, who is co-chair of the TNFD, about the goals of the task force, how she envisions them being implemented and how biodiversity is inherently linked to climate change.
