Climate has dominated the sustainability reporting conversation for years.
That is beginning to change.
The International Sustainability Standards Board is now moving towards formal proposals for nature-related disclosures. The work began around biodiversity, ecosystems and ecosystem services, but the direction is broader than biodiversity alone.
The focus is on how businesses depend on nature, how they affect it and how those relationships can create financial risks and opportunities.
That matters because nature is not a separate environmental issue sitting outside mainstream business reporting.
A food manufacturer depends on agricultural output and water availability.
A property developer depends on access to land and planning approvals.
A mining company can be exposed to water scarcity, habitat restrictions and rehabilitation obligations.
A retailer may depend on agricultural commodities produced thousands of miles away.
A pharmaceutical company may rely on natural resources within complex global supply chains.
The business impact can eventually reach revenue, costs, cash flows, asset values, financing and strategy.
For ACCA SBR candidates, this makes nature reporting a valuable current issues topic. It brings together sustainability, risk, materiality, financial reporting and professional judgement.
Candidates working with an ACCA SBR tutor should therefore avoid treating nature as another environmental topic to memorise. The better approach is to understand how a nature-related issue becomes financially relevant.
Climate was never the whole sustainability story
Climate reporting became the natural starting point for sustainability disclosure because greenhouse gas emissions and climate risks were already receiving significant investor and regulatory attention.
The introduction of IFRS S2 gave companies a structured way to report climate-related risks and opportunities.
Nature is more complicated.
Climate reporting can often begin with relatively familiar concepts such as emissions, transition risk and physical risk.
Nature involves a much wider system.
Businesses may depend on freshwater, soil quality, pollination, forests, marine resources, species diversity and functioning ecosystems.
They may also damage those resources through pollution, land use, extraction, waste or changes to habitats.
Those dependencies and impacts can feed back into the company.
A business may rely on a natural resource until that resource becomes scarce.
A company may damage an ecosystem and then face tighter regulation.
A supply chain may depend on agricultural production in an area exposed to declining soil quality.
A project may become more expensive because environmental protections restrict where and how development can take place.
The sustainability issue becomes a financial issue when those effects can reasonably influence the organisation’s prospects.
The ISSB is moving beyond research
Nature-related reporting is no longer sitting only in a research programme.
The ISSB has moved the project into standard-setting and is working towards an exposure draft.
The current proposal is expected to take the form of an IFRS Practice Statement rather than immediately creating a separate mandatory sustainability standard.
That distinction matters.
The Practice Statement is intended to support companies applying IFRS S1 and IFRS S2 when identifying and reporting material nature-related risks and opportunities.
A jurisdiction could later decide to require its use, and the ISSB has left open the possibility of a more formal standard-based outcome in the future.
For candidates, careful wording matters.
Do not say that a new mandatory nature standard already exists.
It does not.
The current development is a proposed Practice Statement designed to guide nature-related reporting alongside the existing ISSB framework.
That is a stronger and more accurate current issues answer.
IFRS S1 already creates the starting point
Another common mistake would be to assume that companies can ignore nature until the new proposals become final.
IFRS S1 already requires companies applying the standard to consider sustainability-related risks and opportunities that could reasonably be expected to affect their prospects.
That means a material nature-related issue may already need attention.
The new project is designed to make application clearer.
This is important because companies may find nature harder to identify and measure than climate.
A business can understand that it purchases timber.
The more difficult questions are whether the supply depends on vulnerable ecosystems, whether those ecosystems face degradation, whether alternative supply exists and whether disruption could become financially material.
The Practice Statement is intended to help bridge that gap.
Dependencies are central to nature reporting
One of the most useful concepts is dependency.
A business depends on nature when its activities rely on ecosystem services or natural resources.
The dependency may be obvious.
A drinks manufacturer needs water.
A farmer depends on soil, weather conditions and pollination.
A fishing business depends on healthy marine ecosystems.
Other dependencies are less visible.
A semiconductor manufacturer may rely on large quantities of high-quality water.
A tourist business may depend on the attractiveness of a natural landscape.
A retailer may depend indirectly on forests, agricultural land or water through suppliers.
This creates an important reporting question.
How vulnerable is the company if the natural resource or ecosystem it relies on deteriorates?
That is where nature reporting becomes commercially useful.
Impacts can create risks even where there is no immediate cost
Companies also affect nature.
That impact does not need to create an accounting liability immediately in order to matter.
A company may extract water faster than local supplies can recover.
It may contribute to habitat loss.
It may create pollution.
Its suppliers may use agricultural practices that damage soil quality.
Those impacts can later become risks.
Regulators may introduce restrictions.
Customers may change buying behaviour.
Investors may demand more information.
Local communities may oppose a development.
The cost of remediation may increase.
A business model that appears profitable today may become more expensive or more difficult to operate.
A strong SBR answer should therefore connect impact with future financial consequences rather than simply describing environmental harm.
Nature-related physical risk can look very different from climate risk
Physical risk is already familiar from climate reporting.
Floods, storms, heat and drought can damage assets and interrupt operations.
Nature-related physical risk can be broader.
A company may face declining water availability even where climate is only one contributing factor.
Agricultural output may fall because soil quality deteriorates.
A crop may become more vulnerable because biodiversity has declined.
An ecosystem that previously protected infrastructure from erosion or flooding may become less effective.
A business may also face cumulative risk.
One individual problem may appear manageable. Several connected nature-related pressures may affect the same site or supply chain at the same time.
This creates a strong professional judgement point.
Nature cannot always be assessed using one isolated metric.
Management needs to understand the wider system supporting the business activity.
Transition risk applies to nature too
Nature-related risk is not limited to physical damage.
Transition risks can arise as governments, markets and businesses respond to nature loss.
Regulation may become stricter.
Planning conditions may change.
Protected areas may expand.
Extraction limits may be introduced.
Product standards may become tougher.
Customers may reject products linked to deforestation or habitat destruction.
Lenders may change their risk appetite.
Investors may require stronger evidence that the company understands its dependencies.
These changes can affect financial performance even when the underlying ecosystem has not yet deteriorated significantly.
That makes transition risk particularly relevant to forward-looking reporting.
Management needs to consider not only what nature-related pressures exist today, but how policy and markets may respond to them.
Opportunities matter as well as risks
Sustainability reporting can become too focused on downside risk.
Nature-related opportunities can also affect prospects.
A business may develop products that use fewer natural resources.
It may redesign supply chains to reduce exposure to vulnerable areas.
A company may restore land in a way that improves resilience and reduces future operating costs.
Better water efficiency may reduce both environmental impact and expenditure.
Improved traceability may strengthen customer trust.
An organisation with strong environmental practices may gain access to customers or finance that competitors struggle to secure.
The important point is that the opportunity must still be commercially relevant.
A vague statement that protecting nature creates opportunities is not useful.
A stronger disclosure explains what the opportunity is, how management plans to respond and what financial effect could follow.
Location matters more for nature than many companies are used to
One of the most interesting parts of the ISSB’s work is the focus on location-specific information.
Nature-related risk is often highly dependent on place.
Two factories producing the same product can face very different risks if one operates in an area of abundant water and the other in a water-stressed region.
Two agricultural suppliers growing the same crop can have very different dependencies depending on soil quality, ecosystem conditions and local biodiversity.
A portfolio-level number may therefore hide the real exposure.
The ISSB has been considering disclosures that help users understand where assets and business activities are vulnerable to nature-related risks or aligned with nature-related opportunities.
For finance teams, this could require information that is not currently collected centrally.
Asset registers may identify cost and location.
Sustainability teams may understand environmental conditions.
Procurement teams may understand supplier exposure.
Risk teams may know where disruptions are occurring.
Nature-related reporting may require those data sets to be connected.
That is a significant implementation challenge.
Aggregation can hide the issue
Financial reports often combine information because excessive detail can overwhelm users.
Nature creates a problem when aggregation removes useful information.
Imagine a company has 50 production sites.
At group level, water costs appear immaterial.
Five of those sites, however, generate a large proportion of group profit and operate in areas facing increasing water stress.
The group average does not tell the real story.
A good disclosure may need to identify the concentration of risk rather than provide only an overall figure.
This creates an important SBR lesson.
Materiality is not simply about the absolute size of an environmental number.
The location, strategic importance and potential financial effect of the exposure also matter.
Climate and nature cannot always be separated
One of the ISSB’s concerns is the connection between climate-related and nature-related risks.
These issues can reinforce one another.
A company may plant large areas of a single species to support a carbon removal strategy. That may help one climate objective while creating biodiversity concerns.
A renewable energy project may reduce emissions while affecting habitats.
A water-intensive transition technology may create pressure in a water-stressed location.
A conservation programme may improve ecosystem resilience and also reduce physical climate risk.
This is why the ISSB is considering guidance around connections, trade-offs and co-benefits.
The reporting should not present climate and nature as two unrelated sustainability programmes when management decisions affect both.
For SBR candidates, this offers a strong analytical angle.
Do not simply identify the positive sustainability effect.
Look for consequences elsewhere.
Nature needs to connect back to financial statements
This is where SBR candidates can turn a general sustainability discussion into a strong reporting answer.
Nature-related risks may affect financial reporting before any dedicated nature disclosure requirement becomes mandatory.
A deterioration in environmental conditions can affect expected cash flows.
Restrictions on land use may affect an asset’s recoverable amount.
Future remediation requirements may affect provisions.
Water scarcity may increase operating costs.
Loss of agricultural productivity may affect inventory costs and margins.
A shorter expected economic life may affect depreciation.
A project may no longer generate the return assumed when an asset was acquired.
Financing assumptions may change if lenders view an activity as increasingly risky.
These connections matter because sustainability reporting should not contradict the accounting.
If management describes nature-related disruption as a major business risk but assumes no effect on forecasts, asset values or provisions, investors may reasonably question the consistency.
Asset impairment is an obvious connection
Impairment is one of the easiest ways to demonstrate the financial relevance of nature.
Consider a factory located in an area where access to water is becoming restricted.
If production depends heavily on water, management may expect lower output or higher costs.
Those changes could reduce future cash flows.
That may create an impairment indicator.
Management should then consider whether the assumptions used in the recoverable amount calculation properly reflect the nature-related risk.
A weak answer would say that water scarcity is bad for the environment.
A stronger answer would explain how it affects production, forecast cash flows and potentially the carrying amount of the asset.
That is the level of connection SBR requires.
Provisions can also become relevant
Nature-related issues may create legal or constructive obligations.
A company may have obligations to restore land following extraction.
Environmental damage may result in remediation requirements.
New regulation may change the cost of compliance.
Management may also have made public commitments that need to be assessed carefully when considering whether a constructive obligation exists.
Candidates should remain technically disciplined.
A public sustainability target does not automatically create a provision.
Recognition depends on whether the relevant accounting criteria are satisfied.
Nature reporting should not lead candidates to abandon established accounting principles.
It should provide new facts to which those principles are applied.
Supply chains will be one of the hardest areas
Many companies may discover that their largest nature-related exposures sit outside their own operations.
A retailer may have limited direct environmental impact at its offices and stores.
Its products may depend on agriculture, forestry, fishing or resource extraction across a large supplier network.
Understanding that exposure can be difficult.
The organisation may not know the precise location of every activity.
Supplier information may be incomplete.
Data quality may vary considerably between countries.
Smaller suppliers may not have sophisticated reporting systems.
The company therefore faces a balance between useful disclosure and practical limitations.
This is why proportionality is important.
Reporting requirements need to produce decision-useful information without assuming that every organisation already has perfect nature data.
Engagement with communities can become financially relevant
The ISSB has also considered how interactions with Indigenous Peoples, Local Communities and other affected stakeholders can relate to nature-related risk and opportunity.
This is not simply a social reporting exercise.
Community relationships can affect whether projects proceed.
Poor engagement may create delays, legal disputes or reputational damage.
Local knowledge may also help a business identify environmental risks earlier.
In some industries, access to land and natural resources depends heavily on maintaining legitimate and durable relationships with affected communities.
The financial relevance comes from the effect on the company’s prospects.
For exam purposes, candidates should avoid turning this into vague stakeholder language.
Explain the commercial connection.
Nature reporting will require better internal controls
Many organisations have spent years improving controls over financial data.
Nature data may not yet have the same maturity.
Information may come from operational systems, suppliers, consultants, geographic data and sustainability teams.
Definitions may vary.
Estimates may be used where measurements are unavailable.
That creates control risk.
A sensible reporting framework should address:
- who owns the data
- how information is collected
- whether definitions are consistent
- which estimates are used
- how management verifies supplier information
- how material nature-related risks are escalated
- whether financial forecasts use the same assumptions as sustainability reporting
The point is not to create another enormous compliance process.
It is to make sure the information reaching investors is supportable.
Boards need to ask where the business depends on nature
The board does not need to become a team of ecologists.
It does need to understand which natural systems the business relies on.
A useful starting point is to ask where the organisation could not operate normally if environmental conditions changed.
Where does the business rely heavily on water?
Which materials have limited substitutes?
Which sites operate close to sensitive ecosystems?
Which suppliers are geographically concentrated?
Where could regulation materially increase costs?
Which sustainability commitments depend on nature-related assumptions?
These questions translate nature into business language.
Once management understands the dependency, it can assess risk.
Current reporting should not become green storytelling
There is a danger that nature reporting becomes another place for attractive photographs and broad commitments.
That would miss the investor purpose.
A statement that a company “values biodiversity” tells users very little.
Investors need to understand material exposure.
What does the company depend on?
Where is the risk?
How could it affect the business?
What is management doing?
What metrics are used?
What financial consequences could arise?
What uncertainty remains?
Those questions produce decision-useful reporting.
The best disclosures may sometimes be less positive than marketing teams would prefer.
That is not a weakness.
Credible reporting includes uncertainty and difficult information.
How this could appear in an SBR question
Imagine a food manufacturing group.
Its main product depends on crops sourced from three countries.
One region has experienced declining water availability and soil degradation.
Management believes supply will remain available but expects procurement costs to rise.
The company has announced a target to source entirely from “nature positive” suppliers within five years.
The impairment model for one production facility assumes stable raw material prices.
The annual report describes nature-related risk as low.
An SBR requirement could ask candidates to advise the board.
A weak answer would discuss biodiversity generally.
A stronger answer would connect the facts.
The business depends on agricultural ecosystems.
The deterioration creates a nature-related physical risk.
Higher input prices may reduce margins and forecast cash flows.
The impairment model may therefore be inconsistent with the known risk.
The low-risk narrative may also contradict operational evidence.
Management should review its sourcing assumptions, financial forecasts and disclosures.
That is professional reporting advice.
How candidates should structure a nature-related answer
Do not memorise a long sustainability essay.
Start with the business dependency or impact.
Identify the risk or opportunity.
Explain how it could affect cash flows, access to finance, asset values or business strategy.
Connect the issue to the financial statements where relevant.
Assess whether management’s existing disclosure is consistent with the evidence.
Finish with a practical recommendation.
This keeps the answer commercial.
It also stops sustainability becoming detached from the rest of SBR.
The October exposure draft will be worth watching
The ISSB is targeting October 2026 for publication of the exposure draft.
That will provide more detail on the proposed Practice Statement and give stakeholders an opportunity to comment.
Candidates should pay attention to the final proposals but avoid turning current issues revision into constant news monitoring.
You do not need to memorise every meeting decision.
Understand the direction.
Nature-related disclosure is moving closer to the ISSB reporting framework.
The focus is on investor-relevant risks and opportunities.
Dependencies and impacts matter because they can affect the organisation’s prospects.
Location can be critical.
Climate and nature can interact.
Financial reporting needs to remain connected.
Those are the points most likely to remain useful even as the proposals develop.
Nature could become a major SBR current issue
Climate will remain important.
Nature adds another layer.
That gives examiners a broad range of potential scenarios involving agriculture, property, mining, manufacturing, consumer goods, supply chains and financial services.
Candidates following an ACCA SBR course should practise nature-related issues through short commercial scenarios rather than building another isolated set of sustainability notes.
Take a dependency.
Add a risk.
Follow the risk into cash flows.
Then ask what changes in the reporting.
That process is far easier to remember than a page of definitions.
What finance teams should do now
Companies do not need to wait for every nature reporting proposal to become final before understanding their exposure.
The first step is mapping.
Where does the business rely on natural resources and ecosystem services?
Where could environmental degradation disrupt operations or suppliers?
Which locations are most vulnerable?
What information does the company already collect?
Where are the largest data gaps?
How do those risks appear in financial planning?
This work has value even before formal reporting requirements develop.
A company cannot manage a material risk it has never identified.
The shift beyond climate is really a shift towards connected reporting
Nature reporting may initially look like another expansion of sustainability disclosure.
The more important change is the move towards connected information.
Nature affects operations.
Operations affect cash flows.
Cash flows affect asset values.
Environmental impacts can affect regulation, reputation and access to resources.
Management responses can create costs and opportunities.
Those effects eventually reach financial reporting and investor decisions.
That is why nature belongs in the reporting conversation.
For SBR candidates, the lesson is straightforward.
Do not learn nature as a separate environmental topic.
Learn to follow the chain.
Dependency.
Risk.
Financial consequence.
Accounting impact.
Disclosure.
Once you can make those connections, nature-related reporting becomes much easier to analyse.
And that is likely to become increasingly valuable as sustainability reporting moves beyond climate.
