What this dot point is asking
CCEA expects you to design for sustainability using the 6 Rs, to explain life-cycle assessment (cradle to grave), and to discuss a designer's social, moral and environmental responsibilities. Applying the 6 Rs to a named product and explaining LCA stages are standard questions.
The answer
The 6 Rs
Life-cycle assessment
Designer responsibilities
Worked example: improving a product's sustainability
Examples in context
Example 1. Fairphone. A smartphone designed for easy repair and modular upgrade, with ethically sourced materials, directly applies Repair, Reuse and responsible sourcing against the throwaway norm of the industry.
Example 2. Aluminium recycling. Recycling aluminium uses about 5 percent of the energy of producing it from ore, a striking illustration of embodied energy and why design for recycling matters at end of life.
Try this
Q1. List the 6 Rs of sustainability. [3 marks]
- Cue. Rethink, Refuse, Reduce, Reuse, Repair, Recycle.
Q2. Name two stages a life-cycle assessment considers. [2 marks]
- Cue. Any two of raw material extraction, manufacture, distribution/transport, use, disposal/end of life.
Q3. Explain why "reduce" is generally better for the environment than "recycle". [2 marks]
- Cue. Reducing avoids using the material and energy in the first place, whereas recycling still consumes energy to collect and reprocess the material.

CCEA 20206 marksUsing the 6 Rs of sustainability, explain how a designer could reduce the environmental impact of a plastic drinks bottle.Show worked answer →
The 6 Rs are Rethink, Refuse, Reduce, Reuse, Repair, Recycle. Applied to a drinks bottle:
- Rethink: redesign the product or system, for example offer a refillable bottle and public refill points rather than single-use bottles.
- Refuse: avoid unnecessary material, for example refuse to over-package or to use a non-recyclable multilayer plastic.
- Reduce: use less material per bottle (lightweighting, thinner walls) and less energy in manufacture.
- Reuse: design the bottle to be refilled many times rather than discarded after one use.
- Repair: less relevant to a bottle, but a sports bottle could have a replaceable lid/seal so the whole bottle is not thrown away.
- Recycle: use a single, clearly labelled recyclable polymer (e.g. PET, type 1) and a removable label, so it can be reprocessed.
Markers reward naming the 6 Rs and applying at least four meaningfully to the bottle, not just listing them. The strongest answers show Rethink/Reduce/Reuse cut impact more than recycling alone.
CCEA 20184 marksExplain what is meant by a life-cycle assessment (LCA) and state two stages it considers.Show worked answer →
A life-cycle assessment (LCA) is a systematic analysis of the total environmental impact of a product across its whole life, from raw materials to final disposal ("cradle to grave"), so the true impact can be judged and reduced.
Stages it considers include: raw material extraction and processing; manufacture/production; distribution and transport; use (energy/water consumed in service); and disposal / end of life (landfill, recycling, incineration). Any two valid stages earn the marks.
Markers want the cradle-to-grave idea (impact across the whole life) and two correctly named stages.
