As the world’s largest container shipping company, Maersk Line transports more than 15 percent of all shipped containers. In an industry that transports more than a third of the value of global trade—and accounts for about 4 percent of the world’s carbon emissions—Maersk Line has a tremendous economic, social, and environmental footprint. Facing pressure to reduce the company’s environmental and social impacts, Maersk Line leaders viewed this challenge as an opportunity to offer customers a value proposition on sustainability that could not be matched by competitors. Company leaders asked BSR to help develop a “future-proofed” sustainability strategy.
