The French president Emmanuel Macron, along with the president of the World Bank Group, Jim Yong Kim, and the Secretary-General of the United Nations, António Guterres, called together international leaders to address climate change.
Heads of government and corporations were asked to commit to action on climate adaptation, mitigation and mobilisation.
12 commitments have been confirmed from the summit.
The Pacific will benefit from a number of these, including $US650 million from the Gates Foundation to help small-holder farmers adapt to climate change.
The Marshall Islands and New Zealand have also taken the lead in accelerating the move towards a decarbonised economy, with 16 nations committing to carbon neutrality by 2050.
The 12 commitments aim to step up finance for climate adaptation and resilience, accelerate the transition towards decarbonisation, and set climate issues as a core principle in financial decisions.
