In the spirit of maintaining a sense of control and purpose in a time of ever-increasing climate anxiety, you might be embracing subtle lifestyle changes to reduce your carbon footprint. Perhaps you've incorporated flexitarian eating, cut down on single-use plastics and are relying less on cars for transportation. Some people, however, are making more of a splash. Bidets — specialized bathroom fixtures that rinse your rear — are making a comeback, and new affordable attachments mean they're more accessible than ever. Beyond the thorough cleaning perks, bidets are often marketed as being more environmentally friendly than using toilet paper, with manufacturing companies claiming bidets can save trees, water and reduce your carbon footprint.
