CNN — Japan’s flag carrier has started a year-long trial of a service that allows travelers to book a set of clothes — covering different sartorial styles and seasons — and receive it at their hotel upon arrival. At the end of the stay the clothes are returned, to be washed and cycled back into the system. Called Any Wear, Anywhere, the service runs through the end of August 2024 and Japan Airlines says it could cut carbon emissions by reducing the weight carried by its airplanes.
Cutting weight, cutting emissions? Weight reduction is a proven way to save fuel and reduce emissions, and it’s been factored in by aircraft manufacturers and airlines for a long time, for example by designing lighter passenger seats or replacing heavy paper manuals with tablets. Even small changes can have a large impact: when Qantas redesigned its tableware for first and business class to be just 11% lighter, the company says it started saving 1.1 million pounds of fuel per year.
