Devex IMPACT HOUSE @ London Climate Action Week

WHERE CLIMATE MEETS DEVELOPMENT — AND THE WORK OF NOW BEGINS.

Devex Impact House will be at the center of London Climate Action Week, for a day of live journalism and high-level conversations, convening the financiers deploying climate capital, the multilateral and development leaders shaping the agenda, the civil society actors holding them accountable, the philanthropists backing what others won't, and the private sector innovators building what comes next.

The climate crisis is no longer a future problem. It is a now problem, playing out in government budget negotiations, in the corridors of multilateral development banks, in the cardiac wards filling up during heatwaves, and in the fields of smallholder farmers whose crops no longer survive the season they were planted for.

The geopolitical moment has made it both more urgent and more complicated. The United States has retreated from climate diplomacy, European powers are distracted by their own crises, and ODA is contracting — even as climate shocks intensify and the communities least responsible for the crisis bear the greatest cost.

And yet the solutions are also in motion. New coalitions are forming and new capital is being deployed. Public development banks are retooling while philanthropy reorients toward climate solutions. Nature is being recognized as investible infrastructure, parametric insurance is moving from pilot to practice with a growing body of case studies showing what scaling looks like, and energy transitions are being financed in ways that can drive development, not just decarbonization. And the Global South is no longer waiting — it is demanding, and in many cases delivering, locally led solutions that are rewriting what climate action looks like.

Devex Impact House is where all those stories get told. From making the most of climate finance that will almost certainly fall short of the need, to building food systems that can withstand a warming world, from the promise and peril of AI to the intersection of climate and health. This is the room where the people doing the work come to debate, interrogate, strategize, and push forward the ideas that close the gap between ambition and action. Request your invitation.
