Biodiversity loss is now recognised alongside climate change as one of the defining systemic risks of our era. The Taskforce on Nature-related Financial Disclosures (TNFD) — finalised in 2023 — provides the framework for organisations to assess, disclose and ultimately act on their nature-related dependencies and impacts.
What TNFD actually asks of organisations
TNFD follows a LEAP approach: Locate your interface with nature, Evaluate your dependencies and impacts, Assess your risks and opportunities, and Prepare to respond and report. Each step requires both qualitative judgement and — increasingly — quantitative data on biodiversity metrics such as species abundance, habitat integrity and ecosystem service values.
Biodiversity quantification in practice
Quantifying biodiversity impact is more complex than carbon accounting. There is no single universal metric equivalent to CO2e. Instead, practitioners work with a suite of indicators — mean species abundance, potentially disappeared fractions of species, biodiversity footprint metrics — that must be selected based on sector, geography and data availability.
