Major retailers, including Amazon and Ikea, are beginning to clean up their shipping pollution. A group of companies pledged recently that by 2040, they’ll only contract ships using zero-carbon fuels to move their goods. Joining Amazon and Ikea in the commitment are Unilever, Michelin, and clothing retailer Inditex, which owns Zara and other brands. German retailer Tchibo, Patagonia, sports gear company Brooks Running and FrogBikes are part of the deal too. The aim is to leave behind heavy fuel oil in favor of alternatives that don’t release planet-heating carbon dioxide. “This will be a catalyzing force and a game-changer for the industry to really push for the decarbonization of the sector,” said Kendra Ulrich, shipping campaigns director at the environmental nonprofit Stand.earth.
