LCAW 2026: Climate Deals in a Fractured World

London Climate Action Week runs June 20 to 28 this year, and the timing could not be more loaded. The IEA has characterised the current global energy environment as the most severe supply crisis in modern history, compounded by active conflicts and escalating trade tensions. Politicians in the UK and abroad are openly calling for retreating from climate commitments. And yet over a thousand policymakers, investors, and founders will gather in London to do deals, build coalitions, and argue that the energy transition is not just surviving fragmentation but being reshaped by it.

This is the second fossil fuel price shock in under five years, as LCAW founder Nick Mabey noted in his framing of the event. The first, triggered by Russia's invasion of Ukraine, briefly accelerated clean energy investment in Europe before political fatigue set in. This time the context is messier: supply chain nationalism, subsidy wars between the US, EU, and China, and a global south increasingly frustrated by the pace of climate finance. The fragmentation is not a backdrop to LCAW 2026. It is the central problem the event exists to address.

IIGCC CEO Stephanie Pfeifer put it plainly: the clean energy transition has become "increasingly interlinked with global conversations about energy security and economic resilience." That linkage is the sharpest signal for capital allocators right now. Cross-border clean energy deals that would have closed smoothly in 2021 now require navigating export controls, domestic content requirements, and shifting subsidy regimes. Bloomberg Philanthropies is anchoring major climate, energy, and finance gatherings at the event, a signal that institutional capital is still showing up, but increasingly on its own terms and with harder questions about jurisdiction and counterparty risk.

For founders building in climate tech, the fragmentation story cuts both ways. Geopolitical divergence is closing some doors, particularly for hardware companies reliant on Chinese supply chains or US federal incentives now subject to political reversal. But it is opening others. Energy security has become a sovereign priority, and governments that were slow funders are now moving fast. New coalitions are forming between mid-sized economies that cannot anchor the transition alone but can co-finance it. The founders who will win in this environment are those who can structure deals across multiple jurisdictions without depending on any single policy regime to hold.

Over the next twelve months, the outcomes from LCAW will stress-test whether informal coalitions can substitute for the multilateral frameworks that are visibly weakening. Watch for shifts in where blended finance structures are being anchored, which national development banks are stepping into gaps left by stalled multilateral processes, and whether the private capital commitments made in London in late June translate into closed deals before COP31. The inflection point is real. The question is whether the institutions gathering in London are fast enough to move through it.
