CS37: Ethical, Legal & Environmental Impacts
The ethical, legal, environmental, and cultural impacts of technology on society, including legislation, sustainability, and the digital divide.
📋 Overview of Impacts
Key Concept: Technology has wide-ranging impacts beyond just technical considerations. As computing professionals and informed citizens, we need to understand the ethical, legal, environmental, and cultural effects of technology on individuals and society.
| Impact Type | Key Questions |
|---|---|
| Ethical | Is it right? Should we do it? Who is affected? |
| Legal | What laws apply? Is it legal? Who owns the data? |
| Environmental | What is the environmental cost? How much energy? What waste? |
| Cultural | Who has access? Who is excluded? How does it change society? |
🤔 Ethical Impacts
Privacy vs Security
The Debate: Should governments and organisations be able to collect and monitor personal data to improve security? This creates a conflict between individual privacy and collective security.
- Mass surveillance can help prevent terrorism and crime
- But it invades personal privacy and can be misused
- CCTV, data tracking, and monitoring raise privacy concerns
- Where do we draw the line between safety and freedom?
- Different countries have different views on acceptable surveillance
Example
The UK has one of the highest numbers of CCTV cameras per capita in the world. Supporters argue it reduces crime and helps solve cases. Critics argue it creates a surveillance state where citizens are constantly watched, eroding the right to privacy.
Automation and Jobs
The Issue: As technology advances, many jobs are being automated (performed by machines or software instead of people). This raises ethical questions about unemployment, retraining, and economic inequality.
- Manufacturing robots replace factory workers
- Self-service checkouts replace shop workers
- AI and algorithms replace professional tasks (legal research, medical diagnosis)
- Some jobs are created (tech roles) but often require different skills
- Workers displaced by automation may struggle to retrain
Example
Self-driving vehicles could eliminate millions of driving jobs (taxi drivers, lorry drivers, delivery drivers). While the technology may be safer and more efficient, the displaced workers face unemployment and need retraining. The ethical question: should we prioritise efficiency or protect people's livelihoods?
Bias in AI and Algorithms
The Issue: AI systems can reflect and amplify human biases. If training data contains biases, the AI will produce biased results, potentially discriminating against certain groups.
- AI hiring tools may favour certain demographics over others
- Facial recognition has been shown to be less accurate for people of colour
- Criminal risk assessment algorithms may be biased against minorities
- Algorithms may reinforce stereotypes and existing inequalities
- The data used to train AI often reflects historical societal biases
Example
An AI hiring system trained on historical hiring data from a company that historically hired mostly men may learn to favour male candidates, even if the company now wants to hire more diversely. The AI reproduces the bias in its training data.
⚖️ Legal Impacts
Data Protection Act (2018) / UK GDPR
Purpose: The Data Protection Act (DPA) 2018 and the UK GDPR protect individuals' personal data. They give people rights over their own data and impose obligations on organisations that process it.
- Personal data: Any data that can identify a living individual (name, email, photo, IP address)
- Data subject: The person whose data is being processed
- Data controller: The organisation that decides how and why data is processed
- Data processor: The organisation that processes data on behalf of the controller
Key Principles:
- Data must be processed lawfully, fairly, and transparently
- Data must be collected for a specific, explicit purpose
- Data must be adequate, relevant, and not excessive
- Data must be accurate and kept up to date
- Data must not be kept longer than necessary
- Data must be kept secure
Individuals' Rights:
- Right to access their personal data
- Right to have inaccurate data corrected
- Right to have data deleted ("right to be forgotten")
- Right to restrict how data is processed
- Right to data portability
- Right to object to processing
Computer Misuse Act (1990)
Purpose: The Computer Misuse Act makes certain activities involving computers illegal. It was created to address hacking and unauthorised access to computer systems.
| Offence | Description | Example |
|---|---|---|
| Section 1: Unauthorised access | Accessing a computer system without permission | Guessing someone's password to log into their account |
| Section 2: Unauthorised access with intent | Accessing a system without permission to commit a further crime | Hacking into a bank system to steal money |
| Section 3: Unauthorised modification | Modifying computer material without permission | Deploying malware that changes or deletes data |
Copyright, Designs and Patents Act (1988)
Purpose: The CDPA protects the intellectual property of creators. It gives copyright holders the exclusive right to copy, distribute, and adapt their work. It applies to software, music, films, images, and text.
- Copyright automatically applies when a work is created (no registration needed)
- Software is protected as a literary work
- It is illegal to copy, distribute, or modify copyrighted software without permission
- Piracy (illegal copying and distribution) is a criminal offence
- Penalties include fines and imprisonment
Creative Commons
Definition: Creative Commons (CC) is a licensing system that allows creators to share their work legally while specifying how it can be used. It provides standardised licences that sit alongside copyright.
- CC0: No rights reserved - anyone can use for any purpose
- CC BY: Must give credit to the creator
- CC BY-SA: Must give credit and share derivatives under the same licence
- CC BY-NC: Must give credit; non-commercial use only
- CC BY-ND: Must give credit; no derivatives (no modifications allowed)
- Allows legal sharing and reuse without needing to contact the creator
Example
A photographer publishes their photo under CC BY-NC. This means anyone can use the photo for free, as long as they credit the photographer and do not use it commercially. A charity could use it on their website; a company selling products could not.
🌱 Environmental Impacts
E-Waste
Definition: E-waste (electronic waste) is discarded electrical and electronic equipment. It is one of the fastest-growing waste streams globally and contains hazardous materials that can pollute the environment.
- Millions of tonnes of e-waste are generated each year
- Contains toxic materials: lead, mercury, cadmium, arsenic
- If not properly recycled, these toxins leach into soil and water
- Much e-waste is shipped to developing countries for "recycling" but is often dumped
- Workers (including children) in developing countries dismantle e-waste without protection
- Planned obsolescence: devices designed to become outdated quickly, increasing waste
Example
Over 50 million tonnes of e-waste are produced globally each year. Only about 20% is formally recycled. The rest ends up in landfill or is exported to developing countries, where informal recycling causes severe health problems for workers and environmental contamination.
Energy Consumption of Data Centres
The Issue: Data centres - the vast server farms that power cloud computing, streaming, social media, and the internet - consume enormous amounts of electricity for both computing and cooling.
- Data centres consume about 1% of global electricity
- Streaming video, cloud storage, and AI all require massive computing power
- Servers generate heat and need constant cooling (more electricity)
- Many data centres use non-renewable energy sources
- The carbon footprint of the IT industry is comparable to the airline industry
- Training a single AI model can emit as much CO2 as five cars in their lifetime
Carbon Footprint of Technology
- Manufacturing devices requires mining rare earth metals and energy-intensive production
- Using devices consumes electricity (often from non-renewable sources)
- Disposing of devices creates e-waste
- The entire lifecycle of a device has environmental impact
Reducing Environmental Impact:
Extend device lifespan (upgrade, don't replace)
Recycle e-waste properly through certified schemes
Choose energy-efficient devices and data centres
Use renewable energy for data centres
Design software to be computationally efficient
Support right-to-repair legislation

🌍 Cultural Impacts
The Digital Divide
Definition: The digital divide is the gap between those who have access to modern information and communication technology and those who do not. This gap exists both between and within countries.
- Global divide: Developed countries have widespread internet and technology; developing countries may lack infrastructure
- National divide: Urban areas have better connectivity than rural areas
- Socioeconomic divide: Wealthier people can afford devices and broadband; poorer people may not
- Age divide: Younger people are typically more digitally literate than older people
- Disability divide: People with disabilities may find technology inaccessible
Impact of the Digital Divide
During COVID-19 lockdowns, students without home internet or devices could not access online lessons, falling behind their connected peers. This widened the educational gap between wealthy and disadvantaged students. Similarly, people without internet access cannot use online banking, government services, or job opportunities that are increasingly digital-only.
Access to Technology
- Technology can empower people but only if they have access
- Free public Wi-Fi and library computers help bridge the gap
- Cheaper devices (smartphones instead of laptops) improve access
- Digital literacy training is as important as access to devices
- Some governments and organisations are working to close the divide
How Technology Changes Culture
- Social media changes how people communicate and form communities
- Global communication can spread ideas and culture across borders
- But it can also lead to cultural homogenisation (all cultures becoming the same)
- Local languages and traditions may be diminished by dominant online cultures
- Technology can both preserve culture (digital archives) and threaten it

❓ Practice Questions
Q1: Explain the ethical concerns around AI bias. Give an example.
Q2: What is the purpose of the Data Protection Act 2018? State three rights it gives to individuals.
Q3: Describe the three main offences under the Computer Misuse Act 1990.
Q4: What is e-waste and why is it an environmental concern?
Q5: What is the digital divide? Explain how it can affect people's opportunities.
✅ Answers
- AI systems can reflect and amplify biases present in their training data. If historical data contains biases (e.g. favouring certain demographics in hiring), the AI will produce biased results. Example: a facial recognition system trained mostly on lighter-skinned faces was found to be significantly less accurate at identifying darker-skinned faces, leading to potential misidentification.
- The DPA 2018 protects individuals' personal data by setting rules for how organisations collect, store, and process it. Three rights: right to access their personal data, right to have inaccurate data corrected, right to have data deleted (right to be forgotten).
- Section 1: Unauthorised access to a computer system (hacking). Section 2: Unauthorised access with intent to commit a further crime (e.g. hacking to steal money). Section 3: Unauthorised modification of computer material (e.g. deploying malware that changes or deletes data).
- E-waste is discarded electronic equipment (computers, phones, TVs). It is an environmental concern because it contains toxic materials (lead, mercury, cadmium) that can leach into soil and water if not properly recycled. Much e-waste is shipped to developing countries where informal recycling causes health problems and environmental contamination.
- The digital divide is the gap between people who have access to technology and the internet and those who do not. It affects opportunities because those without access cannot use online education, banking, job searching, or government services. During COVID-19 lockdowns, students without home internet fell behind. The divide exists between countries, between urban and rural areas, and between socioeconomic groups.
🎯 Exam Tips
- Know the three key pieces of legislation: DPA 2018, Computer Misuse Act 1990, CDPA 1988
- Be specific about what each law does and the offences/rights it covers
- Creative Commons is NOT the same as "no copyright" - it is a type of licence
- For ethical questions, present balanced arguments (e.g. privacy vs security)
- Environmental: mention e-waste AND energy consumption of data centres
- Cultural: the digital divide affects education, employment, and social inclusion
- Always name specific legislation rather than saying "the law says"
⚠️ Common Errors
✗ Confusing the Data Protection Act and the Computer Misuse Act ✓ The DPA (now UK GDPR) protects personal data about individuals. The Computer Misuse Act criminalises unauthorised access to computer systems (hacking). They protect different things.
✗ Thinking copyright only applies to music and films ✓ Copyright applies to any original creative work: software, code, databases, images, text, designs. Copying software without a licence is a copyright violation.
✗ Believing technology always has a negative environmental impact ✓ Technology has both negative impacts (e-waste, energy consumption of data centres) and positive impacts (remote working reduces travel, smart grids reduce energy waste, digital documents reduce paper use).
✗ Not understanding the difference between AI bias and algorithmic bias ✓ AI bias occurs when training data under-represents certain groups, leading to unfair outcomes. Algorithmic bias occurs when the logic of an algorithm systematically favours one group over another, regardless of training data.
✍️ Model Answer
Full-Mark Response
Discuss the ethical, legal, and environmental impacts of self-driving cars. Include at least one point for each category and reference relevant legislation. [6 marks]
Ethical impacts: Self-driving cars face ethical dilemmas in accident scenarios — e.g. should the car prioritise passenger safety or minimise pedestrian casualties? This 'trolley problem' requires programming moral decisions into algorithms. There is also concern about AI bias if training data under-represents certain road conditions or demographics. Legal impacts: If a self-driving car causes an accident, determining liability is complex — is the manufacturer, the software developer, or the vehicle owner responsible? The Autonomous Vehicles Act 2024 addresses some of these issues. Data collected by sensors raises DPA/UK GDPR concerns about personal data (e.g. facial recognition of pedestrians). Hackers targeting car systems could fall under the Computer Misuse Act. Environmental impacts: Self-driving cars can optimise routes and driving patterns, reducing fuel consumption and emissions through smoother acceleration and braking. However, manufacturing batteries and sensors creates environmental costs, and increased car use (due to convenience) may offset efficiency gains. The disposal of electronic components contributes to e-waste challenges.
