Under the theme “Climate Cooperation in a Fractured World”, London Climate Action Week 2026 will focus on how governments, businesses, investors and citizens can continue building the partnerships, coalitions and practical solutions needed to drive climate action forward. At the same time, London Climate Action Week showcases what people and organisations are already doing across London and the UK to deliver tangible change that benefits everyone, showing that climate action is already happening at every level, alongside progress in negotiation rooms.
Through the week, E3G will run a thought leadership series on critical issues in global climate action, focusing on climate politics, energy transition, finance, resilience and governance. Working with leading partners, these events are designed to create space for open dialogue, practical collaboration and field building between ministers, diplomats, business leaders, financiers, experts and civil society leaders at a critical moment in the international climate calendar.
E3G co-founded London Climate Action Week (LCAW) with the Mayor of London in 2019. E3G hosts LCAW and runs its own programme of flagship events during the week.

Join us for a reception at Mansion House that closes out a day focused on diplomacy, energy, and delivering the transition during London Climate Action Week 2026. It brings together guests from the State of Climate Politics Forum and the Global Energy Transition and Electrification Summit, alongside attendees from the wider Mansion House Day side events, in one of the City of London’s most iconic civic settings. Hosted by E3G as founder of LCAW and home to its year-round secretariat, alongside the Global Renewables Alliance, We Mean Business Coalition and LinkedIn, the reception is a high-energy convening moment for political, business, finance and workforce leaders shaping the economic and energy transition. It is also a moment to mark the diplomatic strand of London Climate Action Week, connecting London to the growing network of climate weeks and partners around the world.

E3G, UNIDO and DESNZ are convening ministers, industry leaders, and international institutions to focus on how the transition to greener industry can strengthen competitiveness, resilience, and long-term growth.
As governments recognise the centrality of green industries to energy security, economic development and a safe climate, attention is turning from ambition to implementation: how to scale investment, accelerate delivery, and build industrial systems of the future.
The Global Green Industrialisation Forum will comprise practical, forward-looking discussions in advance of the launch of the Global Green Industrialization Agenda at COP31.

This high-level dialogue, co-convened by E3G with British International Investment (BII), European Bank for Reconstruction and Development (EBRD) and the Country Platforms Hub, aims to connect country-owned investment approaches with the financiers and partners needed to deliver them.
Discussions will highlight what is working in practice, and what more is needed to deliver the system-level changes required to mobilise finance at scale. The Forum brings together senior government officials and ministers from finance, development co-operation and environment ministries, development finance institutions and multilateral development bank investment practitioners and private sector mobilisers, institutional investors, climate funds, and philanthropies.
Registration is by invitation only.
Thursday 25 June
At a critical time for global clean energy transition, the Information Integrity and Transition to Renewables Forum, co-convened by E3G with the UN Global Initiative for Information Integrity on Climate Change and Dalberg, aims to elevate and mainstream information integrity as central to the clean energy transition discussion and address the growing threat that information risks such climate disinformation and related tactics pose to achieving the 2050 climate goals within the Paris Agreement. Immediately following UNFCCC Bonn meetings, this event provides a key moment to reflect on policy priorities and sectorial strategies ahead of COP31 and beyond across government, private sector, academia and civil society.

Friday 26 June
Recent fossil fuel supply disruptions have highlighted the need to accelerate clean energy deployment, electrification, and trusted partnerships to enhance energy security and supply chain resilience. The India–UK Comprehensive and Economic Trade Agreement (CETA) and the conclusion of India–EU Free Trade Agreement (FTA) negotiations create new opportunities to strengthen cooperation on clean-tech manufacturing, trade, and investment. Together, these developments can support more resilient and competitive clean energy value chains while delivering shared economic benefits.
Through two interconnected high-level roundtables, jointly organised by E3G, Dalberg and Climate and Sustainability Initiative, in partnership with the UK Government. Participants will explore opportunities to strengthen UK–India, EU-India and wider international cooperation on clean energy transitions.
Registration is by invitation only.
Nearly 20 years after the UK first raised the issue of ‘climate security’ at the UNSC, join E3G and King’s College for a day of programming diving deep into the field. Headlined by a panel featuring UK Minster for Climate Katie White, EU Special Envoy for Climate Anthony Agotha, and UN Special Rapporteur on Climate Change, Elisa Morgera, this workshop will look at what challenges a changing climate brings to defence, national security, and geopolitical stability and launch a major research report.
