What this dot point is asking
This is Edexcel key idea 1.2. Edexcel wants you to recognise the importance of an evaluative process when judging new and emerging technologies, and to apply it to real and future scenarios from ethical and environmental perspectives. The named content is the criteria for critically evaluating technologies (1.2.1), how evaluations inform decisions in contemporary and future scenarios (1.2.2), ethical perspectives (1.2.3) and environmental perspectives (1.2.4). In Section A this appears as Explain and extended-open-response questions, often built around a product context.
Why critically evaluate a technology
A new technology is not automatically the right choice. Evaluating it against clear criteria prevents costly mistakes and unsustainable decisions.
These same criteria help inform decisions in contemporary and potential future scenarios (1.2.2): natural disasters (rapid shelter or water purification), medical advances (prosthetics, 3D-printed implants), travel (electric and autonomous vehicles), global warming (low-carbon and renewable products) and communication (connected devices). The designer asks how a technology performs in each scenario before adopting it.
Ethical perspectives
Edexcel's ethical questions (1.2.3) are where it was made, who it was made by, who will benefit and whether it is a fair trade product. A technology might cut costs by using cheap overseas labour, but an ethical evaluation weighs the impact on those workers, on local communities, and on the company's reputation with consumers who care about fairness.
Environmental perspectives and life cycle analysis
A carbon footprint is the total greenhouse gas emitted across a product's life, measured as carbon dioxide equivalent. An LCA breaks the life into stages and totals the impact at each, so two designs or materials can be compared fairly. This lets a designer choose the option with the lower overall footprint, not simply the cheapest, and identify the worst stage to improve (often material extraction or transport).
Exam-style practice questions
Practice questions written in the style of Pearson Edexcel exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Edexcel 20226 marksA company is choosing a material for a new range of children's toys. Explain how a life cycle analysis (LCA) could inform this design decision. (6 marks)Show worked answer →
A 6-mark Explain is marked by levels. Markers reward an answer that shows what an LCA examines and links each stage to the toy design decision.
A life cycle analysis assesses the environmental impact of a product across its whole life, in stages: raw material extraction, processing and manufacture, transportation and distribution, use, and disposal or recycling. For the toys, an LCA would compare materials (for example a recycled polymer against virgin ABS) at each stage.
It could show that one material uses less energy and water to extract and process, travels a shorter distance, lasts longer in use (so fewer replacements), and can be recycled at end of life rather than going to landfill. The company can then choose the material with the lower overall footprint, not just the lowest purchase price.
A Level 3 answer names the LCA stages, applies them to the toy, and concludes that the LCA lets the company make an evidence-based, sustainable choice. Markers reward the stages and the applied link.
Edexcel 20214 marksExplain how ethical considerations might influence the choice of supplier for a new fashion product. (4 marks)Show worked answer →
A 4-mark Explain rewards two developed points about ethics and supply.
Point 1: choosing a fair trade or certified supplier ensures workers are paid a fair wage and work in safe conditions (1), which avoids exploitation and protects the company's reputation with ethically minded consumers (1).
Point 2: considering where and by whom a product is made lets the company avoid suppliers using child labour or unsafe factories (1), reducing the risk of harm and of negative publicity that would damage sales (1).
Markers reward the ethical factor (fair trade, fair wages, safe conditions, no child labour) and its consequence for people or the business. Naming "fair trade" without explaining its effect earns 1 mark.
