Was the ISSB's April 22 decision in Beijing — to advance nature-related disclosure requirements as an IFRS Practice Statement rather than a binding standard — a step back? That's how the news was widely read. Non-mandatory. Soft form. A bit anticlimactic, especially for those who had been pushing for a standalone nature standard. I read it differently. The ISSB isn't softening on nature. It's deciding the sequencing.

What was actually decided in Beijing

On April 22, the International Sustainability Standards Board met in Beijing with nature-related disclosures on its agenda as an independent item. The papers covered location-specific information, engagement with Indigenous Peoples and local communities, and — in staff paper AP3D — the question of what form the standard-setting should take.

AP3D laid out four options: amend IFRS S1, amend IFRS S2, issue a new standalone ISSB Standard, or publish an IFRS Practice Statement. Staff recommended the fourth. The Board agreed. An exposure draft is due in October 2026, timed to COP17.

The civil-society reaction focused on the form. Several groups had urged a binding standard ahead of the meeting and were disappointed by what looked like the lightest of the four options.

Why I read this as sequencing, not retreat

Heavy issues don't move into practice by being mandated outright.

Nature is broader than climate, more location-specific, and the underlying corporate data infrastructure is far less mature. Drop a binding new standard onto that — on top of jurisdictions still implementing IFRS S1 and S2 — and you risk fracturing the platform you're trying to extend. AP3D itself, the staff paper, is unusually candid about this. The recommendation rests on giving nature visibility and prominence while keeping S1 and S2 untouched at this stage, and prioritizing implementation support over building out new thematic architecture.

That isn't a retreat. It's the order-of-operations of an institution that wants the underlying platform to hold while a heavier topic is integrated into it.

I'd put it this way: the question of whether nature belongs inside investor-facing disclosure has already been settled. The April decision was about how to land it without breaking what's already in flight.

Form is soft. Substance is not.

Here's where the "non-mandatory" framing gets misleading.

AP3D makes explicit that the substantive content — the actual disclosure requirements and guidance on nature — would be the same regardless of which of the four forms was chosen. The form decision is about where to put it, not what to put in.

The ISSB went further in its public communications. Chair Emmanuel Faber, in announcing the decision, was direct: providing material nature-related disclosures is not optional, because IFRS S1 already requires it. The Board's official position is that for entities that apply the Practice Statement, doing so would have the full effect of applying an ISSB Standard.

In other words: the form is non-binding. The disclosure obligation it operationalizes is not.

The form is soft. The substance is not.

Why "mandatory or not?" is the wrong first question

In corporate practice, the first question is almost always: is this mandatory or not?

It's a fair question. But in disclosure, it's often the wrong first one.

Markets move ahead of regulation. Investor expectation moves ahead of markets. And corporate practice tends to move ahead of expectation, at least in companies whose boards are paying attention to where the regulatory tide is going. Treating "Practice Statement, therefore not yet" as the answer assumes regulatory force and market relevance move at the same speed. They rarely do.

The ISSB's project page is worth noting here. Nature-related Disclosures has already moved out of the research phase and into standard-setting. Its scope is not limited to a particular nature topic — it covers all nature-related risks and opportunities that could reasonably be expected to affect a company's prospects. The March 2026 meeting advanced work on metrics, transition plans, targets, and how nature-related disclosures interact with international agreements and regulation. None of this looks like an institution stepping back.

The architecture question underneath

What I find more telling than the form question is what the institutional design suggests about how nature is being positioned.

A great deal of corporate disclosure today still treats climate as the main line and nature as a separate exhibit. Climate sits inside strategy, capital allocation, and risk management. Nature sits in a biodiversity-initiatives section, often closer to the back of the report. There are legitimate reasons for this — capacity constraints, prioritization, sequencing decisions internal to the company — and I don't underestimate them. From the inside of a reporting team, those constraints are real.

But the ISSB's architecture isn't tracking that split. Nature is being positioned as investor-facing disclosure that complements S1 and S2 — inside the spine of the disclosure framework, not as a separate exhibit alongside it.

If that read is right, the question being asked of companies is no longer "have you added a nature item?" It's whether the disclosure architecture itself — the strategy disclosure, the risk-management disclosure, the metrics, the targets — is built in a way that can carry nature when it has to. Not as an additional topic. As a structural property of the framework already in use.

What the signal actually is

The reason ISSB didn't reach for a binding standard isn't that nature is light. It's that nature is too heavy to land cleanly without protecting the platform underneath it. So the form chosen is soft, and the substance underneath it is not.

The signal from Beijing is not "nature can wait." The signal is that nature is being absorbed into the mainstream of investor-facing disclosure — and that the question for companies has shifted. It is no longer about adding something on nature. It's whether the disclosure architecture they already have can reach far enough.

That's a question of structural design, not of topic coverage. And it's one I'd expect to start showing up in investor conversations long before the exposure draft closes.
