Sustainable development is an HL-only challenge topic about how digital systems interact with environmental needs, resource use, and pollution. Students investigate both the opportunities digital systems create and the environmental problems they may cause, then evaluate possible interventions.
A challenge in IB Digital Society is a widespread, persistent issue with far-reaching impacts and implications for people and communities. Sustainable development is therefore not simply about learning environmental facts. It requires examining how digital systems, including data centres, artificial intelligence, sensors, networks, and electronic devices, affect environmental sustainability.
The topic contains three prescribed areas for inquiry:
| Area for inquiry | Main focus |
|---|---|
| Climate change and action | How digital systems contribute to emissions, measure environmental change, or support climate action. |
| Use of resources | How digital systems consume energy, water, minerals, and other resources, and how they may improve efficiency. |
| Managing pollution and waste | How digital systems create problems such as electronic waste, or help monitor, prevent, and reduce pollution. |
Students must also investigate interventions, meaning innovations involving digital systems that attempt to mitigate, intercede in, enhance, or resolve part of a challenge. An intervention could be a digital monitoring system, a repair and recycling platform, or a policy governing electronic waste.
The key reasoning is based on trade-offs. For example, an AI system might help optimize electricity distribution, but operating its data infrastructure may consume substantial energy and water. The impact is an effect that has already occurred, while the implication is a future opportunity or risk.
A common misconception is that sustainable development means only reducing environmental harm. In Digital Society, it also involves competing stakeholder interests, unequal access to resources, costs, feasibility, ethics, and long-term consequences.
For HL exams, connect this topic to Paper 1 Section B and Paper 3. Examiners expect balanced evaluation of specific interventions and well-supported recommendations that consider criteria such as equity, cost, feasibility, acceptability, innovation, and ethics.
