What this dot point is asking
CCEA Unit 3 expects you to know what the engineering and manufacturing sector is, its main branches and careers, and to discuss its impact on the economy, society and the environment, including sustainable development. This is an explanation and discussion topic, often an extended-answer question.
The answer
The sector and its branches
Impact on the economy and society
Impact on the environment
The sector also has negative environmental impacts: it uses finite raw materials and energy (resource depletion), and causes pollution and waste through emissions, scrap and end-of-life products in landfill. Manufacturing processes can also use a lot of water and energy.
Sustainable development
Worked example: weighing the impact of a product
Examples in context
- Example 1. A local manufacturer
- Provides skilled jobs and apprenticeships and supplies products to other firms, contributing to the economy and the community.
- Example 2. A factory reducing impact
- Switches to recycled materials, fits efficient machines to cut energy use, and recycles its scrap, lowering both cost and environmental impact.
- Example 3. Designing for end of life
- A product is designed so its parts can be separated and recycled, supporting sustainable development by conserving resources and reducing landfill.
The pattern is that the sector brings major economic and social benefits but carries environmental costs, and sustainable design, recycling and efficiency are how engineers reduce those costs.

Q1. Give one positive impact of the engineering and manufacturing sector on society or the economy. [1 mark]
- Cue. It creates jobs and wealth, or provides useful products that improve everyday life.
Q2. Give one negative impact of manufacturing on the environment. [1 mark]
- Cue. It uses finite raw materials and energy, or causes pollution and waste.
Q3. What does sustainable development mean? [2 marks]
- Cue. Meeting today's needs without harming the ability of future generations to meet their own needs.

CCEA style4 marksDescribe two ways that engineering and manufacturing have a positive impact on society or the economy, and two ways they can have a negative impact on the environment.Show worked answer →
Two positive impacts:
- They create jobs and wealth, supporting the economy and providing skilled careers (and apprenticeships).
- They provide useful products that improve everyday life, such as transport, medical devices, homes and communications.
Two negative environmental impacts:
- They use up finite raw materials and energy (resource depletion).
- They cause pollution and waste (emissions, landfill) during manufacture and at the end of a product's life.
Markers reward two valid positive impacts (jobs, wealth, useful products, innovation) and two valid negative environmental impacts (resource use, pollution, waste, emissions).
CCEA style3 marksExplain what sustainable development means in engineering and give two ways a manufacturer can work more sustainably.Show worked answer →
Sustainable development means meeting today's needs without harming the ability of future generations to meet their own needs, so resources are used responsibly and the environment is protected.
Two ways a manufacturer can be more sustainable:
- Use recycled materials and recycle waste, reducing the demand for new raw materials and landfill.
- Reduce energy use and waste in production (efficient machines, less scrap), and design products to last and be recyclable.
Markers reward the definition (meeting needs now without harming future generations) and two valid sustainable practices (recycling, energy/waste reduction, durable/recyclable design, renewable energy).
