What is e-waste and why does its carbon footprint matter?
E-waste — or waste electrical and electronic equipment (WEEE) — refers to any device with a plug, battery, or electrical component that has been discarded. It includes laptops, desktops, smartphones, tablets, monitors, printers, and networking equipment, as well as household appliances.
The WEEE Forum, which coordinates e-waste data internationally, estimated in its 2023 report that 62 million tonnes of e-waste were generated globally in 2022. The UK is among the highest per-capita generators of e-waste in the world, according to figures from the Global E-waste Monitor.
What makes e-waste particularly significant from a carbon perspective is not simply that devices end up in waste streams — it is the emissions baked in long before a device ever reaches a consumer, and the additional emissions released when it is disposed of incorrectly.
What is embodied carbon in electronics?
Embodied carbon refers to the greenhouse gas emissions associated with manufacturing a product — from raw material extraction through component production to final assembly. It stands in contrast to operational carbon, which is the emissions produced during use.
For electronics, embodied carbon is disproportionately high relative to operational carbon. This is because:
- Mining and refining the metals inside a device (copper, aluminium, cobalt, lithium, rare earth elements) is extremely energy-intensive
- Semiconductor fabrication — producing the chips inside every device — requires vast quantities of ultra-pure water, chemicals, and energy
- Global supply chains mean materials and components are transported multiple times before final assembly
Studies have suggested that for a typical laptop, manufacturing accounts for up to 80% of its total lifetime carbon footprint — more than all the electricity it will ever consume. (Source: Apple Environmental Progress Reports and independent lifecycle assessments; specific figures vary by manufacturer and model.) The implication is significant: the moment a working device is discarded and replaced by a new one, a large carbon debt is created.
How does improper e-waste disposal add to the carbon footprint?
When devices reach end of life and are not processed responsibly, additional carbon impacts occur.
Landfill leakage: electronic components contain materials — including certain flame retardants and refrigerants in older devices — that can release greenhouse gases as they degrade. Landfill is the worst possible outcome for electronics, both from a carbon and a toxicity perspective.
Informal recycling: a significant proportion of global e-waste is exported to informal recycling operations, primarily in West Africa and South-East Asia. Informal processing often involves open burning of cables to recover copper, releasing carbon dioxide, carbon monoxide, and other pollutants. This is both a carbon problem and a serious public health issue.
Lost materials: when valuable materials are not recovered — or are recovered at low efficiency — new mining must take place to replace them. Each tonne of virgin copper or aluminium extracted has a carbon cost that could have been avoided by recovering and recycling existing material.
Wasted embodied carbon: every device that is discarded prematurely wastes the embodied carbon already spent on its manufacture. If a device could have provided three more years of service but is retired after one, two-thirds of that embodied carbon investment is effectively written off.
What contribution does the UK’s e-waste make?
The UK generates a substantial volume of e-waste annually. According to the Environment Agency and WEEE compliance scheme data, the UK formally collected over 600,000 tonnes of WEEE for treatment in 2022 (Environment Agency WEEE data tables, gov.uk). However, collection rates for certain categories — including small IT and telecommunications equipment — remain well below the levels required to meet circular economy targets.
A significant portion of discarded IT equipment either enters general waste streams — where it is not separately processed — or is handled by uncertified operators who may not meet the standards required under the WEEE Regulations 2013.
For businesses, this creates both a compliance risk and a carbon reporting gap. If IT equipment disposed of through general waste channels has not been tracked, the carbon impact of that disposal cannot be accurately reported — including for Scope 3 emissions disclosures under GHG Protocol frameworks.
How does responsible ITAD reduce the e-waste carbon footprint?
Certified IT asset disposal (ITAD) addresses the e-waste carbon footprint at two levels.
Avoiding new manufacturing is the higher-impact intervention. When a device is refurbished and reused rather than discarded, it displaces the need for a new device. The new device that is not manufactured represents a substantial carbon saving — equivalent to the embodied carbon that would have been created. This is why reuse is more valuable than recycling in carbon terms.
Maximising material recovery is the second-level benefit. When recycling is necessary, certified WEEE processors recover metals at high efficiency using controlled processes. This reduces the volume of virgin material that must be mined and refined to meet demand.
At Recycle4Charity, our priority is always reuse. Devices collected from London businesses are assessed, refurbished where possible, and donated to digitally excluded Londoners. Only when refurbishment is not viable are devices recycled through our certified partners. This hierarchy — reuse first, then recycle — maximises the carbon benefit at every stage.
To understand the full environmental case for IT reuse, visit our impact page or read about how reusing IT equipment cuts carbon emissions.
Every device you send to Recycle4Charity avoids landfill, achieves secure data destruction, and — wherever possible — finds a new home rather than being reduced to scrap. Book a collection today.
