Use this guide to connect climate and sustainability foundations with the decisions risk professionals make. Each concept explains a rule or distinction, applies it in an original example and identifies a specific mistake. Work through the foundations first, then use the finance, assessment and reporting sections to interpret business cases alongside the official SCR® curriculum.
Climate science foundations
1. Weather observations and climate distributions
Weather describes conditions at a particular time and place. Climate describes the distribution of those conditions over longer periods, including averages, variability and extremes. A climate trend therefore requires a suitable series of observations, rather than one unusual day.
Worked example: A city has one exceptionally cold winter within a sustained warming trend. That winter demonstrates variability; it does not, by itself, overturn the longer trend.
Mistake to avoid: Using a single local weather event to establish or dismiss global climate change.

2. The greenhouse effect and energy balance
Earth absorbs incoming solar energy and emits infrared radiation. Greenhouse gases absorb and emit some outgoing infrared radiation, changing the energy balance. Increasing their concentrations initially reduces energy loss to space at a given temperature; warming moves the system toward a new balance.
Worked example: Two otherwise identical climate simulations differ only in carbon dioxide concentration. The higher-concentration simulation needs a warmer surface to restore energy balance.
Mistake to avoid: Explaining greenhouse warming as gases simply blocking incoming sunlight.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
3. Forcing and feedback
A forcing changes the climate system’s energy balance; a feedback responds to climate change and amplifies or dampens it. The distinction concerns causal role. Feedbacks help explain why the temperature response can differ from the direct effect of an initial disturbance.
Worked example: Additional carbon dioxide initiates warming. Reduced snow cover then exposes darker surfaces that absorb more sunlight, amplifying the initial warming through an albedo feedback.
Mistake to avoid: Treating an amplifying feedback as an independent initial cause in the same causal chain.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
4. Carbon stocks and emission flows
Emissions are a flow into the atmosphere; atmospheric carbon is a stock affected by emissions and removals. Lower annual emissions can slow stock accumulation without reversing it. Cumulative carbon dioxide emissions are therefore central to understanding warming and the need for sustained reductions.
Worked example: In a simplified annual balance, emissions fall from 12 units to 9 while removals remain 5. The atmospheric stock still increases by 4 units.
Mistake to avoid: Assuming a decline in annual emissions means atmospheric carbon dioxide immediately declines.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
5. Ocean heat and sea-level change
Oceans store substantial heat, creating delayed responses in the climate system. Sea level rises through processes including seawater expansion and the addition of water from land ice. Local relative sea level also depends on land movement, so global averages alone cannot determine a site’s exposure.
Worked example: Two ports face the same global sea-level trend, but one sits on subsiding land. Its relative sea-level increase is greater.
Mistake to avoid: Applying a global sea-level average directly to every coastal asset.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
6. Changing distributions and extreme events
Climate change can alter the mean, spread or shape of a weather distribution. A modest change in average conditions can produce a large change in the frequency of threshold exceedances. Extreme-event risk therefore requires attention to distribution tails, not only average temperature or rainfall.
Worked example: A warehouse’s cooling system fails above a temperature threshold. More days crossing that threshold increase disruption risk even if the average temperature rises only slightly.
Mistake to avoid: Scaling extreme-event losses directly from the change in average conditions.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
7. Event attribution and causal interpretation
Event attribution compares an event’s probability or intensity in a climate influenced by human activity with a counterfactual climate. It evaluates how climate change affected the event, while recognizing that weather variability and local conditions also matter. Attribution is different from estimating the resulting economic damage.
Worked example: An analysis finds a heat event more likely in the altered climate. Assessing business losses still requires information about workers, buildings and protective measures.
Mistake to avoid: Interpreting increased event likelihood as proof that every associated loss was caused solely by climate change.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Sustainability foundations
8. Sustainability across environmental and social systems
Sustainability considers whether activities can continue without undermining environmental systems and human well-being over time. Climate performance is one component. A decision can reduce emissions while creating other environmental or social problems, so assessment must examine relevant trade-offs rather than rely on a single indicator.
Worked example: A lower-carbon material reduces production emissions but creates serious water pressures in a dry region. Its sustainability assessment must address both effects.
Mistake to avoid: Equating a low-carbon product automatically with a sustainable product.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
9. Externalities and private incentives
An externality occurs when an activity affects others without that effect being fully reflected in the decision-maker’s costs or benefits. Negative environmental externalities can make privately attractive activities socially costly. Policies or contracts may change incentives by bringing some external costs into the decision.
Worked example: A factory saves 30 monetary units by using a dirtier process but causes 70 units of downstream damage. Its private saving accompanies a net social cost of 40.
Mistake to avoid: Treating a company’s accounting profit as a complete measure of societal value.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
10. Financial materiality and impact materiality
Financial materiality concerns sustainability matters that affect an organization’s financial prospects. Impact materiality concerns the organization’s effects on people and the environment. These perspectives can overlap, but they ask different questions. The applicable reporting framework determines how each perspective must be assessed.
Worked example: A company’s water extraction damages a wetland. That is an impact; a subsequent restriction on extraction also creates a potential financial consequence.
Mistake to avoid: Assuming an environmental impact matters only after it produces an immediate financial loss.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
11. Life-cycle boundaries and functional comparison
Life-cycle assessment considers impacts across relevant stages, from inputs through use and disposal. Comparisons need a consistent functional unit: the service delivered, not merely the number or weight of products. Otherwise, different lifetimes or usage patterns can distort conclusions.
Worked example: A reusable container has higher manufacturing emissions but serves many deliveries. Compare emissions per completed delivery over its usable life, including cleaning and disposal.
Mistake to avoid: Comparing one reusable item with one disposable item without accounting for the service each provides.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
12. Circularity and rebound effects
Circular approaches preserve product and material value through durability, repair, reuse and recycling. Their benefits depend on energy requirements, material quality and whether they displace new production. Efficiency savings can also encourage additional consumption, partly offsetting the intended reduction in resource use.
Worked example: Repair extends a machine’s life and avoids a replacement. Buying extra machines because repairs became cheaper could reduce that resource-saving benefit.
Mistake to avoid: Assuming every increase in recycling or efficiency guarantees a proportional fall in total environmental impact.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Climate risk and business exposure
13. Acute and chronic physical risk
Acute physical risks arise from events such as floods or storms. Chronic physical risks arise from persistent changes such as rising temperatures or water scarcity. They can interact: a chronic change may intensify an acute event or reduce an organization’s ability to withstand it.
Worked example: A farm faces gradual drying that weakens yields, then suffers an unusually severe drought. The assessment includes both the persistent trend and the event.
Mistake to avoid: Classifying physical risk only by disasters and overlooking slower changes in operating conditions.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
14. Transition risk drivers
Transition risk arises from changes associated with moving toward a lower-emission economy. Drivers include policy, technology, market preferences and reputational pressures. Identifying the driver is only the first step; assessment must trace how it affects demand, costs, asset values or access to finance.
Worked example: A cheaper low-emission substitute reduces demand for an incumbent product even without a new regulation. The immediate driver is technological and market change.
Mistake to avoid: Treating transition risk as synonymous with carbon regulation.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
15. Hazard, exposure and vulnerability
Physical risk depends on a hazard, the assets or activities exposed to it, and their vulnerability. Hazard maps indicate potential conditions, but they do not directly measure losses. Asset characteristics and protective measures determine how a given hazard translates into damage or disruption.
Worked example: Two facilities share a flood zone. Elevated equipment makes one less vulnerable, although both remain exposed to the same hazard.
Mistake to avoid: Ranking asset risk using hazard severity alone while ignoring what is exposed and how it can be damaged.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
16. Transmission into financial risk
Climate risks often reach financial statements through familiar channels: revenue, operating costs, capital expenditure, collateral values and funding conditions. A useful assessment connects the climate driver to these channels before estimating credit, market or liquidity consequences. The same driver may affect several channels simultaneously.
Worked example: Repeated flooding interrupts sales and lowers collateral value. A lender may face both weaker debt repayment and lower recovery if default occurs.
Mistake to avoid: Adding an unexplained climate surcharge without identifying the financial transmission mechanism.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
17. Compound events and cascading disruption
Compound risk involves interacting hazards or conditions; cascading risk describes consequences spreading through connected systems. Dependencies can make total losses exceed what isolated asset assessments suggest. Correlation and sequence matter, especially when transport, power and suppliers share exposure.
Worked example: Flooding closes a factory while a power outage disables its backup supplier. Separate continuity assessments would miss their shared regional dependence.
Mistake to avoid: Adding independent loss estimates when disruptions are linked or when one failure amplifies another.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
18. Asset life and assessment horizon
The assessment horizon should reflect how long an asset, obligation or strategy remains exposed. Near-term financial forecasts may omit risks relevant to long-lived infrastructure. Conversely, a distant scenario should not be presented as an immediate loss without explaining timing and transmission.
Worked example: A port investment has a long operating life. Its assessment considers evolving coastal hazards beyond the company’s next annual budget.
Mistake to avoid: Using a short budgeting horizon to dismiss risks that affect an asset during its expected service life.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
19. Stranded assets and premature impairment
An asset becomes stranded when changes prevent it from delivering its expected economic value before the anticipated end of its life. Policy, technology, demand or physical conditions can contribute. Stranding is an economic outcome, not a label that automatically applies to every emissions-intensive asset.
Worked example: A specialized plant loses its customers after a competing technology becomes cheaper. Its expected cash flows fall below those assumed when it was built.
Mistake to avoid: Inferring stranding solely from an asset’s emissions without examining economics, alternatives and timing.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Policy, governance and risk culture
20. Mitigation and adaptation
Mitigation addresses the causes of climate change by reducing emissions or increasing removals. Adaptation adjusts systems to actual or expected climate effects. The two are complementary, but a measure’s purpose and consequences should be examined separately because adaptation can increase emissions or shift risk elsewhere.
Worked example: Insulation reduces cooling demand and emissions while helping occupants tolerate heat. A diesel-powered cooling expansion may improve heat protection but increase emissions.
Mistake to avoid: Assuming every adaptation measure also mitigates climate change.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
21. Carbon taxes and emissions trading
A carbon tax sets a price on covered emissions, while an emissions trading system sets an allowance framework in which prices emerge through trading. Outcomes depend on coverage and design. For business analysis, distinguish the emissions quantity, applicable price and ability to pass costs to customers.
Worked example: At an illustrative charge of 40 per tonne, 10,000 covered tonnes create a gross charge of 400,000 before any specified adjustments.
Mistake to avoid: Assuming all company emissions face the same carbon price in every jurisdiction.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
22. International commitments and domestic implementation
International climate cooperation establishes shared objectives and mechanisms for national commitments. A company’s direct obligations depend on relevant domestic implementation and other applicable rules. National ambitions, enacted measures and company-level requirements are related but distinct sources of information.
Worked example: A country announces a stronger climate commitment. An analyst separately checks enacted measures before treating a specific operating cost as mandatory.
Mistake to avoid: Turning an international or national aspiration directly into an assumed legal duty for every company.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
23. Policy instruments and distributional effects
Climate policy may use prices, standards, subsidies, public investment or information requirements. Instruments differ in incentives, administrative demands and how costs and benefits are distributed. Assess both the environmental mechanism and the effects on households, workers and businesses.
Worked example: An efficiency subsidy reduces purchase costs, but households unable to fund the remaining amount may receive little benefit. Complementary financing could change participation.
Mistake to avoid: Evaluating a policy only by its announced emissions objective while ignoring implementation and distribution.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
24. Governance and accountable decisions
Effective climate governance connects oversight, management responsibility and decision authority. Responsibilities should identify who approves strategy, who implements controls and who challenges assumptions. A climate committee adds value only if its findings influence ordinary investment and risk decisions.
Worked example: Management proposes a coastal expansion. The investment committee requires a physical-risk assessment, and the risk function independently challenges its assumptions before approval.
Mistake to avoid: Treating the existence of a committee as evidence that climate risk influences decisions.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
25. Risk culture and incentive alignment
Risk culture shapes how people identify, report and respond to uncertainty. Incentives can reinforce or undermine climate objectives, especially when short-term targets conflict with longer-term risk controls. Useful governance encourages escalation and evaluates performance using measures within a person’s influence.
Worked example: A procurement bonus rewards the lowest immediate price only. Adding relevant resilience and supplier-performance measures reduces pressure to ignore known supply risks.
Mistake to avoid: Expecting a climate policy statement to overcome incentives that reward contradictory behavior.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Sustainable finance and investment
26. Green bonds and use of proceeds
A green bond’s defining structure directs proceeds toward specified eligible environmental activities. Assess project eligibility, allocation and reporting separately from the issuer’s overall business. The label does not automatically change repayment obligations or eliminate the issuer’s credit risk.
Worked example: A manufacturer funds energy-efficiency upgrades with a green bond. Investors still assess its ability to repay, alongside whether proceeds reach the stated projects.
Mistake to avoid: Assuming a green label guarantees either superior environmental outcomes or stronger credit quality.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
27. Sustainability-linked financing
Sustainability-linked financing connects contractual terms to specified performance indicators and targets. Its credibility depends on the indicator’s relevance, target ambition, measurement reliability and contractual consequences. Proceeds need not be reserved for particular green projects unless the instrument separately requires that.
Worked example: A loan’s terms change if the borrower misses an emissions target. Assess whether the target captures the borrower’s main emissions sources and can be verified.
Mistake to avoid: Confusing performance-linked financing with financing restricted to eligible environmental expenditures.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
28. Project finance and repayment drivers
Project finance relies substantially on a project’s cash flows for repayment. Climate-related projects still face construction, operating, resource and counterparty risks. Assess how contracts allocate these risks and whether projected revenues remain sufficient under adverse conditions.
Worked example: A renewable-power project has a long-term buyer, but construction delays postpone revenue while financing costs continue. The purchase contract alone does not resolve completion risk.
Mistake to avoid: Treating an environmentally beneficial project as financially viable without testing its repayment drivers.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
29. Taxonomies and classification boundaries
A sustainable finance taxonomy classifies activities against specified criteria. Eligibility, alignment and an organization’s overall sustainability are different judgments. Classification depends on the applicable framework, activity and supporting evidence; similarly named taxonomies may apply different criteria.
Worked example: A diversified company has one activity meeting a taxonomy’s criteria. That supports classification of the qualifying activity, not an automatic claim that every operation is aligned.
Mistake to avoid: Transferring a classification across jurisdictions or applying it to an entire issuer without checking boundaries.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
30. Climate assumptions in investment valuation
Climate factors can change expected cash flows, discount rates or both. Keep the mechanism explicit and avoid counting the same risk twice. Discounting also means an attractive environmental purpose does not substitute for an assessment of financial value.
Worked example: An investment pays 110 in one year. Its present value is 100 at a 10% discount rate and 88 at 25%, before considering any change in the expected payment.
Mistake to avoid: Reducing cash flows and increasing the discount rate for the same uncertainty without justification.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
31. Portfolio changes and real-world effects
A portfolio’s emissions can fall because holdings change, companies reduce emissions or measurement changes. These mechanisms have different implications for real-world decarbonization. Investment impact assessment should identify the causal channel, such as financing new capacity or influencing company decisions.
Worked example: A fund sells a high-emission company to another investor. Its reported portfolio emissions fall, but the company’s operations continue unchanged.
Mistake to avoid: Equating a cleaner portfolio automatically with a reduction in economy-wide emissions.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Risk measurement, data and controls
32. Absolute metrics and intensity metrics
An absolute metric measures total quantity; an intensity metric divides that quantity by an activity measure. Both can be useful, but they answer different questions. Changes in output or revenue can improve intensity even while total emissions increase, so always examine the numerator and denominator.
Worked example: Emissions rise from 1,000 to 1,200 tonnes while output rises from 500 to 800 units. Intensity falls from 2 to 1.5 tonnes per unit.
Mistake to avoid: Describing an intensity improvement as an absolute emissions reduction.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
33. Expected annual loss and tail loss
Expected annual loss combines possible losses with their annual probabilities. It is an average across possible outcomes, not the amount expected in every year. Tail losses describe severe outcomes and remain important even when their contribution to the average is modest.
Worked example: Two mutually exclusive annual events have probabilities of 2% and 0.5%, with losses of 1 million and 4 million. Expected annual loss is 40,000.
Mistake to avoid: Using an average loss estimate as the maximum loss a business needs to withstand.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
34. Climate drivers in credit loss
A simplified expected credit loss calculation multiplies exposure at default, probability of default and loss given default. Climate drivers can affect each input through different mechanisms. This calculation illustrates transmission; actual accounting and regulatory methods may require additional detail.
Worked example: For exposure of 10 million, default probability of 2% and loss given default of 40%, expected loss is 80,000. At 3% and 50%, it becomes 150,000.
Mistake to avoid: Adjusting default probability while ignoring climate damage to collateral and potential recovery.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
35. Operational resilience and critical dependencies
Operational resilience examines whether important services can continue or recover when disruption occurs. Climate assessment should identify critical processes, dependency bottlenecks and credible substitutes. Geographic separation alone may not provide resilience when alternatives share infrastructure or upstream suppliers.
Worked example: A business has two warehouses, but both depend on the same bridge. Bridge closure can interrupt both distribution routes, revealing a common dependency.
Mistake to avoid: Counting backup facilities without checking whether they can function independently under the same event.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
36. Risk appetite and actionable limits
Risk appetite expresses the risk an organization is willing to accept. Limits translate that position into decisions, monitoring and escalation. Climate-related limits should use interpretable measures and clearly defined boundaries, while recognizing that uncertain data may require judgment rather than false precision.
Worked example: A lender monitors concentrations in drought-sensitive borrowers and escalates proposed increases for review. The limit connects a known exposure to an approval process.
Mistake to avoid: Setting a climate target without specifying what happens when exposure approaches or exceeds it.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
37. Data provenance, proxies and validation
Data quality depends on origin, boundary, timeliness and fitness for purpose. Reported data, estimates, sector proxies and remote observations provide different evidence. Preserve provenance and uncertainty, then validate important inputs against independent information where feasible.
Worked example: A supplier has no measured emissions data. An analyst uses a sector proxy, flags it as estimated and tests whether the decision changes under a plausible range.
Mistake to avoid: Presenting a modeled or satellite-derived estimate as a directly measured value without qualification.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
38. Insurance and residual risk
Insurance transfers specified financial losses subject to coverage terms, deductibles, exclusions and limits. It does not remove the underlying hazard or ensure operational continuity. Risk management should identify uninsured consequences and consider whether coverage remains available on acceptable terms.
Worked example: A flood policy covers equipment damage but excludes some business interruption. The company still faces lost customer orders while repairs occur.
Mistake to avoid: Treating an insured asset as having no remaining physical or financial climate risk.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Models, scenarios and uncertainty
39. Scenarios as conditional futures
A scenario describes a plausible future under specified assumptions. It is a tool for exploring consequences, rather than necessarily a prediction or a probability-weighted forecast. Results should always be interpreted together with the assumptions about policy, technology, emissions and economic conditions.
Worked example: A rapid-policy scenario produces higher near-term compliance costs. That result means costs rise under those assumptions; it does not establish that the policy path will occur.
Mistake to avoid: Reporting a scenario outcome as the organization’s most likely future without a forecasting basis.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
40. The model chain from climate to finance
Climate financial analysis often links emissions pathways, climate projections, hazards, asset impacts and financial outcomes. Each link introduces assumptions and uncertainty. A credible result requires checking the chain, because detail in the final financial number cannot repair weak inputs earlier in the process.
Worked example: A flood-loss model uses detailed building values but unreliable asset coordinates. Its precise monetary output remains unreliable because exposure was incorrectly located.
Mistake to avoid: Judging model credibility by the number of decimal places in the final result.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
41. Scenario diversity and internal consistency
A useful scenario set explores meaningfully different risk conditions rather than minor variations of one future. Assumptions within each scenario must remain consistent: policy timing, technology adoption and physical outcomes should form a coherent narrative. Different scenarios can expose different weaknesses in the same strategy.
Worked example: A delayed-transition scenario combines limited early action with abrupt later adjustment. Pairing it with smooth early investment would undermine the intended narrative.
Mistake to avoid: Selecting several scenarios that all leave the organization’s main vulnerability untested.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
42. Downscaling and local interpretation
Downscaling translates broader climate information into finer spatial detail using statistical or dynamical methods. Finer resolution can improve relevance but does not automatically guarantee accuracy. Local topography, infrastructure and drainage may require additional analysis beyond the climate model.
Worked example: A regional rainfall projection informs a city assessment, but street-level flood estimates also require terrain and drainage information. Rainfall change alone cannot locate every flooded building.
Mistake to avoid: Assuming a high-resolution map resolves all local exposure and vulnerability uncertainty.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
43. Sensitivity analysis and stress testing
Sensitivity analysis changes selected inputs to reveal what drives an outcome. Stress testing evaluates performance under specified adverse conditions, often combining several changes. Both support decisions, but neither automatically assigns probabilities to the tested outcomes.
Worked example: An analyst first varies carbon prices while holding demand constant, then tests a stress combining higher prices, lower sales and tighter funding. The exercises answer different questions.
Mistake to avoid: Calling a single-variable sensitivity a comprehensive climate stress test.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
44. Uncertainty and robust decisions
Climate assessments contain uncertainty about future choices, natural variability, models and data. A robust decision performs acceptably across several plausible conditions rather than depending on one precise forecast. Validation should examine assumptions, historical performance where relevant and the limits of extrapolation.
Worked example: A facility chooses an upgrade that reduces losses across several heat scenarios instead of an option that works only under the mildest projection.
Mistake to avoid: Assuming a model calibrated to past conditions must remain reliable under substantially different future conditions.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Net zero and emissions pathways
45. Net zero, reductions and residual emissions
Net zero balances specified emissions with qualifying removals within a defined boundary and period. Gross reductions lower emissions at source; removals address residual emissions. A credible assessment distinguishes these components and examines the applicable framework rather than treating any claimed compensation as equivalent.
Worked example: An organization emits 100 units and achieves 20 units of qualifying removals. Its net balance is 80, so it has not reached net zero within that boundary.
Mistake to avoid: Calling a partial reduction or an unspecified offset purchase net zero.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
46. Pathways and cumulative emissions
Two pathways can reach the same endpoint while producing different cumulative emissions. Earlier reductions generally lower cumulative carbon dioxide emissions compared with delayed reductions to the same endpoint. Assess the trajectory and interim actions, not only the final target date.
Worked example: Over three illustrative years, emissions of 90, 60 and 30 total 180. A delayed pathway of 100, 100 and 30 totals 230 despite the same final-year emissions.
Mistake to avoid: Treating identical endpoint targets as identical contributions to limiting warming.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
47. Target boundaries and credible comparisons
An emissions target needs a base period, organizational and emissions boundary, measurement basis and timeframe. Absolute and intensity targets can imply different outcomes. Changes in company structure or calculation methods must be handled transparently so that progress reflects comparable quantities.
Worked example: A company claims a reduction after selling a factory. Compare results on a consistent boundary before concluding that its continuing operations became less emissions-intensive.
Mistake to avoid: Comparing targets or progress percentages without checking which emissions and activities they include.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
48. Removal durability and reversal risk
A carbon removal’s climate value depends partly on storage durability and the risk that stored carbon returns to the atmosphere. Biological and geological storage can have different risk characteristics. Measurement, monitoring and responses to reversal are therefore relevant alongside the quantity initially removed.
Worked example: A restoration project stores carbon in vegetation, but a later fire releases some of it. The original storage estimate must be considered together with that reversal.
Mistake to avoid: Treating all tonnes of claimed removal as interchangeable regardless of storage duration and risk.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
49. Carbon-credit integrity
Credit integrity requires examining whether the credited outcome is additional, measured against a credible baseline and protected against leakage and double counting. Avoided emissions and removals represent different outcomes. The credit’s permitted use also depends on the relevant claim framework.
Worked example: A project claims credit for a change already required and expected without credit revenue. Its additionality is doubtful even if the physical emissions calculation is correct.
Mistake to avoid: Accepting a credit’s stated quantity without checking whether it represents a credible additional outcome.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Nature dependencies and risk assessment
50. Dependencies and impacts on nature
A dependency is a business reliance on nature, such as pollination or water purification. An impact is a change the business causes to nature. Assess both directions because damaging an ecosystem can weaken services on which the business or its supply chain depends.
Worked example: An orchard depends on pollinators while its land management affects their habitat. Dependency assessment alone would overlook its contribution to the risk.
Mistake to avoid: Using a list of environmental impacts as a substitute for identifying business dependencies.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
51. Biodiversity and ecosystem function
Biodiversity includes variation within species, between species and among ecosystems. Ecosystem functions and resilience cannot be represented fully by one species count or a carbon measure. Nature assessment should select indicators relevant to the ecological condition and business dependency being examined.
Worked example: A plantation stores carbon but supports less varied habitat than the ecosystem it replaced. Carbon storage alone cannot establish an improvement in biodiversity.
Mistake to avoid: Treating carbon gains as proof of equivalent gains in ecosystem health.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
52. Location-specific nature exposure
Nature dependencies and impacts are strongly location-specific. Water pressure, habitat condition and ecosystem sensitivity differ between places, even for identical activities. Useful assessment combines activity information with site or sourcing locations and the conditions of the surrounding ecosystem.
Worked example: Two plants use equal volumes of water. The plant in a heavily stressed catchment may face greater ecological and operational consequences.
Mistake to avoid: Ranking water-related nature risk solely by total consumption without examining local availability and competing demands.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
53. Nature-related physical and transition risk
Nature-related physical risk arises when ecosystem degradation disrupts services businesses rely on. Nature-related transition risk arises from responses such as policy changes, market shifts or stakeholder expectations. These can interact with climate risks, but they have distinct drivers that require examination.
Worked example: Declining water quality raises treatment costs, while a new sourcing requirement changes supplier eligibility. The first is a physical dependency problem; the second is a transition response.
Mistake to avoid: Treating every nature-related risk as another name for climate risk.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
54. The mitigation hierarchy for nature impacts
The mitigation hierarchy prioritizes avoiding impacts, then minimizing them and restoring affected systems before considering compensation for residual impacts. The sequence matters because some losses are difficult or impossible to replace. Compensation requires careful assessment of ecological equivalence and uncertainty.
Worked example: A developer first considers moving a project away from sensitive habitat before proposing restoration elsewhere. Avoidance directly prevents the identified impact.
Mistake to avoid: Beginning with compensation while leaving feasible avoidance options unexplored.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
Transition plans and carbon reporting
55. Scope 1, Scope 2 and Scope 3 emissions
Scope 1 covers direct emissions from sources owned or controlled by the organization. Scope 2 covers emissions associated with purchased energy. Scope 3 covers other indirect value-chain emissions. Classification follows the reporting boundary and activity, rather than whether the emissions feel close to the business.
Worked example: For an office, fuel burned in its controlled boiler is Scope 1, purchased electricity is Scope 2, and employee commuting is generally Scope 3.
Mistake to avoid: Classifying purchased electricity as direct emissions simply because it is consumed onsite.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
56. Organizational boundaries and consolidation
An emissions inventory needs a consistent method for deciding which operations belong within the reporting organization. Equity-share and control approaches can produce different boundaries. Specify the chosen approach and apply it consistently before comparing inventories or evaluating progress.
Worked example: A company owns part of a joint venture but does not control it. Its inclusion can differ under equity-share and control approaches, so ownership percentage alone does not settle the inventory.
Mistake to avoid: Combining operations selected under incompatible consolidation approaches without explanation.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
57. Activity data and emissions factors
A basic emissions estimate multiplies activity data by a compatible emissions factor. Check units, period, location and the factor’s boundary. When combining greenhouse gases, carbon dioxide equivalent depends on the chosen global warming potential basis, which should be stated consistently.
Worked example: Using an illustrative factor of 0.3 tonnes of carbon dioxide equivalent per megawatt-hour, 200 megawatt-hours produces an estimate of 60 tonnes.
Mistake to avoid: Multiplying kilowatt-hours by a factor expressed per megawatt-hour without converting units.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
58. Transition plans and implementation evidence
A transition plan connects objectives to actions, resources, responsibilities and dependencies. Assess whether capital expenditure, procurement and operating decisions support the proposed pathway. Identify reliance on external developments, such as infrastructure or technology availability, rather than presenting those developments as assured.
Worked example: A fleet target depends on vehicle replacement and charging capacity. A useful plan assigns budgets and responsibilities for both, and identifies grid-connection uncertainty.
Mistake to avoid: Treating a distant target as an implementation plan without funded actions or accountable owners.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
59. Financed emissions and attribution
Financed emissions attribute a share of an entity’s or asset’s emissions to financing relationships under a specified method. They are distinct from a financial institution’s operational emissions. Attribution depends on asset class, valuation basis and data quality, so simplified calculations must state their assumptions.
Worked example: Under a simplified attribution rule, financing of 5 million against a denominator of 25 million assigns 20% of 10,000 tonnes, or 2,000 tonnes.
Mistake to avoid: Presenting a simplified attribution rule as universally applicable to every financial asset.
Source reference: SCR® Exam, Sustainability & Climate Risk Certificate | GARP
60. Reporting consistency and evidential support
Useful carbon reporting makes boundaries, methods, estimates and significant changes understandable. Reconcile reported progress with acquisitions, disposals and methodology changes. Assurance can strengthen confidence within its stated scope, but readers must still examine what was assessed and which limitations remain.
Worked example: An inventory falls after a disposal and a factor update. Reporting separates those effects from operational reductions so readers can interpret the change.
Mistake to avoid: Assuming an assurance statement verifies every sustainability claim or establishes that a transition target will be achieved.
