Last year at COP28, governments committed to transition away from fossil fuels. The next key step to make good on this landmark energy agreement is rich countries agreeing to a new climate finance goal of at least $1 trillion annually to make this possible. This will allow countries to deliver national climate plans (NDCs) due in 2025 that phase out fossil fuels. Rich countries can mobilize well over $5 trillion a year for climate action at home and abroad by ending fossil fuel handouts, making big polluters pay, and changing unfair global financial rules.
