According to the study, 1.8 to 3.2 percent of global greenhouse gas emissions are attributable to the manufacture and operation of digital devices and infrastructures. Data centers and communication networks each account for around 15 percent, and hardware and end devices for around 70 percent. Overall, the study authors consider a magnitude of around 900 to 1,100 megatons of CO2 equivalent in 2020 for global greenhouse gas emissions from hardware in the ICT sector and in consumer electronics to be plausible. According to this calculation, data centers and networks each account for around 200 to 250 megatons of CO2 equivalent in 2020. Whether emissions will continue to increase in the future due to growing digital hong kong gambling data infrastructures and the increasing number of digital devices in private households and companies depends largely on the energy mix in the national power grids.
Global potential: Digital technologies can save up to 20 percent of global greenhouse gas emissions - but the scientific scenarios on this differ. The greatest climate potential of digitalization lies in the energy (electricity and heat), buildings, and mobility and transport sectors. Greenhouse gas emissions can also be massively reduced in agriculture and industry through consistent digitalization.
Potential in Germany: With the help of digital technologies and solutions, emissions of up to 290 megatons of CO2 equivalent can be avoided in Germany in 2030 - this would correspond to around 37 percent of the predicted greenhouse gas emissions for 2030. The potential in Germany is almost twice as large as the global average and lies primarily in industrial production and the building sector, followed by the transport and energy sectors.
