Ethical, legal and environmental impacts of digital technology
Digital technology shapes every aspect of modern life — from how we communicate and work to how governments make decisions. With this power comes responsibility. AQA GCSE Computer Science requires students to evaluate the impact of computing across four interconnected dimensions: ethical, legal, environmental and privacy.
Why this section matters
Technology is not neutral. Every design decision embeds values:
- An algorithm trained on biased data perpetuates discrimination
- A law that criminalises unauthorised access shapes how we use computers
- A data centre powered by coal contributes to climate change
- A social media platform that tracks users influences what they see and believe
Computing professionals have an obligation to consider these impacts — not just whether something can be built, but whether it should be.
Ethical issues (CS8.1)
Ethics asks what is right and wrong. In computing:
- AI bias — systems learn from historical data; if that data is biased, outputs are biased. Affects hiring, lending, policing and medical diagnosis.
- Censorship — governments and platforms restrict content. Benefits: removes harmful material. Risks: suppresses free speech.
- Privacy intrusions — technology enables unprecedented surveillance (CCTV, online tracking, smart devices).
- Digital divide — unequal access to technology creates and compounds social inequality.
Legal issues (CS8.2)
Three UK laws govern computing conduct:
| Law | What it covers |
|---|---|
| Data Protection Act 2018 | How personal data must be collected, stored and used |
| Computer Misuse Act 1990 | Unauthorised access to or modification of computer systems |
| Copyright, Designs and Patents Act 1988 | Protecting original creative works including software |
Creative Commons licensing allows creators to share works with specific permissions (BY, SA, NC, ND), providing a legal route between "all rights reserved" and public domain.
Environmental issues (CS8.3)
Digital technology has a significant environmental footprint:
- Data centres consume ~1–2% of world electricity; cooling doubles energy use
- E-waste — 53 million tonnes per year; less than 20% formally recycled; hazardous materials leach into soil
- Manufacturing — rare earth mining, semiconductor fabrication and device production carry large carbon and water footprints
- Planned obsolescence — frequent device replacement drives demand and waste
Mitigations: renewable energy for data centres, right to repair legislation, circular economy design, formal e-waste recycling.
Privacy issues (CS8.4)
Beyond surveillance: how data is used once collected.
- Tracking — cookies, GPS, purchase history, social media activity
- Profiling — combining data to build detailed individual profiles for advertising, credit and political targeting
- Biometric data — cannot be changed if compromised; special category data under DPA 2018
- Right to erasure — individuals can request deletion of their data
- Informed consent — users must actively agree; pre-ticked boxes are invalid
Balancing competing values
Rarely is there a clear right answer. Good exam responses:
- Present multiple perspectives — who benefits? Who is harmed?
- Use precise terminology — name the relevant law, the type of bias, the specific threat
- Reach a reasoned conclusion — don't sit on the fence indefinitely
- Acknowledge trade-offs — more security often means less privacy; more convenience often means less control
The role of computing professionals
The British Computer Society (BCS) Code of Conduct asks professionals to:
- Act in the public interest
- Have professional competence and integrity
- Maintain professional development
- Promote exemplary practice
