At the start of the event, US White House climate envoy and former secretary of state John Kerry said that the meeting was “so incredibly important because it is a conference that is focused on action, not on talk. It’s about real commitments and real solutions.”

Huge sums

Nearly $6 billion in US commitments spread across 77 projects to protect the high seas in 2023 was announced by Kerry, including technical cooperation to foster “green shipping corridors.”

“An agreement is being finalized with France, Spain and Cyprus for a large protected area in the extra-territorial waters of the Mediterranean, which is a great contribution to the 30×30 goal,” said Gilberto Pichetto Fratin, the Italian environment and energy security minister at the Valore Natura conference in January 2023.

The legal framework provides a crucial mechanism in setting up vast marine protected areas (MPAs) in the high seas. The historic treaty plays a critical role in the enforcement of the 30x30 pledge that countries had made in December 2022 at the United Nations Biodiversity Conference (COP15) in Montreal, Canada. The 30x30 target aims to protect a third of the sea (and land) by 2030.

The announcement by conference president, Rena Lee of Singapore, was met by a standing ovation from delegates, who had worked long days and nights to finalize the deal.
