Sustainability is one of the most important and frequently tested themes in IB Design Technology. It appears across exams, extended responses, and the design project, yet many students handle it superficially. Simply stating that a product is “sustainable” or “eco-friendly” is not enough to earn marks.
In IB Design Technology, sustainability is about evaluating the long-term impact of design decisions on the environment, society, and resources.
What Sustainability Means in IB Design Technology
Sustainability refers to designing products and systems that:
- Minimise environmental damage
- Use resources responsibly
- Consider long-term consequences rather than short-term convenience
In IB Design Technology, sustainability is not a standalone topic. It is integrated into user-centred design, materials selection, production methods, and evaluation.
Examiners want students to show that they understand trade-offs, not idealised solutions.
Where Sustainability Appears in Exams
Sustainability commonly appears in:
- Scenario-based questions
- Evaluation and extended-response questions
- Ethics and responsibility prompts
Questions often describe a product or design situation and ask students to analyse or evaluate environmental impact. Students who link sustainability directly to the scenario score higher than those who use generic statements.
Common Sustainability Themes in Exam Questions
Materials and Resource Use
Students are often asked to evaluate:
- Renewable vs non-renewable materials
- Durability and lifespan
- Environmental cost of material extraction
