What this dot point is asking
Eduqas C600 expects you to understand the ecological and social footprint of materials and products: the environmental impact (resource depletion, pollution, carbon footprint, waste) and the social impact (working conditions, communities, fair trade), and how design choices reduce both. In the written exam this is tested by explaining how a material choice lowers the ecological footprint and by defining the social footprint and the role of fair trade.
The ecological footprint
- Resource depletion: using up finite resources (metal ores, crude oil) that cannot be replaced.
- Pollution: harm from extraction (mining), processing (chemicals, emissions) and disposal (landfill, litter).
- Carbon footprint: the greenhouse gases released by the energy used to make, transport and use the product.
- Waste: offcuts in manufacture and the product itself at end of life.
The social footprint
Materials and products are often made far away, sometimes in poor working conditions or for low pay. The social footprint asks designers and companies to consider the people in the supply chain, not just the environment. Fair trade is the main tool: it guarantees producers a fair, stable price and decent conditions, and often reinvests a premium into the community (schools, healthcare). Ethical sourcing more broadly means avoiding materials linked to exploitation or conflict.
Reducing both footprints through design
Try this
Q1. State one way a material choice can lower a product's carbon footprint. [1 mark]
- Cue. Use a local material (less transport), a recycled material, or a lighter one (less energy to make and move).
Q2. Give one way fair trade improves the social footprint of a product. [1 mark]
- Cue. It guarantees producers a fair price and decent working conditions (and often reinvests in their community).

Eduqas C600 20194 marksExplain two ways the choice of material can reduce the ecological footprint of a product.Show worked answer →
A 4-mark Explain wants two developed material choices tied to a lower footprint.
Way 1, choose a recycled or recyclable material. Using recycled aluminium or a recyclable thermoplastic means less raw ore or oil is extracted and the material can be recovered at end of life, cutting resource depletion and waste.
Way 2, choose a renewable, responsibly sourced material. Using FSC-certified timber, which comes from forests that are replanted, means the resource is renewed and the carbon footprint is lower than a finite material, and it avoids deforestation.
Other valid points: choose a local material (less transport, lower carbon), or a lighter material (less material and lower transport energy). Markers reward two developed material choices each linked to a reduced footprint (less extraction, renewable, recyclable, local). Two bare statements cap the mark at two.
Eduqas C600 20224 marksExplain what is meant by the social footprint of a product, and how fair trade can improve it.Show worked answer →
A 4-mark Explain wants the social footprint defined and fair trade linked to it.
The social footprint is the effect of making and using a product on people: the working conditions of those who extract materials and assemble the product, the effect on their communities and local economies, and whether workers are paid and treated fairly.
Fair trade improves it by guaranteeing producers a fair, stable price and decent working conditions, and often investing a premium back into the community (schools, healthcare). So choosing fair-trade materials or components means the people who make the product are treated and paid fairly, improving the social footprint.
Markers reward: the social footprint is the human impact (working conditions, communities, fair pay), and fair trade guarantees fair prices and conditions and reinvests in communities. Defining only the environmental impact misreads the question.
