Environmental, Ethical and Legal Issues
Why Technology Has Consequences
Every device you use, every app you run, and every file you upload has costs and consequences beyond its obvious function. These fall into three categories: environmental issues, ethical issues, and legal issues. Understanding all three helps you evaluate technology honestly — not just what it can do, but what it costs and what rules govern its use.
Environmental Impact: Manufacture
A digital device does not start its environmental life when you switch it on — it starts when its materials are extracted from the ground. Producing a smartphone, laptop or server requires mining rare earth minerals and metals such as lithium, cobalt, copper and gold. These mining operations can cause habitat destruction, water pollution and significant carbon emissions. The energy-intensive fabrication processes used to manufacture processors and circuit boards add further to the carbon cost. Every new device purchased represents environmental impact before the device is even used.
Environmental Impact: Energy Consumption in Use
Running digital devices and the infrastructure that supports them requires vast amounts of electricity. Data centres power the internet, cloud services and streaming platforms. They run continuously and require cooling systems — which themselves consume electricity and water — to prevent equipment from overheating. Individual devices (phones, laptops, televisions) consume energy throughout their lifetimes, and wireless network infrastructure (mobile masts, routers) requires continuous power to operate.
The four stages of a device’s environmental impact are: manufacture (mining, fabrication emissions), energy consumption in use (data centres, devices, networks), replacement cycle (how often devices are upgraded), and disposal (e-waste and toxic materials).
Environmental Impact: Replacement Cycle and Disposal
The rate at which consumers replace devices matters. When manufacturers design products to become outdated or to stop receiving software updates after a few years — a practice sometimes called planned obsolescence — they accelerate the replacement cycle. Each discarded device becomes e-waste (electronic waste). Devices contain hazardous substances including lead, mercury and cadmium. When sent to landfill, these substances can leach into soil and groundwater. Informal recycling in some regions exposes workers to toxic chemicals. Responsible disposal requires using official recycling or manufacturer take-back schemes.
Individuals can help by repairing rather than replacing devices, choosing refurbished hardware, and using official recycling and take-back schemes. Manufacturers can design products that are easier to repair, use more recycled materials, and provide software support for longer. Organisations can choose data centre providers that run on renewable energy or use waste-heat recovery. Technology can also reduce other environmental harms: remote working cuts commuting emissions, digital documents replace paper, and smart energy systems can optimise heating and lighting in buildings.
Ethical Issues: Privacy and Personal Data
Privacy is the central ethical concern of the digital age. Every time you use a smartphone, banking app or social media platform, data about you is collected — your location, browsing history, financial transactions and social connections. Most people value the ability to control what others know about them. Privacy is challenged when organisations collect data that goes beyond what is necessary, share it without consent, or use it in ways users did not expect.
Three key ethical questions arise around personal data:
- Ownership — who owns the data generated by your activity online? In many cases, the platform that collects it claims ownership, even when it relates entirely to your behaviour and preferences.
- Consent — have users genuinely agreed to their data being collected and used in specific ways? Long, complex privacy policies can obscure the scope of what users are agreeing to.
- Misuse — data collected for one purpose (for example, measuring fitness activity) could be shared with insurers or employers and used to make decisions that affect a person’s life without their knowledge.
Three ethical dimensions of personal data: ownership (who holds rights over data you generate?), consent (have users genuinely agreed to how data is used?), misuse (can data collected for one purpose be used in ways that harm the person?). All three are addressed by the Data Protection Act 2018.
UK Data Protection Law
The Data Protection Act 2018 governs how organisations handle personal data. It incorporates the requirements of UK GDPR (the UK’s retained version of European data protection regulation). Under the Act, organisations must: collect data only for a specific, stated purpose; keep it secure; not hold it for longer than necessary; and give individuals the right to access, correct or request deletion of their own data. Failure to comply can result in significant fines from the Information Commissioner’s Office. The Act replaced the earlier Data Protection Act 1998.
Intellectual Property: Copyright, Patents, Trademarks and Licencing
When someone creates software, music, a logo or an invention, they have rights over that creation. Intellectual property law protects those rights. There are four types you need to know.
Copyright — protected in the UK by the Copyright, Designs and Patents Act 1988. Creative works — including software, music, images, films and written content — are automatically protected from the moment of creation. Copying or distributing copyrighted material without permission is illegal, even for personal rather than commercial use.
Patents — a patent gives an inventor the exclusive right to make, use or sell an invention for a limited period (typically 20 years in the UK). In return, the inventor publishes how the invention works. Patents can protect hardware designs and algorithms in some circumstances, but pure software ideas are generally not patentable in the UK.
Trademarks — a trademark protects a distinctive name, logo or symbol associated with a product or brand. Technology companies register trademarks to prevent competitors from using confusingly similar names or logos. Unlike copyright, trademarks must be formally registered and renewed to maintain protection.
Licencing — a software licence is a legal agreement between the rights holder and a user, setting out what the user may do with the software. A proprietary licence restricts copying, modification and redistribution. An open-source licence (such as the GNU GPL) permits users to view, modify and share the source code, subject to conditions. Using software outside the terms of its licence is a breach of copyright law.
The Computer Misuse Act 1990
The Computer Misuse Act 1990 makes it a criminal offence to access a computer system without authorisation. It covers three categories of offence: gaining unauthorised access to computer material (for example, logging into someone else’s account without their permission); gaining unauthorised access with intent to commit or facilitate a further offence (for example, accessing a network to commit fraud); and making unauthorised modifications to computer material (for example, installing malware or deleting data). A 2015 amendment to the Act increased maximum penalties and extended its coverage to attacks on computer infrastructure. Hackers can face imprisonment and unlimited fines under this legislation.
