Read Disrupting the climate by Duncan McCann (

Digital technology has an impact on climate change in three distinct ways – all of which we need to radically change if we want a chance of preventing climate chaos.

Digital technology’s effect on the environment.

It uses a lot of raw materials; produces a lot of CO2 in manufacture; and the ‘cloud’ uses a vast amount of energy in use.

“What we really need is a whole new way of thinking about digital technology. In a world focused on ownership driven by conspicuous consumption, in the thralls of a digital revolution, we have created a sprawling global beast that might consume our society as well as ever greater amounts of energy and resources.”

Things we should do: use materials more efficiently; make things more repairable; use renewable energy.

I’d probably also add ‘abolish capitalism’ to the list.
