Ethical Assembly

The Ethical Assembly is an independent global platform advancing climate leadership and collective action for a just and sustainable future. Our mission is to democratise access to the climate conversation, inspire collaboration across sectors, borders and generations and foster systemic solutions. Since 2019, our climate summits and community events have brought together over 3,500 participants, 300 international speakers and 250 partner organisations from all over the world. We convene policymakers, scientists, financiers, entrepreneurs, researchers, grassroots movements, journalists, activists and civil society to address the interconnected crises of climate, social, racial, gender and class justice. Through roundtable discussions, keynotes, panels, fireside chats, workshops, tech showcases, art installations, film screenings and live concerts, the Ethical Assembly provides a cross-disciplinary, intersectional space for honest dialogue, learning and action. We challenge extractive systems, amplify underrepresented voices and nurture powerful alliances. Our goal is to break down silos and highlight the interdependencies and shared responsibilities across sectors, from clean energy and regenerative agriculture to ethical fashion, ocean health, green finance and circular economy. Without investors, big sponsors or pay-to-play content, and with a firm commitment to a greenwashing-free agenda, the Ethical Assembly is a trusted platform where integrity, accountability and impact come first. Past speakers include UN Champion of the Earth Leyla Acaroglu, climate activist and Star Wars actress Lily Cole, Plastic Pollution Coalition founder Diana Cohen, big-wave surfer Garreth McNamara, conservationist Robin Moore and Patagonia ambassador Dr. Tony Butt.
