Berners-Lee, the author of There Is No Planet B and this year's A Climate of Truth(2025), blends hard numbers with blunt honesty: What happens when AI’s rising energy appetite collides with net-zero targets—and how do we turn the technology into a force for “net good”? Drawing on two decades of carbon-accounting research at Small World Consulting and policy work with governments and Big Tech, Berners-Lee will unpack the true climate cost of our digital future and outline the policy levers, pricing tools, and behavioural shifts that can still tip the balance. Come ready for uncomfortable facts—and practical ways to act on them.
