As we navigate significant environmental and social challenges, the return of ChangeNOW, the world’s biggest expo of solutions for the planet, is much needed to reinvigorate climate action. The 2025 edition, which will take place from April 24th to 26th, will host 140 countries, 40,000 attendees, 10,000 companies and 1,200 investors.
Visionary leaders, established businesses and start-ups alike will gather to showcase over 1,000 sustainable solutions and groundbreaking innovations in key sectors such as clean energy, biodiversity, sustainable cities and the circular economy.
The ChangeNOW 2025 summit will be held at the iconic Grand Palais in Paris, a nod to the 10th anniversary of the Paris Agreement. Reuniting for the occasion will be guest speakers Mary Robinson, the former (and first female) president of Ireland, Laurent Fabius, former French prime minister, Patricia Espinosa, former UN climate chief and diplomat and Diána Ürge-Vorsatz, leading climate scientist and professor – all of whom were in the French capital a decade earlier to help shape the Paris Agreement at COP21.
Reaffirming the spirit of Paris
There may have been obvious setbacks to environmental policy around the world of late, the United States’ recent withdrawal from the Paris Agreement being a notable one. However ChangeNOW 2025 intends to reaffirm the spirit of Paris, while serving as a catalyst for progress ahead of COP30 and the United Nations Ocean Conference (UNOC). “Ten years after COP21, ChangeNOW is where leaders and changemakers converge to accelerate the ecological and social transition,” states Santiago Lefebvre, founder and president of ChangeNOW. “Thousands of solutions will be showcased demonstrating that meaningful progress is within reach.”
His message of positive climate action will be supported by a multitude of world famous faces who will be in attendance at the auspicious event. Natalie Portman, Academy award-winning actress, director, author, activist, and producer; Captain Paul Watson, Founder of Sea Shepherd and Ocean Conservationist; Hannah Jones, CEO of The Earthshot Prize and Olympic champion boxer and gender equality advocate Imane Khelif are just a few of the names set to appear at ChangeNOW 2025.
Accelerating the transition towards a sustainable world
With over 500 speakers and 250 conference sessions exploring climate action, biodiversity protection, resource management, and social inclusion, ChangeNOW 2025 will also hear the insights of acclaimed corporate leaders from Accor, Bouygues, Henkel, Lidl, Nexans, and Saint-Gobain, who will explain how businesses can be the ones to drive real change.
And the event will not only be an opportunity for global policymakers to discuss next steps in climate action, it will also be a platform for nations to showcase local innovations through their country pavilions. Expect impactful solutions from countries including South Africa, The Netherlands, and Ukraine – demonstrating international collaboration on the topic of climate.
Platforming female changemakers and inspiring future generations
In addition to the packed program of speakers, workshops, exhibits and networking opportunities, ChangeNOW 2025 will host the Impact Job Fair on Saturday, 26 April, with over 150 recruiters and training organisations offering in excess of 600 roles. Dedicated to the public and young professionals, the interactive workshops, educational activities, and career opportunities in sustainable sectors on offer aim to inspire the next generation of changemakers.
The summit will also present the annual Women for Change conference and the accompanying portrait exhibition, which showcases 25 women who are set to have a significant positive impact on their communities, countries or on a global scale over the next 10 years. Created in 2021, the Women for Change initiative aims to platform and provide opportunities for women who are leading change around the world but require further recognition or investment to continue their work. The annual flagship event, which takes place on the afternoon of April 24th, offers women the chance to discuss new ideas, network with likeminded people, and also acquire funding to help solidify their leadership, and amplify their impact.
Sustainable solutions for our oceans, seas, and rivers
Step outside the Grand Palais and take a few steps to the Port des Champs Elysées, on the bank of the Seine, where the The Water Odyssey village awaits. One of the event’s standout features, the immersive 1,000 m² exhibition is open to the public and highlights solutions to maritime and river sustainability challenges – offering a mix of conferences, interactive displays, and sensory experiences to engage all ages.
For three days, ChangeNOW will transform Paris into the global capital of impact, bringing together policymakers, entrepreneurs, investors, and the public in the pursuit of sustainable progress.
