Nature Reporting
TNFD and nature reporting: what's coming for UK SRS
The Taskforce on Nature-related Financial Disclosures (TNFD) is the leading global framework for reporting nature-related risks and opportunities. Currently voluntary and not part of UK SRS, nature is widely seen as the next frontier following the ISSB's announcement to build nature standards.
What TNFD is
TNFD published its disclosure recommendations to give companies and investors a consistent way to assess and report their dependencies and impacts on nature 13. Its method is the LEAP approach — Locate, Evaluate, Assess, Prepare — and its disclosures follow the same four pillars as climate reporting: governance, strategy, risk and impact management, and metrics and targets 13. Adoption has scaled quickly: by late 2025 the TNFD reported 733 organisations had committed to its recommendations, representing over US$9 trillion in listed-company market capitalisation and more than US$22 trillion in assets under management 13.
TNFD, TCFD and the ISSB
TNFD did for nature what TCFD did for climate, and it is now following the same trajectory. TCFD was absorbed into the ISSB in 2023 12; in November 2025, drawing on its Biodiversity, Ecosystems and Ecosystem Services research, the ISSB announced it would undertake nature-related standard-setting using the TNFD framework as a basis 14. The options range from a dedicated nature standard to incremental additions to IFRS S1 and S2 with supporting guidance 14.
The roadmap
The ISSB is targeting a nature-related exposure draft to coincide with the Convention on Biological Diversity COP17 in October 2026, with a final standard likely in 2027 14. The TNFD, for its part, expects to complete its in-progress technical work — including additional sector guidance — by Q3 2026, then pause new guidance to support the ISSB's programme 14.
What this means in the UK
This is the crucial point for UK companies: new or amended ISSB standards — whether on nature or human capital — do **not** automatically apply in the UK. They must first pass through the UK's formal endorsement process before they can be incorporated into UK SRS 15. So nature reporting is coming to UK SRS, but indirectly and on a later timeline than climate. In the meantime, UK SRS S1 already requires disclosure of *any* material sustainability matter that could affect enterprise value — which can include nature-related risks where they are material 3.
What to do now
Because nature data has a long lead time, companies exposed to nature-related risk benefit from starting early — mapping dependencies and impacts using the LEAP approach, even while formal UK requirements are still forming 13. This mirrors the lesson from Scope 3: the data groundwork takes far longer than the rule-making. Companies should consider nature-related risks alongside their existing statutory biodiversity duties but keep corporate disclosure separate from planning obligations.
