In a year where capital deployment defines credibility, the World Climate Investment Summit (WCIS) convenes the investors and decision-makers shaping how capital moves into the real economy of the transition.
Taking place at the London Stock Exchange on 25 June 2026, WCIS is the finance anchor of London Climate Action Week. It takes place at a critical moment following the UN Bonn Climate Conference held earlier in the month, on the road to Biodiversity COP17 in Yerevan and onto COP31 in Antalya, Türkiye, the largest climate event of the year.
Policy direction will be advanced in Bonn and WCIS will convene decision-makers across finance, policy and industry to determine how those signals translate into capital allocation, investment structures and bankable pipelines.
WCIS acts as the finance bridge between global climate policy and real economy capital deployment. By bringing together investors, policymakers and corporate leaders, we can translate climate ambition into investment at scale.
Co-organised by the World Climate Foundation and LSEG ( London Stock Exchange Group), the Summit convenes a curated group of global financial decision-makers to translate climate ambition into investment at scale.
The World Climate Investment Summit exists to close the gap between frameworks and execution and structure commitments into bankable, investment-grade opportunities.
Jens Nielsen, CEO and Founder of the World Climate Foundation, said:
“Climate and nature are no longer peripheral sustainability issues. Increasingly, they are shaping investment flows, industrial competitiveness, resilience and long-term growth. In other words, the sustainable economy is becoming the real economy, and companies need to be able to deploy capital in line with these priorities.
World Climate Foundation is supporting companies with pipeline development, policy coordination, and a global network connecting CEOs, investors, governments and innovators. That’s why the World Climate Investment Summit is so important – as a moment when we can take decisive action towards our goals.”
Why 2026 matters
Global investment is entering a decisive phase. While capital has accelerated into clean energy, critical gaps remain across energy-intensive industries, infrastructure, adaptation and nature. The sectors essential to delivering the new economy.
At the same time, geopolitical fragmentation, tightening regulation and rising physical climate risks are reshaping capital allocation. For companies, access to capital increasingly depends on credible transition strategies. For investors, decisions are being made under growing scrutiny and systemic risk exposure.
2026 marks a shift from alignment to execution. From commitments to capital deployment.
David Harris, Head of Sustainable Finance Strategic Initiatives & Partnerships at LSEG, comments:
“LSEG is proud to co-host the World Climate Investment Summit as part of London Climate Action Week, bringing together the people actually making decisions on where capital flows next.
“We’re seeing a clear shift—from financial institutions setting climate targets to actively engaging the real economy to support credible transition and resilience plans. Our role is to equip investors and the wider financial sector with the data, indices and tools they need, while connecting them with companies and investable opportunities to accelerate transformation and unlock the capital required to address the defining challenges of our time.”
WCIS is the finance anchor of London Climate Action Week
London Climate Action Week convenes global leaders across policy, finance and industry. WCIS is focused on how capital is allocated into the real economy.
On 25 June, more than 300 institutional investors, financial institutions, corporate leaders and policymakers will convene at the London Stock Exchange to address a defining question:
How does capital move into the real economy at the speed and scale required?
The Summit will focus on the sectors where capital deployment is most urgent:
Energy systems and infrastructure
Hard-to-abate industries and industrial transformation
Critical minerals and supply chains
Adaptation and resilience
Nature and emerging natural capital markets
Discussions will shape investment strategies, financing models and alignment between investors and corporate transition plans - advancing bankable pathways across the real economy.
A Single Stage Doesn’t Define Our Impact
Through our Climate Investment Coalition and Nature Investment Coalition, WCIS contributes to the broader COP Action Agenda by advancing capital mobilisation pathways and public-private collaboration across key sectors.
By convening actors with direct influence over global capital flows, the Summit converts ambition into:
Defined capital allocation priorities across key transition sectors
Investable, risk-structured pipelines aligned with investor requirements
Coalition-driven financing initiatives advancing beyond the WCIS
These outcomes carry forward through the World Climate Foundation’s 2026 Roadmap, shaping the partnerships and capital flows brought to COP31 in Antalya, Türkiye.
In a year where execution defines credibility, WCIS is where global ambition is translated into capital and connects Bonn’s agenda-setting with real-economy delivery on the road to COP31.
