Even though we still need more work and more evidence, the digital world has a strong influence on the environment (and vice versa). The environmental footprint of the digital world is estimated to virtually amount to a 7th continent (or up to 5.6% of humanity’s global footprint). At the same time, digital technologies can be of paramount importance in effectively tackling environmental issues. Operations related to information and communications technologies (ICT) are expected to represent up to 20 percent of global electricity demand, with one third stemming from data centres alone.
