Nature has moved from sustainability footnote to mainstream financial reporting — in roughly five years.
Over 620 organisations have committed to TNFD-aligned reporting. The EU’s CSRD ESRS E4 is now mandatory. The ISSB targets a nature-related exposure draft around CBD COP17 in October 2026. SBTi FLAG quantifies land emissions. IFC PS6 governs how project finance is underwritten on every continent.
For corporates, the question is no longer whether nature reporting will become mandatory, but which framework their company will be measured against, and whether the data infrastructure is in place when the auditors knock.
This series is a practitioner-grade walkthrough of the five most consequential pieces of the corporate nature-reporting stack. Each article opens with the numbers that matter, runs through the framework structure, and ends with how Climate Decode would actually deliver the work for a real engagement — not a generic explainer.
Read in order, or jump to the framework you need.
The articles build on each other — TNFD’s LEAP method drives FLAG’s footprint, which feeds IFC’s ESIA evidence, which lands in the EU’s ESRS E4 disclosure. But each one stands alone if you already know the rest of the stack.
