The One Planet Summit, sponsored by France, the UN, and the World Bank, will draw 4000 delegates and 800 organizations to seek funding for climate projects.

The International Energy Agency (IEA) estimated that the world will spend 3.5 trillion USD a year to deal with global warming over the next 30 years. Mobilizing financial resources for climate projects is key to this effort. Postponement of action to mitigate climate change will not only lead to greater costs to address the effects, but will make the world poorer, less stable, less just, and less sustainable.

Researchers for the Heinrich Boll Fund say it will cost the world at least 300 billion USD annually until 2030 to deal with the effects of climate change. Under the Paris agreement on climate change signed in 2015, countries pledged to collectively donate 100 billion USD a year until 2020 to help poorer countries pursue clean development and adapt to climate change.

The World Bank has pledged to increase budgets for climate projects 28% by 2020. In 2017 alone, the WB pledged 13 billion USD for 200 intiatives related to climate. 60 billion USD was poured into 1000 projects to mitigate climate change in the past 5 years.

World Bank President Jim Yong Kim has said that everything will just stop at promises and no changes will be made unless enough money is raised to carry out the proposed solutions. At the One Planet Summit, nations and organizations will try to secure new financial pledges to reach the goals of the Paris Agreement.
