Question 1ITIL 4 Sustainability in Digital and IT

In ITIL 4, sustainability management practices are primarily concerned with which outcome?

  1. Balancing environmental, social, and economic impacts of products and services across their lifecycle Correct answer.
  2. Reducing the number of incidents reported to the service desk
  3. Ensuring that service level agreements are met
  4. Maximizing short-term financial return for shareholders

Explanation

ITIL 4 sustainability management addresses the triple bottom line: environmental, social, and economic effects of services across the whole lifecycle. It is not limited to financial performance or operational metrics such as SLA compliance or incident volumes.

Question 2ITIL 4 Sustainability in Digital and IT

Which concept from ITIL 4 describes the interconnected parts of an organization that must be aligned to create value, and is also used to structure sustainability initiatives?

  1. The four dimensions of service management Correct answer.
  2. The continual improvement model
  3. The RACI matrix
  4. The service value chain

Explanation

The four dimensions cover organizations and people, information and technology, partners and suppliers, and value streams and processes. Sustainability work must be coordinated across all four dimensions, otherwise gains in one area are undermined by another.

Question 3ITIL 4 Sustainability in Digital and IT

A service provider wants to reduce the energy consumed by its data centres. Which sustainability management activity should come first?

  1. Replacing all hardware with new equipment
  2. Immediately purchasing carbon offsets for all operations
  3. Publishing an annual sustainability report to customers
  4. Establishing a baseline measurement of current energy consumption and related emissions Correct answer.

Explanation

Measurement establishes the baseline against which improvement can be planned and verified; without it, targets and progress claims cannot be substantiated. Offsets, reporting, and hardware replacement are later decisions that depend on reliable data.

Question 4ITIL 4 Sustainability in Digital and IT

What does the term 'greenwashing' mean in the context of IT services?

  1. Making misleading or unsubstantiated claims about the environmental benefits of a service Correct answer.
  2. Retiring legacy hardware responsibly
  3. Applying circular economy principles to packaging
  4. Using renewable energy in a data centre

Explanation

Greenwashing is the practice of overstating or fabricating environmental credentials so that stakeholders form an inaccurate impression. It is a communication and governance risk, addressed by verifiable evidence and transparent reporting.

Question 5ITIL 4 Sustainability in Digital and IT

Which of the following best describes the circular economy principle as applied to IT asset management?

  1. Extending the warranty period on all new purchases
  2. Outsourcing disposal to the lowest-cost vendor
  3. Maximizing the number of devices purchased per employee
  4. Keeping materials in use through reuse, repair, remanufacture, and recycling rather than disposal Correct answer.

Explanation

The circular economy aims to retain the value of materials and products for as long as possible by looping them back into use. In IT asset management this means designing for longevity, repairing, refurbishing, and recovering components before final recycling.

Question 6ITIL 4 Sustainability in Digital and IT

An organization is defining sustainability objectives. Which characteristic makes an objective suitable for the 'manage, improve, and measure' aspect of sustainability management?

  1. It is specific, measurable, and time-bound with an assigned owner Correct answer.
  2. It is expressed only in qualitative terms
  3. It is set by the supplier rather than the organization
  4. It is aspirational and open-ended

Explanation

Objectives must be measurable and owned so that progress can be tracked and corrective action taken. Vague or externally imposed objectives cannot be managed or verified through the value chain.

Question 7ITIL 4 Sustainability in Digital and IT

In ITIL 4, which practice is most directly responsible for ensuring that sustainability requirements are captured in the design of new services?

  1. Service desk
  2. Design and transition practices that embed requirements into service design Correct answer.
  3. Incident management
  4. Problem management

Explanation

Sustainability requirements must be built in during design and transition, where architecture, sourcing, and technology choices are decided. Operational practices such as incident, service desk, and problem management act after the service exists.

Question 8ITIL 4 Sustainability in Digital and IT

What is the primary purpose of the 'relationship management' practice in supporting sustainability?

  1. Measuring carbon emissions from cloud services
  2. Aligning stakeholder expectations and needs so that sustainability commitments are understood and maintained Correct answer.
  3. Writing the sustainability report
  4. Purchasing energy-efficient hardware

Explanation

Relationship management builds and maintains the links between the organization and its stakeholders, including on sustainability expectations. It ensures commitments are communicated, agreed, and sustained rather than being purely technical tasks.

Question 9ITIL 4 Sustainability in Digital and IT

Which statement about the scope of sustainability in ITIL 4 is correct?

  1. It is limited to the organization's own employees
  2. It applies only to the facilities management function
  3. It applies only to on-premises data centres
  4. It covers the whole service value system, including partners and suppliers in the value chain Correct answer.

Explanation

Sustainability spans the entire service value system and value chain, including partners and suppliers whose activities contribute to the organization's impacts. Restricting scope to facilities, employees, or on-premises infrastructure would miss significant environmental and social effects.

Question 10ITIL 4 Sustainability in Digital and IT

A service team wants to reduce the environmental impact of software it develops. Which approach best reflects sustainability management guidance?

  1. Adding more servers to improve performance
  2. Optimizing code and architecture to reduce compute and storage demand Correct answer.
  3. Deploying additional monitoring agents on every host
  4. Increasing the frequency of full backups

Explanation

Efficient code and architecture reduce the compute, storage, and network resources required, lowering energy use and emissions. Adding capacity, backups, or agents increases resource consumption and works against sustainability goals.

Question 11ITIL 4 Sustainability in Digital and IT

Which ITIL 4 practice provides the mechanism for recording and managing sustainability-related improvements alongside other improvements?

  1. Continual improvement Correct answer.
  2. Capacity and performance management
  3. Service configuration management
  4. Change enablement

Explanation

Continual improvement is the practice through which improvement opportunities, including sustainability initiatives, are identified, prioritized, and realized. Other practices support specific changes but do not own the improvement lifecycle.

Question 12ITIL 4 Sustainability in Digital and IT

Why is supplier and partner engagement important for an organization's sustainability performance?

  1. Supplier contracts remove the need for internal measurement
  2. Partners are legally responsible for the organization's own emissions
  3. Suppliers always have lower emissions than the organization
  4. A significant share of environmental and social impacts occurs in the supply chain and must be influenced through contracts and collaboration Correct answer.

Explanation

Much of the environmental and social footprint of digital services arises upstream and downstream in the value chain. Organizations must therefore set expectations, include sustainability clauses, and collaborate with partners to manage those impacts.

Question 13ITIL 4 Sustainability in Digital and IT

Which set of indicators best represents the three pillars of sustainability for an IT service?

  1. Energy consumption and emissions, employee wellbeing and digital inclusion, and cost efficiency and long-term viability Correct answer.
  2. Number of servers, number of users, and number of applications
  3. Uptime, ticket volume, and mean time to repair
  4. Revenue, market share, and brand awareness

Explanation

The three pillars are environmental, social, and economic. The first option maps directly to each pillar, whereas the others describe operational, commercial, or inventory metrics that do not cover all three dimensions.

Question 14ITIL 4 Sustainability in Digital and IT

What role does the 'measurement and reporting' practice play in sustainability management?

  1. It guarantees that emissions targets will be achieved
  2. It provides reliable data and reporting so that sustainability performance can be assessed and communicated Correct answer.
  3. It replaces the need for stakeholder engagement
  4. It sets the price of carbon offsets

Explanation

Measurement and reporting supplies the evidence base for decision-making and transparent communication of sustainability performance. It does not by itself deliver targets, replace engagement, or determine market prices.

Question 15ITIL 4 Sustainability in Digital and IT

An organization is choosing between extending the life of existing laptops and buying new low-energy models. Which consideration is most consistent with sustainability management?

  1. Choosing based on purchase price alone
  2. Always keeping old equipment because manufacturing is irrelevant
  3. Comparing the full lifecycle impact of both options, including manufacturing, use, and end-of-life Correct answer.
  4. Always choosing the newest model because it uses less power in use

Explanation

Embodied impacts from manufacturing and disposal can outweigh in-use efficiency gains, so decisions should be based on full lifecycle assessment. Focusing only on use-phase power, manufacturing, or price gives an incomplete picture.

Question 16ITIL 4 Sustainability in Digital and IT

Which statement best explains the relationship between digital technology and sustainability in ITIL 4 guidance?

  1. Digital technology can both enable sustainability improvements and create negative impacts that must be managed Correct answer.
  2. Digital technology only creates negative impacts
  3. Digital technology removes the need for sustainability governance
  4. Digital technology is always neutral in its sustainability effects

Explanation

Digital services can enable efficiency, dematerialization, and better decision-making while also consuming energy and resources and creating e-waste. Sustainability management must therefore exploit the benefits and control the negative effects.

Question 17ITIL 4 Sustainability in Digital and IT

A sustainability objective has been set to cut data centre emissions by 30 percent in two years. Which action best supports tracking progress against this objective?

  1. Delegating all tracking to the facilities team without reporting
  2. Relying on supplier marketing claims about efficiency
  3. Waiting until the end of the two years to measure results
  4. Defining a regular measurement cadence with agreed metrics and reporting to an accountable owner Correct answer.

Explanation

Progress toward a target requires regular measurement using agreed metrics and clear accountability. Delaying measurement, isolating tracking, or relying on unverified claims prevents timely corrective action.

Question 18ITIL 4 Sustainability in Digital and IT

Which of the following is an example of a social sustainability consideration for a digital service?

  1. Ensuring accessibility of the user interface for people with disabilities Correct answer.
  2. Increasing the frequency of software releases
  3. Reducing the number of servers in the data centre
  4. Selecting a lower-cost cloud region

Explanation

Social sustainability concerns people and equity, including accessibility, inclusion, and wellbeing. Server counts, cloud region cost, and release frequency are environmental, economic, or operational matters.

Question 19ITIL 4 Sustainability in Digital and IT

How should sustainability risks be treated within the ITIL 4 risk management approach?

  1. They should be ignored because they are non-financial
  2. They should be identified, assessed, and managed alongside other risks in the service value system Correct answer.
  3. They should be delegated entirely to external auditors
  4. They should be managed only after a regulatory penalty occurs

Explanation

Sustainability risks such as regulatory, reputational, and environmental risks are business risks and should be integrated into the organization's risk management. Ignoring them, reacting only after penalties, or outsourcing accountability is inconsistent with good governance.

Question 20ITIL 4 Sustainability in Digital and IT

What is the significance of the 'value streams and processes' dimension for sustainability improvement?

  1. It shows how work flows through the organization and where waste, emissions, and inefficiency can be removed Correct answer.
  2. It defines the organizational hierarchy and reporting lines
  3. It lists the suppliers approved for procurement
  4. It specifies the technology architecture standards

Explanation

Analyzing value streams reveals where activities add value and where waste or unnecessary resource consumption occurs. This makes it a key dimension for identifying sustainability improvements in processes.

Question 21ITIL 4 Sustainability in Digital and IT

Which approach best reflects the ITIL 4 principle of 'collaborate and promote visibility' in a sustainability programme?

  1. Sharing sustainability data and decisions openly with stakeholders across the value chain Correct answer.
  2. Keeping all sustainability data confidential within the executive team
  3. Restricting sustainability discussions to the finance department
  4. Publishing targets without any supporting data

Explanation

Collaboration and visibility require transparent sharing of information so that stakeholders can contribute and hold the organization to account. Concealment, siloing, or unsupported targets contradict this guiding principle.

Question 22ITIL 4 Sustainability in Digital and IT

A cloud provider offers a carbon-aware scheduling feature that shifts workloads to times when grid energy is cleaner. Which sustainability benefit does this primarily deliver?

  1. Increasing the physical durability of servers
  2. Reducing the purchase cost of cloud services
  3. Reducing operational emissions by aligning compute demand with lower-carbon energy supply Correct answer.
  4. Eliminating the need for any emissions measurement

Explanation

Carbon-aware scheduling reduces operational emissions by timing flexible workloads to periods of lower-carbon electricity. It does not remove the need to measure, is not primarily a cost tool, and does not affect hardware durability.

Question 23ITIL 4 Sustainability in Digital and IT

Which statement correctly describes the difference between sustainability governance and sustainability operations?

  1. Governance sets direction, accountability, and policy, while operations executes day-to-day sustainability activities Correct answer.
  2. Governance applies only to external reporting
  3. Governance executes daily tasks, while operations sets policy
  4. Both terms describe the same set of activities

Explanation

Governance establishes the strategic direction, policies, and accountability for sustainability, while operations carries out the routine activities that deliver against those commitments. They are complementary but distinct levels of activity.

Question 24ITIL 4 Sustainability in Digital and IT

Why should sustainability criteria be included in procurement and sourcing decisions for IT services?

  1. They guarantee the lowest possible purchase price
  2. They influence the environmental and social impacts of the supply chain and create incentives for suppliers to improve Correct answer.
  3. They eliminate all sustainability risks immediately
  4. They remove the need for contract management

Explanation

Embedding sustainability criteria in procurement shapes supply chain impacts and signals expectations to suppliers, driving improvement. It does not guarantee lower prices, replace contract management, or eliminate risks outright.

Question 25ITIL 4 Sustainability in Digital and IT

Which example best demonstrates applying the 'think and work holistically' guiding principle to sustainability?

  1. Setting a target for one department without linking it to organizational goals
  2. Purchasing offsets without reducing emissions
  3. Recognizing that reducing travel emissions through remote work may shift impacts to home energy use and digital infrastructure Correct answer.
  4. Optimizing a single data centre's power usage without considering the wider service

Explanation

Holistic thinking considers the whole system and unintended consequences, such as rebound effects from shifting work patterns. Narrow optimization, isolated targets, and offset-only approaches fail to account for system-wide interactions.

Question 26ITIL 4 Sustainability in Digital and IT

Which ITIL 4 component is defined as a set of organizational resources designed for performing work or accomplishing an objective?

  1. A value stream
  2. A guiding principle
  3. A service offering
  4. A practice Correct answer.

Explanation

In ITIL 4 a practice is a set of organizational resources designed for performing work or accomplishing an objective, and sustainability work is organized through practices such as supplier management and measurement and reporting.

Question 27ITIL 4 Sustainability in Digital and IT

Which term describes the ability of an organization to continue operating and delivering value over the long term across environmental, social and economic dimensions?

  1. Sustainability Correct answer.
  2. Governance
  3. Resilience
  4. Service continuity

Explanation

Sustainability refers to the ability to endure and continue over the long term, balancing environmental, social and economic concerns so that value is not undermined for future stakeholders.

Question 28ITIL 4 Sustainability in Digital and IT

Which three dimensions are commonly used to structure sustainability objectives for a digital service?

  1. Availability, capacity and continuity
  2. Cost, quality and speed
  3. Strategy, design and transition
  4. Environmental, social and economic Correct answer.

Explanation

Sustainability is usually framed through environmental, social and economic pillars, and ITIL 4 guidance expects objectives to reflect all three rather than a single dimension.

Question 29ITIL 4 Sustainability in Digital and IT

Which ITIL 4 practice is most directly concerned with aligning an organization's suppliers and partners to agreed sustainability commitments?

  1. Deployment management
  2. Incident management
  3. Service desk
  4. Supplier management Correct answer.

Explanation

Supplier management ensures that the organization's suppliers and their performance are managed appropriately, which includes embedding sustainability clauses and monitoring supplier commitments.

Question 30ITIL 4 Sustainability in Digital and IT

In ITIL 4, what is the main purpose of the 'continual improvement' practice in a sustainability programme?

  1. To design the technical architecture of low-carbon data centres
  2. To negotiate sustainability terms with regulators
  3. To record every sustainability incident for audit purposes
  4. To identify and manage improvements to products, services and practices so sustainability performance keeps advancing Correct answer.

Explanation

Continual improvement aligns the organization's practices and services with changing needs by identifying and managing improvements, which is how sustainability targets translate into repeated, measurable progress.

Question 31ITIL 4 Sustainability in Digital and IT

An organization wants sustainability to be considered whenever changes are assessed. Which practice should be engaged to add environmental and social criteria to change evaluation?

  1. Service catalogue management
  2. Change enablement Correct answer.
  3. Knowledge management
  4. Problem management

Explanation

Change enablement assesses changes and authorizes them, so it is the practice where sustainability criteria can be added to the risk and impact evaluation of each change.

Question 32ITIL 4 Sustainability in Digital and IT

Which statement best describes the purpose of the 'measurement and reporting' practice in relation to sustainability?

  1. It replaces the need for sustainability governance
  2. It defines and operates a measurement system so sustainability performance can be tracked and reported credibly Correct answer.
  3. It sets the price of carbon offsets
  4. It guarantees that sustainability targets will be met

Explanation

Measurement and reporting supports the improvement and performance of products, services and practices by providing a system of measurement and reporting, which gives sustainability claims an auditable basis.

Question 33ITIL 4 Sustainability in Digital and IT

Which guiding principle suggests an organization should see sustainability effects across the whole system rather than in isolated components?

  1. Focus on value
  2. Progress iteratively with feedback
  3. Think and work holistically Correct answer.
  4. Start where you are

Explanation

Think and work holistically means understanding how all parts of the organization interrelate, which matters because sustainability impacts often appear elsewhere in the system than where the decision was made.

Question 34ITIL 4 Sustainability in Digital and IT

A service team is told to reduce the energy used by batch reporting. Which action best reflects the principle 'start where you are'?

  1. Replace the whole reporting platform with a new vendor product immediately
  2. Outsource the reporting team to a third party
  3. Suspend all reporting until a sustainability strategy is approved
  4. Measure current consumption of the existing batch jobs and optimize them before buying new hardware Correct answer.

Explanation

Start where you are means considering what already exists and reusing or improving it rather than starting over, so measuring and tuning existing batch jobs uses current capability before new investment.

Question 35ITIL 4 Sustainability in Digital and IT

Which factor is most characteristic of the 'organizations and people' dimension when pursuing sustainability?

  1. Cultural norms, roles and skills that shape sustainable behaviour Correct answer.
  2. The number of servers in a data centre
  3. The bandwidth of network links
  4. Grid carbon intensity of the hosting region

Explanation

The organizations and people dimension covers structure, culture, roles and skills, so sustainability depends on whether people understand their responsibilities and are motivated to act on them.

Question 36ITIL 4 Sustainability in Digital and IT

An organization must report sustainability data to a regulator and to internal boards. Which consideration is most important when designing the measurement approach?

  1. Delegating all reporting to the marketing department
  2. Using only data that makes performance look favourable
  3. Collecting every available data point regardless of purpose
  4. Defining indicators and data sources before collecting figures Correct answer.

Explanation

Credible reporting depends on first defining which indicators matter, how they are calculated and where the data comes from, so that figures are consistent, comparable and defensible.

Question 37ITIL 4 Sustainability in Digital and IT

Which practice ensures that sustainability requirements are embedded in the design of new and changed services?

  1. Service validation and testing
  2. Service desk
  3. Design and transition Correct answer.
  4. Relationship management

Explanation

Design and transition ensures products and services meet stakeholder expectations for quality, cost and time to market, which is where sustainability requirements must be built in rather than added later.

Question 38ITIL 4 Sustainability in Digital and IT

Which statement best explains why the 'information and technology' dimension matters for sustainability reporting?

  1. It determines the carbon footprint of the organization's offices
  2. It provides the systems and data quality on which measurement and disclosure depend Correct answer.
  3. It guarantees that suppliers will meet their commitments
  4. It replaces the need for organizational culture change

Explanation

The information and technology dimension covers the information, knowledge and technologies needed to manage services, so reliable sustainability disclosure depends on the quality and integration of the underlying data systems.

Question 39ITIL 4 Sustainability in Digital and IT

A team must choose between two equally performing servers, one from a supplier with verified renewable energy use and one without. Which decision criterion is most aligned with sustainability guidance?

  1. Total environmental impact across the life cycle alongside cost and performance Correct answer.
  2. Supplier brand recognition
  3. Shortest delivery lead time
  4. Lowest purchase price only

Explanation

Sustainability guidance calls for considering environmental and social impact across the whole life cycle together with cost and performance, so verified energy use should be weighed alongside the other criteria.

Question 40ITIL 4 Sustainability in Digital and IT

Which outcome best demonstrates that a sustainability improvement has been successfully realized?

  1. A vendor has been invited to present a green product roadmap
  2. A measured reduction in energy per transaction is confirmed after the change Correct answer.
  3. A sustainability policy document has been approved by leadership
  4. A project team has been formed to study sustainability

Explanation

Realized value is demonstrated by measurable change in outcomes, not by activity or documentation, so a confirmed reduction in energy per transaction shows the improvement achieved its intended effect.

Question 41ITIL 4 Sustainability in Digital and IT

How does the 'focus on value' principle apply when a sustainability initiative adds cost to a service?

  1. The initiative should be cancelled whenever cost rises
  2. The initiative should be justified by the value it creates for stakeholders, including avoided harm Correct answer.
  3. Cost should be ignored because sustainability always outweighs it
  4. Value should be assessed only through the price customers pay

Explanation

Focus on value requires understanding what stakeholders truly value, so added cost must be weighed against benefits such as reduced environmental harm, compliance and reputation rather than rejected automatically.

Question 42ITIL 4 Sustainability in Digital and IT

A service provider wants to reduce e-waste. Which approach best applies the 'keep it simple and practical' principle?

  1. Introduce a single clear device take-back process with defined responsibilities Correct answer.
  2. Add sustainability approval to every individual password reset
  3. Commission a multi-year study before any device is recovered
  4. Create a separate sustainability process for every device type and location

Explanation

Keep it simple and practical means using the minimum number of steps to achieve the outcome, so one clear take-back process with defined responsibilities is more likely to be followed than many overlapping ones.

Question 43ITIL 4 Sustainability in Digital and IT

Which risk treatment is most appropriate when an organization cannot eliminate the environmental impact of a legacy system in the short term?

  1. Transfer all responsibility by renaming the system
  2. Accept and monitor the residual impact while planning a longer-term transition Correct answer.
  3. Ignore the impact because it cannot be removed
  4. Close the service immediately without a migration plan

Explanation

Risk management allows residual risk to be accepted when treatment is not immediately feasible, provided it is recorded, monitored and addressed through a planned transition.

Question 44ITIL 4 Sustainability in Digital and IT

Which statement best describes how sustainability should be reflected in the 'plan' value stream activity?

  1. Sustainability is addressed only after services are live
  2. Sustainability objectives and constraints are considered when setting direction and priorities Correct answer.
  3. Sustainability is delegated entirely to external auditors
  4. Sustainability is recorded only in the service desk tool

Explanation

The plan activity sets the direction, priorities and objectives for the organization, so sustainability commitments must be reflected there to influence the rest of the value stream.

Question 45ITIL 4 Sustainability in Digital and IT

A sustainability report shows a target was missed. Which action best reflects the principle 'progress iteratively with feedback'?

  1. Review the feedback, adjust the approach in small steps and measure again Correct answer.
  2. Wait a full year before reviewing any data
  3. Abandon the target and set a lower one
  4. Remove the indicator from future reports

Explanation

Progress iteratively with feedback means using feedback to make small, frequent adjustments, so a missed target should trigger review, adjustment and re-measurement rather than abandonment or concealment.

Question 46ITIL 4 Sustainability in Digital and IT

An organization wants sustainability to influence decisions across procurement, design, operations and reporting. Which mechanism is most effective for achieving this alignment?

  1. A dedicated sustainability team that approves every operational task
  2. A voluntary pledge with no reporting requirement
  3. Sustainability criteria embedded in the governance and decision-making forums of each practice Correct answer.
  4. A single annual awareness email

Explanation

Embedding criteria in existing governance and decision-making forums makes sustainability part of routine choices across practices, which is more durable than one-off communication or central bottlenecks.

Question 47ITIL 4 Sustainability in Digital and IT

Two options reduce emissions equally, but one also improves accessibility for users with disabilities. Which evaluation best reflects the three pillars of sustainability?

  1. Defer the decision until a purely financial metric is available
  2. Prefer the option that delivers both environmental and social benefit when economic cost is comparable Correct answer.
  3. Choose the option with the lowest emissions and disregard social effects
  4. Choose the cheaper option regardless of accessibility

Explanation

The three pillars require balancing environmental, social and economic outcomes, so where environmental benefit is equal, the option that also improves social outcomes is preferable if cost is comparable.

Question 48ITIL 4 Sustainability in Digital and IT

Why does the ITIL 4 principle 'collaborate and promote visibility' matter for supplier sustainability claims?

  1. It ensures claims are transparent and can be verified through shared information Correct answer.
  2. It transfers legal liability for claims to the customer
  3. It guarantees suppliers will reduce emissions annually
  4. It removes the need for contractual sustainability terms

Explanation

Collaboration with transparency allows sustainability claims to be checked against shared data, which reduces the risk of unverified or overstated environmental statements in the value chain.

Question 49ITIL 4 Sustainability in Digital and IT

A digital service's sustainability performance depends on grid carbon intensity that varies hourly. Which measurement design is most appropriate?

  1. An annual average of total electricity use only
  2. A one-off estimate made at service design
  3. Time-resolved measurement of consumption combined with location-based carbon intensity Correct answer.
  4. A customer satisfaction survey used as a proxy

Explanation

When carbon intensity varies over time, meaningful measurement requires matching consumption to the carbon intensity at the time and place of use, which annual totals or one-off estimates cannot reveal.

Question 50ITIL 4 Sustainability in Digital and IT

An organization sets a carbon reduction target that its suppliers largely determine. Which governance arrangement is most defensible?

  1. Exclude supplier emissions from the reported figure
  2. Assign shared targets and reporting obligations across internal owners and key suppliers Correct answer.
  3. Hold the IT function solely accountable while suppliers remain unengaged
  4. Rely on suppliers to self-report without any verification

Explanation

Where outcomes depend on third parties, accountability must be distributed through shared targets and reporting obligations, supported by verification, so that responsibility matches the ability to influence the result.
