Lumotraq — Ad Carbon Emission Tracker & Sustainable Browsing

Measure CO2 emissions of digital ads you encounter. Track your carbon footprint and build more productive web sessions.

Get to know the environmental impact of ads — turn attention into healthier, more productive web sessions. Lumotraq is a free browser extension that tracks the footprint of digital ads you encounter while browsing on domains. No login, no signup, no tracking. Just instant clarity on the carbon emission cost of the ads you didn't ask for. No cookie = no question. 🌱 Why measure ads instead of blocking them? ━━━━━━━━━━━━━━━━━━━━━━━━━ • Ad blockers hide ads but ignore the energy already spent to deliver them to you • Lumotraq shows the impact in grams of CO2 — manage visible improvement • Spend less time on emission-heavy sites; reward the lighter ones with your productivity 🌍 Who is it for? ━━━━━━━━━━ • Anyone curious about the environmental cost of digital advertising • Sustainability-conscious users tired of vague claims in banners, videos or hidden content messages in desktop environments (PCs, Laptops, Tablets) • Researchers, journalists, students or common web users interested to improve their web traffic workflows by keeping up with ad signals • People who want to manage heavy emitting websites and get less distracted by ads ⚡What do I get? ━━━━━━━━━━ One-click popup with your synchronized carbon count score: - Live Carbon Counter — gCO2e score from digital ads. Delta vs. yesterday -> progress when active. - Tracker Bar — a slim progress that fills as you approach your daily goal. - Session Timer — see how long the current tracked session has been running. - Pause / Play — one tap to stop tracking instantly. Resume on your choice. - Reset — archive the current session and start a fresh count. - Per-hour rate — your hourly emissions average, useful for spotting intense vs light sessions. - Ad Count — exact display, video and audio ad totals for today - Current-site badge — the domain you're on right now plus its CO2 contribution -> the metric stays grounded. - Tap-to-flip equivalents — every tile flips on tap to a real-world unit = phone charges, streaming minutes. - Compare Mode — benchmark the current site against your daily average. - Impact Screen — full breakdown by category comparison. Previous/next navigation between examples. - Dark Mode — one-tap toggle in the menu (sage-cream light theme / deep-forest dark theme), respects your system preference on first launch - Suggest a site — flag any domain we don't measure yet directly from the menu, contributing to the public coverage dataset How does it work? ━━━━━━━━━━ 1.
