Life cycle emissions of a computer
“Manufacturing computers is materials-intensive; the total fossil fuels used to make one desktop computer weigh over 240 kilograms, some ten times the weight of the computer itself. This is very high compared to many other goods: For an automobile or refrigerator, for example, the weight of fossil fuels used for production is roughly equal to their weights. Substantial quantities of chemicals (22 kg), and water (1 500 kg) are also used.” Eric Williams, Computers and the Environment. Understanding and managing their impact, 2004.
