FAQ's
How can I find out which events are free to attend?
The official website features a comprehensive event directory that allows you to filter the hundreds of sessions by category and cost. Many of the community-led workshops, public art displays, and online webinars are completely free of charge to ensure maximum accessibility. However, some of these free events still require advance registration through the individual host’s ticketing platform to manage venue capacity.
Are the events strictly for climate professionals?
While many sessions are technical and aimed at experts in finance or science, a large portion of the program is designed for the general public. There are cultural events, film screenings, and educational activities specifically created to engage people who are new to climate issues. The diversity of the program ensures that anyone with an interest in the environment can find something valuable and understandable to participate in.
Is there a central hub where I can meet other participants?
Because the festival is city-wide, there is no single central building, but several "hubs" like the Guildhall and The Conduit host multiple events and networking zones throughout the week. These hubs act as meeting points for attendees to gather between sessions and share ideas in a collaborative environment. Check the official hub listings to find the location that best aligns with your specific industry or personal interest.
Can I host my own event during London Climate Action Week?
Organizers are encouraged to submit their own climate-themed events to be included in the official programme as long as they meet the event's core values. Registration for 2026 typically opens in the spring, and hosts are responsible for their own venue and logistics. Inclusion in the official directory provides significant visibility to a global audience of climate-conscious participants and media.
What is the best way to travel between different venue locations?
The London Underground and bus networks are the most efficient ways to travel between the various hubs scattered across the city. Most major venues are located near key stations, and the city’s cycling infrastructure also provides a sustainable way to move between sessions. Since the event promotes climate action, using public transport or walking is the preferred and most practical method for all attendees.
