The environmental impact of transcontinental data traffic
Submarine cables carry over 97 percent of transcontinental voice and data traffic. The high capacity and bandwidth of fibre optic cables make it possible to transfer large amounts of data around the globe almost instantaneously. A new study by Craig Donovan takes a look at the environmental impact of submarine cables from a life cycle perspective. He shows that 7 grams of carbon dioxide equivalents are potentially released for every ten thousand gigabit kilometres (10,000Gb.km).
