Closing the first day of the ChangeNOW World Summit in Paris, His Serene Highness Prince Albert II of Monaco delivered a message rooted in both scientific realism and economic optimism, one that reframed the environmental challenge not as a distant threat, but as a transformation already in motion.

Earlier in the day, the Prince toured the Summit’s exhibition halls alongside the forum’s two founders, M. Santiago Lefebvre and Mrs. Rose-Mary Lucotte, meeting entrepreneurs working across a broad spectrum of sectors, from energy and materials to food systems and waste management.

What distinguished the event’s showcase was not the boldness of its ambitions, but the tangible maturity of the solutions on display: initiatives grounded in science, engineering, and real-world deployment rather than mere aspiration.

The tone throughout the day was one of visible momentum. The environmental diagnosis, the Prince noted, is well known and increasingly difficult to ignore. But what also emerged across the sessions was something more instructive: evidence that the transition is no longer hypothetical. Solutions are being built, financed and deployed.

For the Prince Albert II of Monaco Foundation, the challenge has shifted accordingly. The focus now lies in helping to create conditions in which credible, scalable solutions can gain traction, attract the support they need, and extend their reach, including into domains where the need remains acute, such as the protection and restoration of the world’s oceans.

Closing his address, the Prince left delegates with a direct charge: “Do not wait for permission. Do not wait for consensus. Build it. Fund it. Scale it. The planet is keeping score, and there is no extra time.”

The ChangeNOW World Summit, held annually in Paris, brings together business leaders, policymakers, investors and innovators around solutions to the world’s most pressing environmental and social challenges.
