ICAEW SE Concepts and significance of sustainability: practice questions with answers

Question 1

The board of Hollinbrook Water, a regional water company, is choosing how much water to draw each year from an underground aquifer that supplies 400,000 homes. Which option is most consistent with the Brundtland definition of sustainable development?

1. A Set the extraction rate so that the aquifer recharges as fast as it is drawn down, while still meeting current household demand
2. B Extract at the maximum licensed rate now to keep bills low, on the basis that future customers will be able to rely on new technology
3. C Stop all extraction until the aquifer has fully recovered, even though current households would be left without a supply
4. D Choose whichever rate gives the highest return to shareholders this year, as current profits will fund future investment

Show the answer

Answer: A. The Brundtland Report (Our Common Future, 1987) defines sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Both halves matter. A decision must meet present needs (so a complete shutdown fails) and must not run down the resources future generations rely on (so over-extraction fails). Extracting at no more than the recharge rate satisfies both.

Question 2

Sorrelby Foods, a UK bakery chain, wants to show in its annual report how it contributes to the UN Sustainable Development Goals. Which approach is most appropriate?

1. A Report against all 17 goals equally, giving each the same space so that no stakeholder feels its priorities have been ignored
2. B Focus on the goals linked to its main impacts, such as food waste, and set measurable targets to show its contribution
3. C Choose the goals where its existing activities already look strongest and report only the positive progress against them
4. D Use the SDGs in place of its UK legal reporting duties, since the goals were agreed by every UN member state

Show the answer

Answer: B. Businesses use the SDGs best when they prioritise the goals connected to their most significant impacts, set measurable targets, and report progress honestly, including where performance is weak.

Reporting equally on all 17 goals, or picking only flattering ones, does not show a real contribution. The SDGs are a voluntary framework, so they sit alongside, not instead of, legal reporting duties.

Question 3

The sustainability report of Dunholt Cement opens with the sentence: 'We now operate in the Anthropocene.' What is the writer signalling?

1. A The planet has entered a period of natural climate cooling that is not linked to human activity
2. B Economic growth has now been permanently separated from the use of natural resources
3. C World population has peaked and human pressure on the environment is now falling
4. D Human activity has become a dominant influence on the Earth's climate and ecosystems

Show the answer

Answer: D. The Anthropocene is a proposed name for the current period of Earth's history in which human activity is a dominant influence on the climate and the environment, for example through greenhouse gas emissions, land-use change and biodiversity loss.

For a business, using the term signals that its own activities form part of that human pressure, which is why the idea underpins frameworks such as planetary boundaries.

Question 4

A director of Grisedale Quarries argues that draining a wetland to extend the quarry is acceptable, because the profits will be reinvested in new plant and a training academy that will be worth more than the wetland. Which view of sustainability does this argument reflect?

1. A Strong sustainability, because it keeps the company's total stock of capital at least constant over time
2. B Weak sustainability, because it assumes that natural capital can be replaced by manufactured and human capital
3. C Circular economy thinking, because the profits from the quarry are reinvested back into the company's own business
4. D Doughnut economics, because the training academy will strengthen the social foundation

Show the answer

Answer: B. The <IR> Framework describes six capitals: financial, manufactured, intellectual, human, social and relationship, and natural.

- Weak sustainability: capitals are substitutable. Losing natural capital is acceptable if it is replaced by an equal or greater amount of other capital, such as new plant (manufactured) or skills (human).
- Strong sustainability: some natural capital is critical and cannot be substituted, so it must be preserved regardless of the gains elsewhere.

The director's argument depends on substitution, so it reflects weak sustainability.

Question 5

Brisworth Electronics depends on several metals that are mined in only a few countries. Prices have risen sharply as global demand grows and the richest ore deposits are worked out. Which global sustainability trend is Brisworth most directly exposed to?

1. A Population decline
2. B Biodiversity loss
3. C Resource scarcity
4. D Rising income inequality

Show the answer

Answer: C. Resource scarcity arises when demand for finite resources (metals, minerals, fresh water, fertile land) grows faster than accessible supply. It shows up as rising and volatile prices, supply disruption and geopolitical risk where supply is concentrated in a few countries.

Businesses respond by diversifying suppliers, using less material per product, substituting materials, and recovering materials through recycling and circular design.

Question 6

Marlowe Retail operates stores across regions where the gap between high and low incomes has widened in recent years. Which is the most likely way this trend affects the business?

1. A Weaker spending by lower-income customers and closer scrutiny of the gap between executive and staff pay
2. B No effect at all, because inequality is a matter for governments and has no bearing on business performance
3. C Lower wage costs in every region, which will always improve the retailer's long-term profitability
4. D A rise in Marlowe's Scope 1 emissions, because inequality increases the energy used by its stores

Show the answer

Answer: A. Inequality (of income, wealth and opportunity) is one of the global sustainability trends businesses face. Its effects include:
- weaker or more polarised consumer demand;
- social unrest and political instability;
- closer scrutiny of pay ratios, fair wages and tax behaviour, which affects reputation and the licence to operate;
- reduced access to skills where education and opportunity are unequal.

It is therefore a business issue as well as a policy issue.
