Permacomputing: Tackling the Problem of Technological Waste
Towards degrowth computation, with ICT planned for longevity not obsolescence.
From analyzing environmental data to powering cleaner technologies, computers undeniably have a significant role to play in tackling the climate crises. Yet, while increasing computational power has long been cited as a driving force for improving efficiency and reducing emissions, in reality, things are not quite that simple. Instead, the demand for computing technology has resulted in a paradox: the technologies supposed to empower us are leading to significant waste, insatiable consumer demand, and increased pollution.
A study by Lancaster University suggests that ICT currently accounts for around 2.1–3.9% of global emissions. And crucially, these emissions (despite the increased efficiency of computers) are growing. If we assume continued relative growth, ICT’s relative contribution will exceed 14% of the 2016-level worldwide GHGE by 2040. In other words, around 10 GtCO₂e, or about 80% of the acceptable CO₂ emissions budget.
In response, tech optimists often argue that innovation will save us from disaster. However, even a near-future utopia of super-efficient computation does not solve the problem. That is because, as computer science professor Wim…
