ACCA SBR 2026: How to Answer the New IFRS S1 & S2 Sustainability Question

IFRS S1 and S2 are new to SBR, and they are not optional. If a climate question lands in your 50-mark scenario, describing what sustainability reporting is will score close to nothing. The marks are for applying the standards to the company in front of you.

Why this topic trips students up

IFRS S1 (general sustainability disclosures) and IFRS S2 (climate) entered the SBR syllabus with no prior exam history to lean on. They can appear inside the big 50-mark Section A question, sitting right next to a consolidation or a financial instruments issue. You have to move between traditional IFRS and sustainability in the same answer.

The December 2024 examiner report was blunt about the first attempts: answers were "disappointing," with many candidates simply describing materiality under the sustainability standards rather than applying it. The examiner put it down to a plain lack of preparation for the topic. That is the whole problem in one sentence — students revise the definitions and skip the application.

What the standards actually require

IFRS S1 is built on four pillars: governance, strategy, risk management, and metrics and targets. Learn those four words — they are the skeleton of almost any sustainability answer. IFRS S2 applies the same structure to climate specifically, and this is where marks are won or lost.

S2 demands disclosure of Scope 1, 2 and 3 emissions — and Scope 3 (the value chain) is the one candidates forget, despite often being the largest and riskiest. It also requires both physical and transition risks: describing floods and heat while ignoring policy, carbon pricing and technology shifts is only half an answer. And risks must be assessed over short, medium and long-term horizons, not a single snapshot.

Worked example: same question, two answers

Requirement: Explain how the entity should disclose its climate-related risks under IFRS S2.

Wrong answer (scores ~0): "The company faces climate risk and should be transparent. It should disclose its carbon emissions and explain the risks to investors so they can make decisions."

Answer that scores: "The entity must disclose Scope 1, 2 and 3 emissions; Scope 3 is significant here because manufacturing is outsourced across the value chain. Disclosing only physical risks (flooding at the coastal plant) is insufficient — transition risk from the proposed carbon tax could impair the asset within the medium term. These disclosures matter because climate exposure affects the entity's enterprise value, which is what the standards are designed to help investors assess."

Same knowledge. The second names the scenario, splits physical from transition, flags Scope 3, and links back to enterprise value. That link — disclosure to investor decision-making — is what separates a pass from a fail on this topic.

What to do before your sitting

First, memorise the four S1 pillars and force every sustainability answer into that structure — it stops you rambling and guarantees breadth. Second, for any climate scenario, always write both a physical and a transition risk, and check whether Scope 3 is being ignored. Third, end each sustainability point with "…which affects enterprise value because…" — if you can't finish that sentence, you're describing, not applying.

Bottom line

SBR's global pass rate sits around 50%, and sustainability is the newest, least-prepared corner of the syllabus — which means it's where the easy marks are hiding for anyone who does the application work. Don't tell the examiner what IFRS S2 is. Tell them what it means for this company.
