Our Global IT System, climate destroyer?
summary
Claims that IT saves energy are false: the global digital system is a greenhouse‑gas enabler, not a reducer. The full footprint — manufacturing plus electricity to run networks, data centers and devices — equals about 4% of global CO2, rising ~10% per year, split roughly half manufacturing, half operation. The talk uses energy accounting, lifecycle material lists and historical energy graphs to argue decoupling is impossible at current GDP levels and that keeping hardware small and long‑lived is the only practical mitigation.
