“Digital Technology and the Environment” or “We Could Have Saved the Bees, We Chose to Release a New iPhone”
summary
The talk presents data showing the digital sector’s rapid ~9% annual growth, with about 5 billion smartphones by 2020 and device manufacturing responsible for roughly 45% of digital energy use (terminals ~60% of total). It highlights that short replacement cycles (80–90 kg CO2 per phone) and video traffic (online video ~300 Mt CO2 in 2018; Netflix comparable to a large cement plant) drive much of the footprint, and it advocates extending device lifetimes, changing user behaviour, and implementing systemic policy limits as levers to reduce impact.
