London Climate Action Week harnesses the power of London for global and local climate action.
LCAW is one of the world’s largest independent climate events. Now in its eighth edition, it brings together more than 75 000 people across more than 750 events over nine days each June – from community gatherings in every borough to ministerial roundtables in the City of London, from school events to major international conferences. Climate action happening, visibly, across an entire global city.
Perspective / The heatwave that coincided with London Climate Action Week underscores the UK's urgent need to adapt to limit the threats to schools, the economy and society.

Emerging economies, including India, are exploring new energy and resource partnerships via tactical plurilateral groups, multipoint trade agreements, single-agenda deals, and even barter. Amidst technological conquests, supply chain blockades, and economic sanctions, instead of swaying with groupthink multilateralism, these countries are prioritising their own energy and resource security, and thereby, their economic and national security. This roundtable will explore the motivations, strategies, and actions of emerging economies to secure sustainable prosperity of their people.

Mothers Rise Up presents “What Comes After the Flood”, directed by Charli Willow. Our film follows the story of Tenbury Wells, a picturesque medieval town in central England, and once a sought-after place to live. Now, after a series of devastating floods, it has been ominously labelled the ‘UK’s first uninhabitable town’. Not because life there is impossible, but because homes, businesses and even the town hall are now uninsurable.
As LCAW unfolds, join us for an intimate screening of the film followed by a Q&A with contributors and affected residents and business owners.
Time: 18:00-20:00
Location: The Garden Cinema, 39-41 Parker Street, Soho, London WC2B 5PQ
Hosted by: Mothers Rise Up

At this invite-only meeting, we will explore how strategic governance can bridge the disconnect between national adaptation goals and local implementation, ensuring that national policy doesn’t just assess risk, but actively enables national leadership and local delivery. We will also offer exclusive insight into a new, national resilience approach, community case studies, and transferable lessons from the recent, global evidence symposium (funded by FCDO) on the outcomes of locally led adaptation.
