The report ‘Carbon impact of video streaming’ states that carbon emissions of the ICT sector increased over the period from the early 1990s to 2010. However, this emissions trend has plateaued, remaining relatively stable over the last decade, despite network data volumes continuing to grow year on year. The ICT emissions curve has flattened and actually dropped from 1.5 per cent to 1.3 per cent of global carbon emissions over the past decade, while the absolute emissions of ICTs have fallen slightly from a peak of 730 MtCO2e in 2015 to 710 MtCO2e in 2018, and to about 690 MtCO2e in 2020. The volume of e-waste is on the rise however, from 44.7 Megatons generated in 2016 to 53.6 Megatons in 2019, while the percentage of this e-waste (which is documented for collection and properly re-cycled) decreased from 20 per cent to 17.4 per cent in the same period. Cyberthreats are also on the rise. However, the percentage of countries having established a CIRT, CERT or CSIRT increased from 56 per cent in 2019 to 60.82 in 2020.
