But Wiliot, an Israel-based company, has a solution: The IoT Pixel, a stamp-sized device—costing just 10 cents each—placed on shipment boxes that transmits information about the box’s journey in real time via Bluetooth. Using proprietary software, Wiliot can then calculate the carbon footprint of shipping, storage, and more, and deliver that data to its client companies to help them analyze where they could cut emissions. The company will manufacture up to 200 million version two Pixels this year. ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/best-inventions-2023/6324560/wiliot-iot-pixel/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/best-inventions-2023/6324560/wiliot-iot-pixel/"},"headline":"Tracking Supply Chain Carbon","datePublished":"2023-10-24T11:00:35.000Z","dateModified":"2026-03-31T05:11:14.872Z","description":"","url":"https://time.com/collections/best-inventions-2023/6324560/wiliot-iot-pixel/","keywords":["list","franchise","ecommerce","Magazine","best inventions","Best Inventions 2023"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltbfae10dbe8278dd1/698a419009208f49d141ada4/best-inventions-2023-Wiliot-IoT-Pixel.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Chris Stokel-Walker","jobTitle":null,"url":"https://time.com/author/chris-stokel-walker/"}],"creator":"Chris Stokel-Walker","articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltbfae10dbe8278dd1/698a419009208f49d141ada4/best-inventions-2023-Wiliot-IoT-Pixel.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/collections/best-inventions-2023/6324560/wiliot-iot-pixel/","name":"Tracking Supply Chain Carbon"}}]}] ```
