Cork is also hosting the Oceans Wealth Summit tomorrow and Monday, focusing on the marine sector.
Speakers will include former Irish president Mary Robinson and form US secretary of state John Kerry.
Presidents, foreign ministers or UN ambassadors from 31 small island nations will also travel to Cork for the event.
Tánaiste Simon Coveney explained: "They're predominantly small island developing states - from the Caribbean, from the Pacific, from the African coast, from Asia.
"They're coming to Ireland at a very senior level - we have some presidents and ministers.
He added: "We have John Kerry coming as a guest speaker, who's probably the world's leading advocate for sustainable ocean development and protection.
"The big focus will be on climate - climate resilience for many of these islands."
