The lifetime “embodied” carbon of data centre IT assets, such as servers, storage and network equipment, can be over a tonne. Dell considers theirs to be in the region of 1250kg – 1750kgs of CO2e, and up to 90% of this is in the PCB manufacture. That’s the amount already consumed before they even get installed - let alone power up - and accounts for the sourcing of raw materials, component assembly, manufacturing, and transportation implications.
