The United States and Japan will miss a deadline on Thursday to firm up promises to provide billions of dollars for a new U.N. fund intended to help developing nations tackle global warming, the fund said.
The Green Climate Fund, which wants to decide on a first set of projects to aid developing nations before a Paris U.N. climate summit in December, said donors had signed deals of almost $4 billion, 42 percent of a total promised in late 2014.
The signed deals, which lay out a firm timetable for when promised money will be paid, are below the minimum level set by donors, of 50 percent of the total by April 30, to start full operations by the GCF.
