Cambridge O Level Commerce: Sustainability and Ethics — Revision Notes (7100)

Sustainability and ethics is the last topic in Cambridge O Level Commerce (7100, 2026-2028). It asks how businesses can keep trading without damaging the environment for future generations (6.1), how they should behave morally, including through fair trade (6.2), and why consumers need protection and how complaints are settled (6.3). It is short, but questions are applied, so practise linking each idea to a named business.

For full explanations use the sustainability and ethics study guide; practise with the sustainability and ethics practice questions.

Syllabus coverage (7100, 2026-2028)

Ref	Content
6.1.1	Purpose of sustainability in the supply chain
6.1.2	Actions to improve sustainability
6.2.1	Meaning of ethics; role of fair trade; misleading advertising; harmful disposal of products
6.3	Reasons for consumer protection; actions by buyers and sellers to resolve complaints

What is sustainability for in the supply chain?

The syllabus defines its purpose as making commercial processes eco-friendly and environmentally responsible for future generations. Every stage of the supply chain - sourcing materials, making, moving, selling and disposing of goods - can be made more sustainable.

Nine sustainability actions, stage by stage

Supply chain stage	Action
Sourcing	Use sustainable materials in production; water stewardship
Moving goods	Implement sustainable logistics
Selling	Sell eco-friendly products; reduce packaging
After the sale	Reduce the need for returns and exchanges; offer free repair services; offer digital resale marketplaces
Throughout	Recycle and reduce waste

Why would a business do this? Lower long-term costs (less energy, water and waste), better reputation, customer loyalty, meeting legal requirements, and access to customers who choose eco-friendly brands. Why might it hesitate? Higher short-term costs, possible higher prices, and time to change suppliers and systems.

Worked example. A furniture maker switches to certified sustainable timber and offers a free repair service.

• Benefit: forests are protected for future supply; repairs keep furniture in use and build loyalty.
• Cost: certified timber is dearer; repair staff must be paid.
• Judgement: worthwhile if customers will pay slightly more for durable, responsibly made furniture.

What does ethics mean in commerce?

Ethics are the moral principles that guide behaviour - doing what is right, not just what is legal or profitable.

Fair trade

• Producers, often small farmers in low-income countries, receive a fair price and better working conditions.
• Role in commerce: gives retailers ethically sourced goods to sell, gives shoppers a way to support producers, and helps build long-term, reliable supply relationships.

Unethical practices named in the syllabus

Issue	What it looks like	Why it matters
Misleading advertising	False claims, hidden charges, edited images, fake “sale” prices	Consumers buy on false information; trust and reputation suffer
Harmful disposal of products	Dumping waste, unsafe disposal of batteries, electronics or chemicals	Pollution, health risks, fines and boycotts

Why do consumers need protection?

• Unequal knowledge: sellers know more about the product.
• Unequal power: a single consumer cannot easily take on a large company.
• Safety: faulty goods can cause injury.
• Value: consumers should get goods as described and fit for use.
• Honesty: protection against misleading advertising and unfair pricing.

How are consumer complaints resolved?

Steps for the buyer

1. Stop using the faulty item and keep the receipt or proof of purchase.
2. Contact the seller quickly, explaining the fault and what you want.
3. If unresolved, write to the manager or head office.
4. Seek help from a consumer organisation or regulator.
5. Use the courts as a last resort.

Steps for the seller

1. Respond quickly and politely; record the complaint.
2. Offer a refund, replacement or repair.
3. Add goodwill (apology, voucher) to keep the customer.
4. Investigate and correct the cause, such as a faulty batch or unclear product description.

How do sustainability, ethics and consumer protection connect?

	Sustainability (6.1)	Ethics (6.2)	Consumer protection (6.3)
Main concern	The environment and future generations	Doing what is morally right	Fair treatment of buyers
Who benefits most	Society and future customers	Producers, workers, communities	Consumers
Typical exam example	Reducing packaging	Fair trade sourcing	Refund for a faulty product
Typical evaluation point	Short-term cost vs long-term saving	Higher cost vs stronger reputation	Cost of refunds vs customer loyalty

The three overlap. Harmful disposal of products is an ethical issue and a sustainability problem; misleading advertising is an ethical issue and a reason why consumers need protection. In longer answers, showing these links earns analysis marks.

Worked example: a complaint handled two ways. A customer’s new blender breaks after three days.

• Shop A refuses to help. The customer posts a bad review, tells friends and may contact a consumer organisation - the shop loses future sales.
• Shop B apologises, replaces the blender and returns the faulty one to the manufacturer for repair or recycling. The customer stays loyal, and the faulty item is not simply thrown away. Shop B’s approach is fairer to the consumer, better for its reputation and more sustainable.

Common mistakes and exam traps

• Defining sustainability without “future generations”.
• Giving “fair trade” as cheaper goods - it usually means paying producers more.
• Mixing up ethics and law: an action can be legal but still unethical.
• Writing a generic list of complaint steps without applying them to the scenario.
• Ignoring the cost side when asked to evaluate a sustainability action.

Frequently asked questions

What is water stewardship? Using water responsibly in production - cutting use, treating waste water and protecting shared supplies for local communities.

Why might a business offer a digital resale marketplace? It keeps used products in circulation instead of being thrown away and can build customer loyalty, which supports sustainability.

What is the first thing a buyer should do with a faulty product? Keep the proof of purchase and contact the seller promptly to ask for a refund, repair or replacement.
