Overview
CO2.js is a JavaScript library from The Green Web Foundation for estimating the carbon emissions of digital services. The repository describes it as an npm module for accessing the green web API and for estimating the carbon emissions from using digital services, and the documentation explains that every byte uploaded or downloaded carries a CO2 cost that developers can calculate to build more efficient, lower-carbon websites, apps and software.
Use cases
