Environmental, Social and Economic Challenges in Design

Designers have a responsibility to consider the wider impact of their products on the environment, society and the economy. This lesson covers the environmental, social and economic challenges in design as required by AQA GCSE Design and Technology (8552), Section 3.3. These topics are frequently tested on Paper 2 and should also be addressed in your NEA.

Environmental Challenges

Climate Change and Global Warming

The manufacture, use and disposal of products all contribute to greenhouse gas emissions (mainly CO2, methane and nitrous oxide), which drive global warming.

Stage	Environmental Impact
Raw material extraction	Mining, logging and drilling damage habitats and release CO2
Manufacturing	Energy use (often from fossil fuels) produces CO2; chemical processes cause pollution
Transportation	Shipping products globally burns fossil fuels
Use	Electrical products consume energy; products may release harmful substances
Disposal	Landfill produces methane; incineration releases CO2 and toxins

Deforestation

Deforestation — the clearing of forests for timber, agriculture or development — has severe consequences:

• Loss of biodiversity (habitats destroyed).
• Reduced CO2 absorption (trees are carbon sinks).
• Soil erosion and flooding.
• Indigenous communities displaced.

Design response: Use timber from FSC-certified (Forest Stewardship Council) sustainable forests. Choose fast-growing timbers (bamboo, pine) over slow-growing hardwoods (mahogany, teak). Use engineered boards (MDF, plywood) that make efficient use of timber.

Pollution

Type	Source	Example
Air pollution	Factory emissions, vehicle exhaust	Smog in industrial cities
Water pollution	Textile dyeing discharge, chemical waste from factories	River pollution near textile mills in Bangladesh
Land pollution	Landfill waste, illegal dumping	Plastic waste in developing countries
Microplastic pollution	Synthetic textiles releasing fibres during washing	Microfibres in oceans from polyester clothing

AQA Exam Tip: When discussing environmental challenges, always link the issue to a specific design response. For example: "Microplastic pollution from polyester clothing can be reduced by designing garments from natural fibres or by including a microfibre-catching filter in washing machine designs."

The 6 Rs of Sustainability

The 6 Rs framework helps designers minimise environmental impact:

R	Meaning	Example
Reduce	Use less material, energy or packaging	Concentrated washing liquid (smaller bottle, less water in transport)
Reuse	Design products for multiple uses	Reusable water bottles replacing single-use plastic bottles
Recycle	Design products so materials can be recovered and reprocessed	Using recycled aluminium for drinks cans (95% less energy than virgin aluminium)
Refuse	Avoid using harmful or unnecessary materials	Refusing single-use plastic straws; using paper alternatives
Rethink	Completely reconsider how a product or service works	Streaming music instead of manufacturing physical CDs
Repair	Design products that can be easily fixed	Fairphone — modular smartphone designed for easy component replacement

Social Challenges

Fair Trade

Fair Trade is a movement that ensures producers in developing countries receive a fair price for their goods, safe working conditions and community investment.

Fair Trade Principle	Benefit
Fair prices	Farmers and workers earn enough to cover the cost of sustainable production
Safe working conditions	No child labour, safe factories, reasonable hours
Community development	Premium funds invested in schools, clean water, healthcare
Environmental standards	Restrictions on harmful chemicals, encouragement of organic practices

Real-world example: Fair Trade cotton is used by brands like People Tree and Patagonia. The cotton is grown without harmful pesticides, and farmers receive a guaranteed minimum price plus a social premium.

Planned Obsolescence

Planned obsolescence is when products are deliberately designed to have a limited lifespan, forcing consumers to buy replacements.

Type	Description	Example
Contrived durability	Product designed to break after a set period	Printer cartridges with built-in chip that stops them working after a certain number of pages
Perceived obsolescence	Fashion or styling changes make the product feel outdated	Annual smartphone releases with minor cosmetic changes
Technological obsolescence	Software updates no longer support older hardware	Older iPhones slowed down by iOS updates

Design response: The Right to Repair movement and EU regulations are pushing manufacturers to make products more repairable and longer-lasting. Fairphone and Framework Laptop are examples of companies designing against planned obsolescence.

AQA Exam Tip: Planned obsolescence is a frequent exam topic. Be ready to define it, give examples and discuss whether it is justified (e.g. safety updates vs wasteful design).

Economic Challenges

Cost of Sustainable Materials

Sustainable and ethically sourced materials often cost more than conventional alternatives:

Material	Conventional Cost	Sustainable Alternative	Cost Difference
Cotton	Standard cotton	Organic / Fair Trade cotton	20–50% more expensive
Timber	Non-certified tropical hardwood	FSC-certified timber	10–30% more expensive
Plastic	Virgin plastic	Recycled plastic (rPET)	Variable; sometimes comparable
Energy	Fossil fuels	Renewable energy (solar, wind)	Initial investment higher, long-term costs lower

Balancing Cost and Sustainability

Designers face a tension between:

• Keeping costs low to make products affordable and competitive.
• Using sustainable materials and processes to reduce environmental impact.

Strategies to manage this tension include:

• Design for manufacture (DFM) — simplifying designs to reduce waste and production steps.
• Modular design — using standard components across multiple products to achieve economies of scale.
• Life-cycle thinking — considering the total cost of ownership (including energy use and disposal), not just the purchase price.

Life Cycle Assessment (LCA)

A Life Cycle Assessment evaluates the total environmental impact of a product from cradle to grave (or cradle to cradle).

Stage	What Is Assessed
Raw materials	Extraction, processing, transportation
Manufacturing	Energy use, waste, emissions, water use
Distribution	Packaging, transportation, storage
Use	Energy consumption, maintenance, consumables
End of life	Disposal (landfill, incineration), recycling, composting

Example: LCA of a Plastic Water Bottle vs a Reusable Steel Bottle

Factor	Single-Use Plastic Bottle	Reusable Steel Bottle
Raw materials	Petroleum (non-renewable)	Steel and stainless steel (recyclable)
Manufacturing energy	Low per unit	Higher per unit
Use phase	Single use, then discarded	Used hundreds of times
End of life	Often landfilled; takes 450 years to decompose	Recyclable indefinitely
Overall impact	High if not recycled	Lower after approximately 50 uses
