What are the three pillars of sustainability?
- A) Environmental, legal and technological
- B) Financial, manufactured and human
- C) Environmental, social and economic
- D) Governance, risk and compliance
Show answer & explanation
Answer: C) Environmental, social and economic
The three pillars of sustainability are environmental, social and economic. They reflect the idea that sustainability requires balancing the needs of the planet, people and the economy. Financial, manufactured and human are forms of capital rather than pillars.
Question 2
John Elkington's 'triple bottom line' encourages organisations to report on which three areas?
- A) People, planet and profit
- B) Price, product and place
- C) Profit, payroll and pensions
- D) Planning, performance and procurement
Show answer & explanation
Answer: A) People, planet and profit
The triple bottom line asks organisations to measure social (people), environmental (planet) and economic (profit) performance, rather than financial profit alone. The other options are marketing or operational terms with no link to sustainability reporting.
Question 3
Several fishing companies share access to the same sea. Each company increases its catch to maximise its own profits, and within a few years fish stocks collapse, harming all of them. Which concept does this illustrate?
- A) The circular economy
- B) Relative decoupling
- C) The tragedy of the commons
- D) The social licence to operate
Show answer & explanation
Answer: C) The tragedy of the commons
The tragedy of the commons arises when individuals acting in their own short-term interest overuse a shared resource, depleting it to everyone's detriment. It shows how inaction or uncoordinated action damages environmental sustainability and, in turn, economic sustainability. The other concepts do not describe the over-exploitation of a shared resource.
Question 4
An audit of a clothing retailer's overseas suppliers finds that workers have had their passports confiscated and are being forced to work excessive hours. Which pillar of sustainability is most directly affected?
- A) Environmental
- B) Economic
- C) Social
- D) Governance
Show answer & explanation
Answer: C) Social
Forced labour and the confiscation of identity documents are indicators of modern slavery, a human rights issue that falls under the social pillar. Governance is part of ESG but is not one of the three pillars of sustainability. The issue may have economic consequences for the retailer, but its primary impact is on people.
Question 5
Which of the following best describes economic sustainability?
- A) Maximising profit in the current year regardless of the impact on future periods
- B) The ability of an economy or organisation to support long-term economic activity and wellbeing without causing damage to the environment or society that undermines that activity
- C) Ensuring that a company never makes a loss in any financial year
- D) Keeping prices as low as possible for consumers at all times
Show answer & explanation
Answer: B) The ability of an economy or organisation to support long-term economic activity and wellbeing without causing damage to the environment or society that undermines that activity
Economic sustainability is about maintaining economic activity and prosperity over the long term, in a way that does not deplete the environmental and social resources on which the economy depends. Short-term profit maximisation can undermine long-term viability. Avoiding any annual loss or minimising prices are not definitions of economic sustainability.
Question 6
A chemicals factory discharges waste into a river, harming fishing businesses and communities downstream. The factory does not pay for this harm. In economic terms, what is this an example of?
- A) A negative externality
- B) A positive externality
- C) A sunk cost
- D) An opportunity cost
Show answer & explanation
Answer: A) A negative externality
A negative externality is a cost imposed on third parties that is not reflected in the price paid by the producer or consumer. Because the factory does not bear the cost of the pollution, the market under-prices its activity, which is one reason regulation and environmental taxes are used. A positive externality would be a benefit to third parties.
Question 7
A government plans to close coal mines to reduce emissions. It also funds retraining for miners and investment in new industries in mining towns. Which concept does this approach reflect?
- A) Greenwashing
- B) Weak sustainability
- C) A just transition
- D) Offshoring
Show answer & explanation
Answer: C) A just transition
A just transition means moving to a low-carbon economy in a way that is fair to workers and communities affected by the change. It recognises that environmental action has social and economic consequences, which must be managed. Retraining and regional investment address the social pillar alongside the environmental goal.
Question 8
Which of the following best illustrates the interconnection between the three pillars of sustainability?
- A) A company changes its auditor after a tender process
- B) Prolonged drought causes crop failures, which raise food prices and push vulnerable households into poverty
- C) A government increases the basic rate of income tax by one percentage point
- D) A retailer launches a new website to sell its products online
Show answer & explanation
Answer: B) Prolonged drought causes crop failures, which raise food prices and push vulnerable households into poverty
The drought is an environmental event that leads to an economic effect (higher food prices) and a social effect (increased poverty), showing how the pillars are linked. The other options describe events that do not demonstrate a chain of effects across the environmental, social and economic pillars.
Question 9
A company announces that it will pay all staff at least a voluntary 'living wage' benchmark rather than only the legal minimum wage. (In the UK, this voluntary benchmark is different from the statutory 'National Living Wage', which is itself a legal minimum rate.) How does a voluntary living wage differ from a minimum wage?
- A) A living wage is based on the income needed to cover a basic but acceptable standard of living, whereas a minimum wage is the legal floor set by law
- B) A living wage is set by the government each year, whereas a minimum wage is agreed between each employer and its staff
- C) A living wage applies only to directors, whereas a minimum wage applies to other employees
- D) A living wage is always lower than the minimum wage
Show answer & explanation
Answer: A) A living wage is based on the income needed to cover a basic but acceptable standard of living, whereas a minimum wage is the legal floor set by law
A voluntary living wage is a benchmark calculated from the cost of meeting basic needs, and is typically higher than the statutory minimum. The minimum wage is the legal floor that employers must pay and is set by government, not negotiated employer by employer. In the UK the statutory 'National Living Wage' is a legal minimum rate despite its name, which is why the stem distinguishes it from the voluntary benchmark. Paying a living wage supports social sustainability by reducing in-work poverty.
Question 10
Which statement best explains why delaying action on climate change can damage economic sustainability?
- A) Delay always reduces costs because technology will make all future action free
- B) Delay has no economic effect because climate change is solely an environmental issue
- C) Delay improves economic sustainability because it avoids any spending on low-carbon investment
- D) Delay tends to increase the eventual costs of adaptation and of a faster, more disruptive transition, and raises the risk of assets losing value before the end of their expected lives
Show answer & explanation
Answer: D) Delay tends to increase the eventual costs of adaptation and of a faster, more disruptive transition, and raises the risk of assets losing value before the end of their expected lives
The longer action is delayed, the greater the physical damage that must be adapted to and the sharper the policy changes needed later, both of which raise costs. A sudden transition can leave carbon-intensive assets stranded, damaging investors and the wider economy. Climate change is not purely environmental, and avoiding investment now does not remove the costs; it defers and usually increases them.
Question 11
The Gini coefficient is a common measure of economic inequality within a country. What does a Gini coefficient of zero indicate?
- A) Perfect inequality, with one person receiving all the income
- B) That the economy has zero growth
- C) That the country has no unemployment
- D) Perfect equality, with income shared equally by everyone
Show answer & explanation
Answer: D) Perfect equality, with income shared equally by everyone
The Gini coefficient ranges from 0 (perfect equality) to 1, or 100 if expressed as a percentage (perfect inequality). It measures how income or wealth is distributed, not growth or unemployment. Rising inequality is one of the key challenges to social and economic sustainability.
Question 12
Some sustainability models present the three pillars as three overlapping circles of equal size, while others present them as nested circles, with the economy inside society and society inside the environment. What is the main point made by the nested model?
- A) The economy depends on society, and both depend on the environment, so environmental limits constrain the other two pillars
- B) Each pillar is independent, so trade-offs between them are never needed
- C) The economy is the largest system and the environment is a small part of it
- D) Social issues are irrelevant once environmental targets are achieved
Show answer & explanation
Answer: A) The economy depends on society, and both depend on the environment, so environmental limits constrain the other two pillars
The nested model emphasises that the economy exists within society and that both rely on the natural environment. This means economic activity cannot be sustained if it breaches environmental limits, a view associated with strong sustainability. The overlapping-circles model treats the pillars as more equal and allows trade-offs, which the nested model challenges.
Question 13
A mining company has the legal permits it needs, but local communities strongly oppose its new mine and have organised blockades. Which concept best describes what the company lacks?
- A) A social licence to operate
- B) Planning permission
- C) A going concern basis
- D) Limited liability
Show answer & explanation
Answer: A) A social licence to operate
A social licence to operate is the ongoing acceptance of a company's activities by local communities and other stakeholders. It is not a legal document, so a company can have all permits yet still lack community support. Losing it can lead to delays, protests and reputational damage, showing how social sustainability affects business viability.
