The carbon footprint difference between manufacturing new electronics and refurbishing existing ones is substantial. For organisations looking to reduce their environmental impact, understanding this gap helps justify investment in refurbishment programmes and circular IT procurement. The numbers make a compelling case that extending the life of existing equipment is one of the most effective carbon reduction strategies available to any business.
The Carbon Cost of Manufacturing New Electronics
Manufacturing electronic devices is one of the most carbon-intensive production processes per unit weight. The lifecycle emissions of new IT equipment come from several stages.
Raw material extraction accounts for a significant portion. Mining and processing the dozens of different metals, minerals, and materials that go into a single electronic device generates emissions from diesel-powered mining equipment, energy-intensive ore processing, chemical refining of metals, and transportation of raw materials to component factories. The materials in a single smartphone include over 60 different elements, each with its own extraction and processing footprint.
Component manufacturing is the largest single contributor to embodied carbon. Semiconductor fabrication, the process of creating the processors and memory chips at the heart of all electronics, is extraordinarily energy intensive. A modern semiconductor fabrication facility consumes as much electricity as a small city. Battery production, display manufacturing, and circuit board assembly all add to the total.
Assembly brings components together into finished products. While less energy intensive than component manufacturing, assembly still contributes through factory energy use, quality testing, and localised transportation.
Packaging and distribution add the final emissions layer, including materials for packaging, warehousing energy, and transportation from assembly plants (predominantly in Asia) to end markets like Australia.
Typical Manufacturing Carbon Footprints
Based on lifecycle assessments and manufacturer environmental reports, typical embodied carbon figures for new equipment include laptops at 300 to 400 kg CO2e, desktop computers at 300 to 500 kg CO2e, monitors (24 inch) at 200 to 350 kg CO2e, smartphones at 50 to 80 kg CO2e, tablets at 80 to 120 kg CO2e, servers (rack-mounted) at 1,000 to 4,000 kg CO2e, and network switches (enterprise) at 200 to 800 kg CO2e.
These figures represent the carbon debt incurred before the device is even switched on for the first time.
The Carbon Cost of Refurbishment
Refurbishing an existing device generates a fraction of the emissions associated with manufacturing a new one. The refurbishment process typically involves data destruction (software-based wiping or physical drive replacement), functional testing and diagnostics, component replacement where needed (batteries, hard drives, keyboards), cleaning and cosmetic restoration, repackaging, and quality assurance testing.
The total carbon footprint of refurbishment is typically 10 to 30 kg CO2e for a laptop, depending on the extent of work required and the transportation involved. This means refurbishment generates roughly 5 to 10 percent of the carbon footprint of manufacturing a new device.
The biggest variable in refurbishment carbon is transportation. If equipment needs to be shipped internationally for refurbishment, the transport emissions can be significant. Domestic refurbishment within Australia minimises this variable.
The Carbon Savings Calculation
The carbon savings from choosing refurbished over new is straightforward. Take the embodied carbon of a new device, subtract the refurbishment carbon, and the difference is your avoidance. For a typical business laptop, the calculation is approximately 350 kg (new manufacturing) minus 20 kg (refurbishment) equals 330 kg CO2e avoided per unit.
At organisational scale, these savings multiply rapidly. An organisation that purchases 100 refurbished laptops instead of new ones avoids approximately 33 tonnes of CO2e, equivalent to taking about 14 cars off the road for a year.
Materials Recovery Through Recycling
When equipment is too old or damaged for refurbishment, recycling is the next best option. While recycling generates more emissions than refurbishment, it still produces significant carbon savings compared to manufacturing from virgin materials. Recycling aluminium uses about 95 percent less energy than producing it from bauxite ore. Recycling copper saves approximately 85 percent of the energy compared to primary production. Recycling steel saves around 70 percent of the energy compared to producing from iron ore. And recovering precious metals like gold and palladium from circuit boards avoids the enormous energy and environmental cost of mining.
The materials recovered through e-waste recycling re-enter manufacturing supply chains, reducing the need for energy-intensive primary extraction and processing.
Procurement Implications
Understanding the carbon gap between new and refurbished electronics has direct procurement implications. Organisations can reduce their Scope 3 emissions by purchasing refurbished equipment where it meets operational requirements, extending the lifecycle of existing equipment through maintenance and upgrades, choosing manufacturers with lower embodied carbon (some manufacturers are investing in renewable energy for their factories), and ensuring retired equipment enters refurbishment pathways rather than going straight to recycling.
Including embodied carbon as a factor in IT procurement decisions, alongside price, performance, and support, drives market demand for lower-carbon products and circular economy practices.
Reporting the Comparison
When reporting the carbon benefits of your refurbishment and circular IT practices, clearly state the emission factors used for both new manufacturing and refurbishment, cite the sources of your lifecycle assessment data, acknowledge any uncertainty in the figures, and present the savings in context that stakeholders can relate to.
