Tides of Change: Nice hosts the UN Ocean Conference

Nice is preparing to host a gathering that could shape the future of our planet's oceans. From the 9th to the 13th June 2025, the Third United Nations Ocean Conference (UNOC3) will convene here, bringing together world leaders, scientists, activists and citizens to address the escalating crisis facing our marine environments.

The choice of Nice as the venue is both symbolic and strategic. Nestled along the French Riviera, the city embodies the delicate balance between human development and natural beauty. Its location at the heart of the Mediterranean, a sea that has witnessed both the rise of civilizations and the degradation of marine ecosystems, makes it an apt setting for discussions on ocean conservation.

The urgency of this conference cannot be overstated. Despite covering more than 70% of the Earth's surface, our oceans are under unprecedented stress. Climate change has led to rising sea temperatures, causing coral bleaching and disrupting marine life. Overfishing, pollution and habitat destruction further exacerbate the problem, threatening the livelihoods of billions who depend on the sea for food and income.

UNOC3 aims to address these challenges head-on. One of its primary goals is to accelerate the implementation of Sustainable Development Goal 14: to conserve and sustainably use the oceans, seas and marine resources. Key objectives include the ratification of the Marine Biological Diversity Treaty, which seeks to protect biodiversity in areas beyond national jurisdiction and the elimination of harmful fishing practices like bottom trawling, which not only devastate marine habitats but also release significant amounts of carbon dioxide, exacerbating climate change.

The conference also aims to mobilize substantial financial commitments. Organizers anticipate securing $100 billion in new funding to support ocean conservation initiatives, signalling a significant investment in the planet's future. This financial mobilization is crucial, as it will enable the establishment and management of Marine Protected Areas (MPAs), support sustainable fisheries and promote research and innovation in marine science.

Hosting such a significant event brings both opportunities and challenges for Nice. On the positive side, the influx of delegates and tourists is expected to stimulate the local economy, benefiting hotels, restaurants and other businesses. The city's global profile will be elevated, potentially attracting future events and investments. Moreover, Nice's active participation in global environmental initiatives reinforces its commitment to sustainability and positions it as a leader in climate action.

However, the conference will also necessitate adjustments in daily life for residents. Starting on the 5th June, areas around the Promenade des Anglais and the port will experience limited access, with residents required to provide proof of address. Parking will be restricted in certain zones. To alleviate congestion, all Lignes d’Azur buses and trams will be free from the 6th to the 8th June, encouraging the use of public transport. Additionally, from the 6th to the 10th June, general aviation operations at Nice Côte d’Azur Airport will be reserved exclusively for UN and official delegation flights, affecting private and business aviation schedules.

Despite these logistical challenges, the conference offers numerous opportunities for public engagement. On the 6th June, the city will host free concerts featuring top DJs Agoria and Cassius at the Quai des États-Unis, followed by a record-breaking drone show with 2,025 drones illuminating the night sky. Throughout June, various exhibitions and discussions focusing on ocean conservation will be open to the public, fostering awareness and community involvement.

The outcomes of UNOC3 are expected to be significant. The conference will adopt the Nice Ocean Action Plan, a declaration recognizing the oceans' crucial role in sustaining life and emphasizing the slow progress on climate change, biodiversity loss and pollution. This plan aims for zero rhetoric and maximum results in ocean conservation, setting a clear roadmap for future actions.

In conclusion, the UN Ocean Conference in Nice represents a critical juncture in our collective efforts to safeguard the oceans. While the city faces short-term disruptions, the long-term benefits, be they economic, environmental and reputational, are substantial. By embracing its role as host, Nice not only contributes to vital international discourse but also sets a precedent for urban engagement in global sustainability initiatives.
