Green Climate Fund Authorization Act of 2025

This bill would allow the U.S. to fund the Green Climate Fund, which helps developing countries cut pollution and prepare for climate impacts. It authorizes $4 billion per year for fiscal years 2026 and 2027 for U.S. contributions. The money would support projects built with strong protections for people, including getting consent from indigenous communities, promoting gender equality, and following environmental and social safeguards. The focus is on both reducing emissions and helping communities adapt, with an emphasis on climate and environmental justice.

The bill explains that climate change hits vulnerable and low-income communities hardest, and notes the Green Climate Fund is the world’s largest climate adaptation fund, supporting nearly 200 projects in 127 developing countries. It also points out the U.S. has contributed $2 billion so far and that the overall need for climate finance to keep warming at or below 1.5°C is much greater than the amounts authorized here.
