What does the ISSB's nature disclosure proposal mean for companies applying IFRS S1?

The International Sustainability Standards Board has proposed detailed nature related disclosures for companies applying IFRS S1. According to ESG News, the proposals target location and Indigenous communities. Feedback is open until 19 February 2027, and the source notes that the proposals do not yet have final status.

The emphasis on location is the practical headline. Nature related risks and dependencies are tied to specific places, so a disclosure regime that asks where a company operates and relies on natural resources pushes reporters toward site level and sourcing level data. That is a different data challenge from the corporate level aggregates many teams already compile for climate reporting. Indigenous communities are named explicitly in the proposal, which signals that the standard setter expects companies to consider people as well as ecosystems when they describe nature related matters.

For compliance teams, the nearest term task is deciding whether to respond to the consultation. The window runs until 19 February 2027, which leaves time to gather input from operations, procurement and legal functions. Teams that already apply IFRS S1 should map where their current disclosures touch on land use, water and biodiversity, because the proposal builds on the same standard. Procurement leads should note that location based disclosure tends to reach into supply chains, where raw material origin is often the least documented part of the picture.

The proposals are not final, so nothing here creates an immediate reporting obligation. The sources do not say when a final standard might be issued or which jurisdictions would adopt it. Professionals should therefore treat the consultation as an early look at direction of travel rather than a compliance deadline, while using the open comment period to shape what eventually lands.

The broader point is that nature is moving from a voluntary topic toward a structured disclosure subject. By building on IFRS S1 and naming location and Indigenous communities, the ISSB is asking companies to describe their relationship with nature in concrete, place based terms. Teams that begin collecting geographic and sourcing data now will be better placed when the standard is finalised.
