LONDON: Amazon.com Inc. and IKEA are among commercial users of container shipping that will opt for zero-carbon marine fuels by 2040 in a new initiative aimed at speeding up decarbonization in the maritime sector, executives said on Tuesday. With about 90 percent of the world trade transported by sea, global shipping accounts for nearly 3 percent of the world’s CO2 emissions and the sector is under growing scrutiny to become cleaner. The initiative, which was organized by the non-profit Aspen Institute and has nine signatories so far including others such as Unilever and Michelin, sets a goal for companies to only purchase ocean freight services powered by scalable zero-carbon fuels by 2040. “The time to act is now,” said Edgar Blanco, director, net-zero carbon at Amazon. Elisabeth Munck af Rosenschöld, sustainability manager, supply chain operations at Inter IKEA Group, said working with others was crucial for developing ocean shipping fuel solutions. “The voice of the cargo owners is important since we are one of the stakeholders to enable the transformation in the industry,” she told Reuters.
