Ethical Assembly - Climate summit 2025: Reimagine our future

At the Ethical Assembly, we believe that the path to a sustainable and just future lies in the power of collective action, rooted in integrity, transparency and inclusivity. Our mission is to democratize access to the climate conversation, amplify underrepresented voices and catalyse meaningful, systemic change.

We recognize the interconnectedness of all social and environmental issues and the urgent need to act. With these principles as our guiding light, we invite you to join us in creating a world where justice and sustainability are the norm.

On the 29–30 November in #Lisbon we will have two transformative days where changemakers from all walks of life come together to reflect on pressing issues across climate change, social justice and human rights, “compost the year together” and plant the seeds of futures worth fighting for.

On 29 November, we will dive into an inspiring program of keynotes, panels, fireside chats and participatory roundtables, alongside hands-on workshops, seminars, labs, a climate bookshop, curated networking sessions and epic film screenings.

Then on 30 November, the action spreads across Lisbon and Sintra with a 5km run for the planet, a wild foraging workshop, a resistance craft lab, a seed-bomb atelier, natural wine dates with new friends and so much more (yay!).

Every moment is designed to feel restorative, joyful and deeply inspiring. We’re keeping this gathering intentionally intimate, with capacity strictly limited to 300 participants. The program is designed so that everyone can truly take part, share ideas and ask questions.

Join a vibrant mix of policymakers, scientists, innovators, activists, entrepreneurs, investors, journalists and artists coming together to tackle critical questions, explore transformative solutions, spark creativity and cultivate radical imaginaries.
