In the report, "Impacts and Insights, Circular IT Management in Practice," TCO Development investigates the GHG output from the manufacturing, distribution, use and disposal of a notebook computer and how purchasing a new one affects GHG emissions, compared with extending the life of an existing device.
The analysis concludes that a vast majority of the GHGs are emitted in the manufacturing phase. When a notebook is used for four years, the estimated total carbon footprint is 299 kilograms during its life cycle. Of this, 79.8 percent of the greenhouse gases are emitted in the manufacturing phase, 6.8 percent during transportation, 13.2 percent in the use phase and 0.2 percent at end of life.
Because almost 80 percent of emissions occur in the manufacturing phase, extending a notebook computer’s product life clearly will lead to substantial reductions of GHG emissions.
When a notebook is used for six years instead of four, GHG emissions are reduced by 29 percent. For an organization with 1,000 employees, this means a reduction of 216,250 kg over a 10-year period. This strategy also saves natural resources and prevents electronic waste.
