We’re building an ecosystem of climate experts.
OnePointFive is driven by innovative, interdisciplinary expertise. We’re constantly sourcing cutting-edge climate intelligence to develop and execute on sustainability challenges within organizations. We thrive in the strength of uniting our diverse backgrounds, experiences and problem- solving approaches to build intentional climate solutions.
London Climate Action Week (June 20-28) is one of the most dynamic moments in 2026’s global climate calendar: bringing together city leaders, innovators, investors, and practitioners to accelerate action on both local and global levels. With hundreds of events happening across the city and online, it can be hard to know where to start.
That’s why we’ve curated a list of must-attend LCAW events recommended by our team. Whether you’re exploring the future of climate, scaling sustainability solutions, or connecting with others working at the intersection of policy and action, there’s something here for you.
🟢 Events marked as ‘OPF Team is attending’ are the ones we’ll be at (represented by OPF Co-Founder & COO, Matthias Muehlbauer), come say hi!
We've also highlighted online events in bold, so you can join the conversation and participate in LCAW no matter where you're based.
