Climate goals can only be realized with a major shift in financing toward low-carbon, climate-resilient assets, notably infrastructure. Progress has been made, but the world is not currently on a viable let alone a just transition pathway.

Building on such receptivity to reinforce the underlying broader purpose the financial system is a precondition for a just transition.
