Digital Carbon

Your browser is quietly burning electricity and emitting CO₂. Digital Carbon shows you how much. Every video you stream, every page you load, every tab you leave open is bytes flying across data centers, networks, and your own device — and that costs real electricity. Digital Carbon counts it, request by request, and turns it into numbers you can actually feel. 🍃 See it as it happens A living ring gauge on your toolbar shows today's CO₂e, color-coded from "good" to "excessive." No dashboards to dig through — just glance and know. 🚗 Grams don't mean anything to anyone. Kilometers do. Every figure gets translated into things you already understand: kilometers driven, phone charges, minutes of a lightbulb, hours of HD streaming, even tree-minutes of CO₂ absorption. 47 grams stops being an abstraction and starts being "half a kilometer by car." 📊 Find your worst offenders The Top Sites tab ranks exactly which tabs are costing you the most — so you know whether it's that one video site or just death by a thousand ad scripts. 🌍 Powered by the real grid, not a guess Your region's actual carbon intensity — live where available (France, UK, or any zone with a free Electricity Maps key), monthly-fresh via Ember elsewhere. Browsing on a hydro-heavy grid looks very different from browsing on a coal-heavy one, and now you'll know which one you're on. 🎯 A goal that's actually yours Three quick questions on setup build a personal daily budget instead of a one-size-fits-all number — with an optional nudge when you're closing in on it. 🔒 100% local. No account, no server, no catch. Everything is calculated and stored on your device. Nothing about your browsing ever leaves it — the only network call Digital Carbon ever makes is an optional, anonymous fetch of grid carbon data, which carries zero information about you. Not a guilt trip. Not an offset scheme. Just an honest, at-a-glance estimate of the footprint that's usually invisible — so you can see it, and decide for yourself what to do with that. *Estimates are order-of-magnitude, built on public research (Sustainable Web Design methodology, IEA/Carbon Trust streaming data) — useful for building intuition, not for formal carbon accounting.*
