Lumotraq - Ad Filter and Carbon Emission Tracker

Filter ads and measure the CO2 emissions of the ones you meet. Track your digital carbon footprint and browse more productively.

Get to know the environmental impact of the ads you see, filter the distracting ones, and turn your attention into healthier, more productive web sessions. Lumotraq is a free browser extension that estimates the carbon emissions of the digital ads you encounter while browsing: per ad, per site and per session. No account needed, no ad tracking. Just a clear number for the ads you didn't ask for, calculated with a published method. 🌱 Why measure ads instead of only blocking them? ━━━━━━━━━━━━━━━━━━━━━━━━━ - Ad blockers hide ads, but they don't show the energy already spent to deliver them to you - Lumotraq shows the CO₂ attributable to the ads you load, in grams - See which sites load the heaviest ads and decide where you spend your time 🌍 Who is it for? ━━━━━━━━━━ - Anyone curious about the environmental cost of digital advertising - Sustainability-conscious users tired of vague environmental claims in banners, videos and hidden ad content on desktop devices (PCs, laptops, tablets) - Researchers, journalists, students and everyday users who want to understand the ads behind their browsing - People who want to spot ad-heavy websites and be less distracted by ads ⚡ What do I get? ━━━━━━━━━━ A one-click popup with your current carbon count: 1) Live Carbon Counter: gCO₂e from the ads loaded in your current session. 2) Tracker Bar: a slim bar that shows the ad load on the current site. 3) Session Timer: how long your current tracked session has been running. 4) Pause / Play: one tap stops tracking; resume whenever you like. 5) Reset: archive the current session and start a fresh count. 6) Per-hour rate: your average emissions per hour, to spot intense vs. light sessions. 7) Ad Count: display, video and audio ads detected in your current session. 8) Current-site badge: the domain you're on and its CO₂ contribution, so the number stays grounded. 9) Tap-to-flip equivalents: each tile flips to a rough everyday equivalent, such as phone charges or streaming minutes. 10) Compare Mode: the current site against the other sites in your session. 11) Impact Screen: a full breakdown by ad category, with previous/next navigation. 12) Dark Mode: one-tap toggle in the menu (sage-cream light theme / deep-forest dark theme); follows your system setting on first launch. 13) Suggest a site: flag any domain we don't measure yet, straight from the menu, to help extend the public dataset. How does it work? ━━━━━━━━━━ 1. Install: no account needed. Your browser shows the permissions the extension needs before you install. 2. Browse: the extension estimates ad-related CO₂ in the background. 3. Click the icon any time to see your count. What the extension sends: anonymous usage statistics, crash reports (Sentry, EU region) and a country lookup for the electricity-grid value. Details in the privacy policy.
