ChangeNOW 2025 is the world’s largest summit dedicated to solutions for the planet, designed to accelerate the transition to a sustainable future. The event is organized by ChangeNOW, an independent organization focused on amplifying and scaling innovative environmental and social impact solutions, led by its founder and CEO Santiago Lefebvre. From April 24–26, 2025, ChangeNOW will convene at the Grand Palais in Paris, France, marking the midpoint of the crucial 2020–2030 climate action decade and the 10th anniversary of the Paris Agreement.
ChangeNOW 2025 brings together over 1,000 pioneering solutions, 500+ speakers (including policymakers, business leaders, activists, and academics), and an expected 40,000 participants from more than 140 countries. The summit features thematic sessions, startup pitch competitions, and collaborative forums focused on climate action, circular economy, youth leadership, social innovation, and systemic change. Satellite events, grouped under "Planet Week Paris," expand the program from April 23–27 with citywide gatherings, exhibitions, and workshops.
The event serves as a global marketplace for impact, connecting entrepreneurs, investors, scientists, and activists to foster actionable partnerships. Major partners include HEC Paris and the Club of Rome, among others. ChangeNOW is both a platform for showcasing scalable solutions and a catalyst for cross-sector collaboration, with the goal of accelerating practical steps toward a just and regenerative future.
