UNOC3: Key points to remember about renewable marine energy

The 3rd United Nations Ocean Conference (UNOC3), held in Nice from June 9 to 13, 2025, brought together more than 130 countries with a common goal: to protect the oceans while accelerating the energy and climate transition. Among the many topics discussed, marine renewable energy (MRE) featured prominently in several exchanges.

Key takeaways on MRE

• Pillar of decarbonization: MRE is recognized as essential to achieving climate goals. The Nice Action Plan identifies it as a strategic lever for sustainable energy transition, to be integrated into national and international policies.
• Acceleration of offshore wind power: during the panel discussion “Global Offshore Wind – The Next Horizon,” international players reaffirmed their commitment to scaling up the development of offshore wind power, particularly floating wind power, by focusing on industrial and technological cooperation.
• Coexistence at sea: maritime spatial planning emerged as a key issue in reconciling energy, biodiversity, and economic activities.
• Call for innovation and international cooperation: MRE is seen as a lever for innovation, with a clear need for scientific and technological partnerships between countries.
• Necessary funding: increased financial support, particularly for developing countries, is considered essential for the large-scale deployment of MRE.

UNOC3 thus confirms that marine renewable energies are establishing themselves as a strategic link in the ecological and energy transition on a global scale.
