President Biden and His Majesty King Charles III met at Windsor Castle with 23 leading philanthropists and financiers to help catalyze finance to support emerging markets and developing countries in tackling the climate crisis. The gathering followed the Climate Finance Mobilization Forum, which was convened by the UK Energy Security and Net Zero Secretary Grant Shapps and U.S. Special Presidential Envoy for Climate John Kerry, and inspired by the work of His Majesty the King.
