Several governments and corporations have set long-term goals to decarbonize shipping, but currently there aren’t enough renewably powered ships to prove that these goals can be reached. This project aims to make zero emissions ships commercially competitive by 2030 and to fully decarbonize the sector by 2050 by working with a broad of coalition of advocates, analysts, communicators, and activists to accelerate the development of renewable fuels and advance policies and frameworks that can make zero emission ships and ports a reality.
