IFRS S2 Does Not Require You to Have a Transition Plan
IFRS S2 requires disclosure of a transition plan if one exists, at paragraph 14(a). It does not require an entity to have one. The distinction changes who the real driver is.
This is the most common error in published commentary on IFRS S2, and it is an easy one to get right.
IFRS S2 does not require an entity to have a climate-related transition plan. It requires disclosure of the plan if one exists, at paragraph 14(a).
The word doing the work is “if”.
Why the distinction matters commercially
If you believe IFRS S2 mandates a transition plan, you will build one to satisfy IFRS S2. That produces a document written to a disclosure standard, aimed at a general audience of report readers, and tested against nothing in particular.
If you understand that IFRS S2 only asks you to disclose the plan you have, the next question becomes the useful one: who is actually asking us for a plan?
In practice the answer is one of:
- A prudential regulator. Most central bank requirements in this region are framed around climate risk management rather than transition planning as such, but the two overlap and supervisory expectations move.
- A lender or development finance institution. Facilities increasingly carry conditions, and those conditions are specific and testable.
- An index or rating methodology. Scored, weighted, and comparable against peers.
- A parent group or major shareholder. Often the most demanding audience, and the least visible from outside.
Each of these produces a different plan. A plan for a development finance lender needs to survive that lender’s own appraisal process. A plan for an index needs to hit specific scored criteria. A plan for a regulator needs to connect to the risk appetite framework and governance the regulator already supervises.
Knowing which one you are writing for is the difference between a document that does its job and a document that gets filed.
What paragraph 14(a) actually asks for
Where a plan exists, the disclosure covers the plan itself, the key assumptions used in developing it, and the dependencies it relies on.
The assumptions and dependencies requirement is the part that catches organisations out. A transition plan resting on grid decarbonisation at a particular rate, or on a technology becoming commercially available at a particular date, has to say so. That is uncomfortable, because it exposes how much of the plan is outside the entity’s control. It is also the honest position, and stating it is better than having a reader infer it.
The related error
A second, related mistake is describing the frameworks as though the bodies behind them still operate as they did. The Transition Plan Taskforce closed in October 2024 and GFANZ restructured in January 2025. We cover the current position in who owns transition plan guidance now.
Both errors come from the same habit: repeating framework descriptions written two or three years ago without checking whether they still hold.
What to do
- Do not tell your board that IFRS S2 requires a transition plan. It does not, and someone will eventually check.
- Identify the actual driver. Write it down. It determines the audience, the content and the test of adequacy.
- If a plan exists, disclose it properly, including assumptions and dependencies, rather than a summary that avoids the uncomfortable parts.
- If no plan exists, that is a legitimate position under IFRS S2 today. Whether it is a sustainable position depends entirely on who else is asking.
A caveat
Disclosure requirements and supervisory expectations both move. This reflects the position as at 28 August 2026. Confirm the current text of IFRS S2 and your own regulator’s expectations before relying on either.
How ESGweise helps
We work out who the plan is actually for before writing it, then build it to the current IFRS Foundation guidance with assumptions and dependencies stated openly. See our sustainability reporting and ESG strategy services, and our banking and financial services practice.

Frequently asked questions
Does IFRS S2 make transition plans mandatory?
No. IFRS S2 requires an entity to disclose information about its climate-related transition plan if it has one, at paragraph 14(a). The standard does not oblige an entity to prepare a transition plan. If no plan exists, there is nothing to disclose under that paragraph, though other disclosure requirements in the standard still apply.
What does IFRS S2 paragraph 14(a) actually require?
Disclosure of information about the entity's climate-related transition plan where one exists, including the key assumptions used in developing it and the dependencies on which it relies. The conditional framing is the important part: the obligation is to disclose the plan you have, not to have a plan.
If IFRS S2 does not require a plan, why is everyone building one?
Because something else is asking. In practice the driver is a prudential regulator requiring climate risk management, a lender or development finance institution making it a condition, an index or rating methodology scoring it, or a parent group requiring it. Identifying which of these is the actual driver matters, because it determines what the plan has to contain and who has to be satisfied by it.
Does this mean we can ignore transition planning?
No, and that would be the wrong conclusion. It means the reason for building one should be stated accurately. A plan built because a regulator requires climate risk management, or because a lender has made it a condition of facilities, is a plan with a real audience and a clear test of adequacy. A plan built because someone believed IFRS S2 mandated it often ends up written for nobody in particular.
