The International Energy Agency held a high-profile roundtable with climate and energy leaders from around the world in Paris on 20 February, including the presidents of the forthcoming Cop29 and Cop30 climate conferences, to discuss the next energy transition steps focusing on large multilateral public and private finance initiatives and new clean technologies, including nuclear power.

US climate change presidential envoy John Kerry said “we will be producing in Massachusetts at the Commonwealth Fusion Plant in three years something like 40 MW of power. Finally coming with a proof of concept for this [fusion].”

“There is no question that we can surprise ourselves with the technologies being worked on,” he added.

“We need to build out storage and transmission capacity,” Kerry said. “There is no faking it in this next period of time, we must do the things that we need to do, the world needs to come together.”
