Nations agreed to a new deal Saturday that has developed countries "taking the lead" in providing up to $300 billion per year by 2035 to help vulnerable ones withstand climate change impacts and decarbonize.
Why it matters: The pact, struck at the COP29 climate summit in Baku, Azerbaijan, provides a boost from a prior goal of $100 billion per year by 2020, and allows for China and other developing nations to contribute.
