Taking a stance on societal or environmental problems is key to advocacy-based business models. Maersk, the pioneer in container shipping that enabled global trade, pledged to pursue decarbonization of ocean transport. The company signed nine agreements to produce green methanol and successfully launched “ECO Delivery,” then the only carbon-neutral shipping option in the industry. Between 2019 and 2022, the demand for ECO Delivery grew 170% year-on-year, driven by Maersk’s largest customers, which include Nike, H&M, Disney, Novo Nordisk, BMW, and Volvo.
