Ireland set itself an ambitious climate target of a 51% emissions reduction by 2030 – aligning with the EU’s climate law objective – and just announced it will only achieve half that. As it heads towards its EU Presidency this July, Ireland faces a concrete opportunity to step up as the climate president of Europe. Will it take it?

As the United States leans back on coal to feed its data centre boom, the Global South is racing ahead with solar, clearing the path to a decarbonised future. It’s a strange reversal in the global energy landscape – one where America’s digital infrastructure growth risks deepening dependence on the dirtiest fossil fuel, even as emerging economies embrace the clean technologies of tomorrow.

This live tracker maps the evolving patchwork of policies shaping how countries balance digital growth with environmental sustainability.
