Everything you need to know London Action Climate Week

London Climate Action Week (LCAW) is an annual event harnessing the power of London for global and local climate action. Founded in 2019, LCAW is one of the world’s largest independent climate events. It brings together more than 75,000 people across more than 750 events over nine days each June.

LCAW is a key moment in the global climate calendar, where climate action happens between COPs, where the UN Global Climate Action Agenda comes alive in cities and communities, and where the international climate community gathers to build the cooperation for progress and action.

The LCAW Secretariat provides an open and inclusive platform, while event organisers are responsible for organising and hosting their own events. Events can take place at any time and place during the LCAW dates — in-person, hybrid, or virtual, in London and internationally with partners. From panel discussions and conferences to workshops, cultural gatherings, and art installations, the choice of format is open to organisers to design as appropriate to their desired outcomes.

There are few barriers to participation – we ask that event organisers align with the ethos of what we are co-creating. All voices are welcome, but we do not encourage events that benefit from the sponsorship or direct financial support of businesses, organisations or groups that are antagonistic to the need for climate action and a net zero future. Likewise, we expect organisers to embrace the rich vibrancy and diversity of London and her communities, and ensure climate action brings people together, emphasising climate justice, humanity and equality. London Climate Action Week is collaborative and inclusive, ambitious, and solutions focused. We cannot accept events which are financially sponsored by fossil fuel companies or which undermine climate ambition.

Event registration for 2026 is now open and will close on June 12. You can submit your event via our “event registration” portal on the website. Due to high volume, reviews and publication may take 5+ days.
All event organisers are invited to apply, and submissions will be reviewed by the LCAW Secretariat in accordance with our terms and conditions.

Organisers have full flexibility over their event format, platform, duration, and audience. A few things to note:

  • Access: Events can be public and open to all, or private for a specific group.
  • Ticketing: Organisers can choose to make their event free or charge attendees. This should be made clear in your invitation process.
  • Format & platform: Organisers decide on the format and platform most suitable for their event. Note that the LCAW Secretariat is unable to provide technical assistance.
  • Duration: Organisers decide on the length of their events and can run multiple events. For virtual events, timeslots of 1–1.5 hours are recommended.
  • Cost: Participation in LCAW is free of charge. Organisers are responsible for covering their own event costs and promotion.

All assets for event hosts are stored in our Google Drive. In the Drive, you will find the digital toolkit folder, which includes LCAW logos, social media assets and templates.

Flagship events of LCAW are chosen each year by the LCAW secretariat based on the following factors:

  • Flagships (individually and as a group) are exemplar events that represent, animate and make a tangible contribution to climate conversations and priority action across LCAW themes, sectors and focus areas.
  • Events that amplify and enhance the LCAW story, identity and platform.
  • Events that live the LCAW ethos, through collaboration, innovation and inclusiveness. Organisers demonstrate an active commitment to contributing to and supporting LCAW and its community, through offering in-kind space, time and expertise, deploy their networks and outreach, convene and curate and support the overall development of LCAW.
  • Organisers should also clearly demonstrate their own climate action.

You can browse the full programme on the LCAW website. Please note that LCAW does not have centralised registration. Participants need to register directly with individual events.

Yes. To find collaboration opportunities, please take a look at our collaboration tracker, where we store and share contact details of people seeking or offering speakers, venues, or co-hosting opportunities. Use the password ‘LCAWcollab2026’ to access the document.

  • Looking for a speaker or venue? Browse the relevant tabs in the tracker for contact information.
  • Want to be listed as a speaker or venue? Email info@londonclimateactionweek.org with your details following the tab format and the subject line “Speaker Registration” or “Venue Registration”.

All materials and resources for stakeholders — including the digital toolkit, stakeholder briefing recordings, and the collaboration tracker — are also stored in our shared Google Drive.

LCAW is a festival of stakeholder-run events, so speaking opportunities are managed directly by event organisers. We recommend browsing the collaboration tracker (see above) to find organisers seeking speakers, or listing yourself as an available speaker by emailing info@londonclimateactionweek.org with the subject line “Speaker Registration”.
As the LCAW Secretariat, we only get directly involved in the organisation of a small number of events and therefore have limited direct speaking opportunities.

The LCAW Secretariat hosts regular stakeholder briefings to share the latest new about LCAW. All materials from past briefings – including slides, recordings, and chat transcripts – are stored in our shared Google Drive. Please sign up to our mailing list to be notified of upcoming briefings.

LCAW has introduced hubs, free or discounted spaces available for hosting events and networking.

A document with the list of hubs under development is available in the Google Drive, and the full list will also be published on the website shortly.

 

London Climate Action Week will convene communities and citizens from across London. It aims to be a unifying moment shaping a “whole of society” response to the climate emergency. To that end, we ask that event organisers align with the ethos of what we are co-creating. All voices are welcome and we expect organisers to embrace the rich vibrancy and diversity of London and all of its communities, and ensure climate action brings people together, emphasising climate justice, humanity and equality.

LCAW asks all organisers to consider the wider diversity of speakers at their events, including ethnicity, disability, and age. Make reasonable attempts to secure a diverse line-up of speakers; this aim can be more easily met by having a balance of reserve candidates, consulting potential speakers before the final date is set, and contacting speakers sufficiently in advance to allow for any child care needs that may be necessary.

All LCAW organisers, and speakers are expected not to knowingly use language which may be deemed to be discriminatory or offensive to any participants. All organising companies/bodies are expected to be tolerant of the beliefs of others and be sensitive to the influence of ethnic and cultural background, the needs of those with disabilities and issues related to gender, marital status, sexuality, socio-economic background and age.

London has a world-leading concentration of climate professionals working in the public, private and knowledge sectors – as well as in charities and not-for-profit organisations – with local, national and international reach.

London Climate Action Week was forged to bring these actors and organisations together to enhance collaboration and the creation of an ambitious and active London “climate cluster”. Climate change is a systemic challenge requiring all sectors and disciplines to work more closely together to develop and scale-up innovative solutions at pace.

As one of the world’s major cities, London’s citizens and communities – in the widest sense – are increasingly aware of the urgency of the need for climate action. Climate change is an existential threat, requiring an “all of society response” that acknowledges and welcomes the diversity of perspectives and experiences of Londoners.

As many Londoners have international heritage, connections and experience, we expect London Climate Action Week to have a global perspective with culturally rich events and initiatives that have impact and outcomes that are felt far beyond London’s geographic boundaries.
