Maersk, the world’s largest shipping company, announced in August that it will add eight new container ships powered by carbon-neutral methanol, rather than “bunker” fuel.

About 90% of all globally traded goods are shipped by sea, and ships burn about 300m metric tons of fossil fuels a year and emit roughly 1bn metric tons of carbon dioxide. Researchers estimate that if zero emissions fuels comprise 5% of the international shipping fuel mix by 2030, the industry will be on a path to fully decarbonize by 2050.
