Nature loss and climate change are no longer distant risks. Business, finance, and society all face direct consequences from these accelerating crises. With global frameworks setting a clear direction, the years leading up to 2030 are critical for translating commitments into tangible actions.

This is a working space to accelerate change, shape leadership, and unlock sustainable growth while halting and reversing nature loss.

  • Aligning financial flows
  • Integrated solutions

Nature Tech Collective and LSE Generate

Nature Tech Unconference

London School of Economics, London (UK)

Thursday 14th May 2026 - Friday 15th May 2026
London (UK)

The Nature Tech Unconference brings the full sector into one room: the builders, the capital, the science, and the policy. Co-hosted with LSE Generate at the London School of Economics, 35 sessions over two days, shaped entirely by the people in them.

Why: The unconference format puts the agenda in your hands. Come ready to contribute, push back, and leave with more clarity than you arrived with. These aren’t panel discussions. They’re working sessions built for people who want to move things forward.

Built by the Nature Tech Community: Every session on the programme came from someone in this community with something worth exploring. Researchers, investors, field practitioners, and policymakers, all bringing the questions the sector hasn’t cracked yet. That’s who you’ll be in the room with.
