º£½ÇÉçÇø Paris and the French Government

For º£½ÇÉçÇø Paris, the Neptune Forum was an excellent opportunity to re-connect with colleagues, meet key actors operating at the intersection of science, diplomacy and policy in the emerging French and international ocean governance ecosystem, and explore joint activities.  

º£½ÇÉçÇø Paris partners, including the Government of French Polynesia, also participated in the discussion, emphasizing the deep importance of ocean governance. President Moetai Brotherson underlined:   

For us, this holds particular significance, as we are inherently an oceanic people. But even landlocked nations have a perspective shaped by the Ocean. It is an invitation for all countries to reconsider their relationship with the Ocean: when protecting it, we are protecting humanity itself.

º£½ÇÉçÇø Paris and the private sector 

Finally, on 9 June, º£½ÇÉçÇø Paris took part in a roundtable hosted by , a sustainability consultancy, on the theme "The ocean: blind spot or strategic opportunity for companies?", held at the Climate House in Paris.
