co2.js is a JavaScript library by the Green Web Foundation that calculates the carbon footprint of digital activities, such as data transfer and web page visits. It provides multiple emission models (OneByte, Sustainable Web Design v3/v4) and supports per-byte and per-visit calculations with optional grid intensity and green hosting factors. The library also includes utilities to check if a domain is hosted on green energy via an API or local database, and to validate carbon.txt files. It is published on npm and JSR, supports Node.js, browsers, and Deno, and bundles static grid intensity data from Ember, UNFCCC, and Electricity Maps. The architecture is modular, with separate model classes, hosting check modules, and helper utilities, making components independently testable and potentially reusable in other sustainability-focused projects. The repository also contains data generation scripts for updating grid intensity data automatically via GitHub Actions.
