Explore London through the lens of nature, climate, creativity, and community. Each month, The Green Londoner curates a small but hopefully helpful list of the city’s most inspiring green events.
This June is packed with opportunities — from nature walks and urban festivals to exhibitions and hands-on workshops. We’re proud to be a media partner for Earthfest and supporting media partner for London Climate Action Week, and we’ll also be hosting two events: one for Outdoor Office Day (12 June) and another on 27 June (more details coming soon!).
The Green Londoner will also be sharing two special calendars to help you navigate the season:
• Our Top 10 picks for Earthfest (talks, workshops, and more)
• A curated guide to London Climate Action Week, helping you find your way through 400+ events across the city
