A group of brands including Amazon, IKEA, Michelin, Patagonia and Unilever have signed up to the Cargo Owners for Zero Emission Vessels (coZEV), a new collaborative, cargo owner-led network facilitated by the nonprofit Aspen Institute. This sends a powerful demand signal "to the shipping industry and bunker fuel producers that freight customers want zero-carbon shipping and they expect the industry to rapidly accelerate its decarbonization efforts in the years ahead," the Aspen Institute says. Maritime shipping currently accounts for 3% of all global emissions, and could rise to 10% by 2050 if the industry continues to rely on carbon-intensive fuels.
