Good design considers more than whether something works — it weighs its environmental impact (materials sourced sustainably, energy used in production, what happens when the product is eventually thrown away) and ethical impact (were workers treated and paid fairly, is the product safe, does it genuinely benefit its users). Designers increasingly use strategies like choosing recycled or renewable materials, designing for durability and repairability (rather than planned obsolescence, where products are designed to wear out or become outdated quickly), and considering a product's full lifecycle from raw material to eventual disposal or recycling.
Example
A phone designed with a sealed, non-removable battery is cheaper and slimmer to manufacture, but forces users to replace the whole device once the battery degrades — generating more electronic waste. A phone designed with an easily replaceable battery costs slightly more to manufacture but can last years longer, reducing its overall environmental footprint.
Key terms
Sustainability:
Meeting present needs without compromising the ability of future generations to meet theirs.
Planned obsolescence:
Designing a product to become outdated or stop working sooner than necessary.
Questions
1. Sustainable design considers:
Environmental impact, including materials and eventual disposal
Only how a product looks
Nothing about the environment
Only the cheapest possible option
2. Planned obsolescence means:
Designing a product to become outdated or fail sooner than necessary
Designing a product to last as long as possible
A type of recycling process
Something unrelated to product design
3. Ethical design considers:
Whether workers were treated and paid fairly
Only the final selling price
Nothing about how a product was made
Only how fast a product can be made
4. A product's full lifecycle includes:
Raw material to eventual disposal or recycling
Only the moment of purchase
Only the design phase
Nothing after manufacturing
5. Designing for repairability means:
Making a product easier to fix rather than replace
Making a product impossible to open
Designing a product to break quickly
Something unrelated to sustainability
6. A sealed, non-removable phone battery can lead to:
More electronic waste when the battery degrades
Less electronic waste overall
A phone that never needs replacing
No environmental impact at all
7. Using recycled or renewable materials is an example of:
A sustainable design strategy
An unrelated manufacturing step
A strategy that always increases waste
Something with no environmental benefit
8. Why might a product designed for durability and repairability have a smaller overall environmental footprint than one designed to be replaced often?
A longer-lasting product reduces the total resources and waste generated over time compared to frequent replacements
Durability and repairability always increase a product's environmental impact
Products designed to be replaced often always have a smaller environmental footprint
Product lifespan has no connection to environmental impact
9. Why might a company choose planned obsolescence despite its negative environmental impact?
It can increase sales by encouraging customers to purchase replacement products more frequently
Planned obsolescence always reduces a company's profit
Companies never have any commercial incentive for planned obsolescence
This design strategy has no connection to sales or profit
10. Why is considering a product's full lifecycle (not just its use) important for genuinely sustainable design?
A product with a low impact during use could still have a high environmental cost in production or disposal
Only the moment of use matters for a product's environmental impact
A product's environmental impact ends as soon as it is manufactured
Considering the full lifecycle never changes how sustainable a product actually is
11. Why might ethical considerations (like fair worker pay) be relevant to a technology or design class, not just a business or ethics class?
Every designed product involves real people in its production, and designers can influence these outcomes through their choices
Ethical considerations are entirely irrelevant to how a product is designed
Worker treatment has no connection to design decisions
Only businesses, never designers, have any influence over ethical production
12. Why might a product made from a single, easily recyclable material be more sustainable than one made from many mixed materials glued together?
Mixed materials are often much harder or impossible to separate and recycle effectively at the end of a product's life
Mixed materials are always easier to recycle than a single material
Material choice has no bearing on how recyclable a product ultimately is
Recyclability is never affected by how many materials are combined
13. Why might designing a product to be easily disassembled support both repairability and recycling?
Easy disassembly allows individual parts to be fixed, replaced or separated for proper recycling, rather than the whole product being discarded
Disassembly design has no connection to repair or recycling outcomes
Products that are hard to take apart are always easier to recycle
Repairability and recyclability are entirely unrelated design goals
14. Why might a designer need to balance sustainability goals against cost and manufacturing practicality?
The most sustainable option isn't always the cheapest or easiest to manufacture at scale, requiring careful trade-offs
Sustainability goals never conflict with cost or manufacturing practicality
Cost and practicality should always be ignored in favour of sustainability
Balancing these factors has no real role in the design process
15. Why might legislation in some countries now require companies to make replacement parts (like batteries) more easily available to consumers?
It aims to counter planned obsolescence and reduce electronic waste by extending product lifespans
Such legislation has no connection to reducing waste or extending product life
Making parts available always increases a product's environmental impact
Governments have no legitimate interest in product repairability
16. Why might a company's claim that a product is "eco-friendly" need to be evaluated critically, considering its full lifecycle rather than just one feature?
A product could be efficient during use but still have significant environmental costs in its materials, manufacturing or disposal
Any single eco-friendly feature always guarantees a product is genuinely sustainable overall
Full lifecycle evaluation never changes how sustainable a product appears
Companies always accurately represent a product's complete environmental impact
17. Why might designing for disassembly and recycling be considered as important as choosing sustainable materials in the first place?
Even sustainably-sourced materials create waste if the product can't be properly separated and recycled at end of life
Only the choice of original material matters for a product's sustainability, not what happens afterward
End-of-life design has no bearing on a product's overall environmental impact
Materials sourced sustainably never need any consideration for disposal
18. Why might ethical design considerations sometimes create tension with a company's goal of minimising production costs?
Ensuring fair wages and safe working conditions can increase production costs compared to cutting corners on these standards
Ethical design considerations never have any effect on production cost
Minimising cost and ethical production are always perfectly aligned goals
Fair wages and safety standards have no bearing on manufacturing cost
19. A furniture brand advertises a chair as "sustainable" because it uses recycled plastic, but the chair is glued together in a way that makes it impossible to repair or recycle again at end of life. Why is this only a partial sustainability claim?
It addresses the material sourcing but ignores repairability and end-of-life recyclability — both important parts of a product's full lifecycle
Using any recycled material automatically makes a product fully sustainable regardless of other factors
Repairability and recyclability are irrelevant once a product uses recycled material
A single sustainable feature always represents the complete sustainability picture
20. Why might a government-imposed "right to repair" law, requiring companies to make spare parts and repair manuals available, directly address planned obsolescence?
It removes a key barrier (lack of parts/information) that companies could otherwise use to make products harder to repair and encourage replacement instead
Right to repair laws have no connection to planned obsolescence
Making repair information available always has no effect on product lifespan
Companies have no ability to influence how repairable their products are
21. Understanding sustainable and ethical design mainly helps you to:
Evaluate and make design choices that consider environmental and human impact beyond just function and cost
Assume a product's environmental impact ends once it is manufactured
Ignore how workers are treated in the production of designed products
Treat sustainability as unrelated to genuine, thoughtful design
