DUBAI (Reuters) -The United States has pledged $3 billion to the Green Climate Fund, Vice President Kamala Harris said on Saturday as she arrived in Dubai for the U.N. climate summit.
The fund, with more than $20 billion in pledges, is the largest international fund dedicated to supporting climate action in developing countries.
The latest pledge, which Reuters was first to report, would be additional to another $2 billion previously delivered by the United States.
Sources said the pledge was subject to the availability of funds. The politically divided U.S. Congress needs to authorize the funding.
Harris announced the pledge in advance extracts of her address to the COP28 summit.
"Today I am proud to announce we will make a new $3 billion pledge to the Green Climate Fund which helps developing countries access the capital they need to invest in resilience, clean energy, and nature-based solutions," the extracts said.
The fund's facilitators said in October that the current second round of replenishments had brought in about $9.3 billion in pledges to fund projects in climate-vulnerable counties between 2024 and 2027.
Even so, pledges so far represent a fraction of roughly $250 billion that developing countries would need every year by 2030 just to adapt to a warmer world, according to the United Nations. In addition to supporting climate adaptation, the fund also finances projects to help countries shift to clean energy.
A U.S. climate official said the vice president would tell the summit that the world needs to "make sure that everybody is at the table, and everybody is stepping up. Everybody has to step up."
Harris, who is representing the United States at COP28 in place of President Joe Biden, is part of a U.S. delegation that also includes climate envoy John Kerry and dozens of senior administration officials and cabinet members.
"It was important for both the president and vice president to ensure that a leader from the United States was at COP," an official said, adding that Harris wanted to “make sure we are telling the world the story of progress that we have made in the U.S."
