Lumotraq — Ad Carbon Emission Tracker & Sustainable Browsing

Tracking since Apr 30, 2026.

Changelog

• Jun 5, 2026
  description

  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. Install — no signup, no permission requests required
  2. Browse  — the extension counts ad-related CO2 emissions in the background
  3. Click the icon any time to see your count for the current ads
  
  Read the full methodology: https://lumotraq.com/methodology
  
  
   🛠 To be done
  ━━━━━━━━━━
  
  Feedback is valuable. If you got a suggestion, quick notes to catch up or just some positive words to share. Feel free to contact Lumotraq at [email protected].

  Lumotraq estimates the carbon footprint of digital ads served to you during browsing. We detect ad elements on pages via content scripts and use location data to apply the correct data. It detects banner, video, and sponsored ads across the context that matters: news, streaming, shopping and work. Each ad is matched and converted to CO₂e using methodology grounded in a verified protocol and framework. Under modern consent workflows your carbon score reflects which ads actually rendered on your screen when active.
  
  Every page you load might run ads. Each of these is linked to a network request, script, video frame or tracking pixel — quietly consuming bandwidth, processor cycles and battery. For consumers, it's an visible drag on device performance and personal media footprint. For businesses, it's an measured Scope 3 line item under CSRD obligations with more accuracy, transparency and opportunity for scale. What all three have in common? The option to manage wasted time, lost productivity and weighted ad consumption based on web traffic online.
  
  Climate-conscious consumers who want to see the environmental cost of their daily media consumption do benefit from managing their emissions by reflecting lost space for productive engagement. Sustainability-oriented users who care about measurement, do benefit from privacy oriented ad filtering. Marketing operations leads, ad-technology professionals and publisher teams who are using similiar approaches for media reporting, submitting reviews or CSRD Scope 3 reporting take the first step of more effective work on reliable sources.
  
  Anonymized error reports secure stability and operational monitoring. Anonymized feature-usage aggregates approves analytics. Processing complies with GDPR, EU-hosted backend is supported. Lumotraq is currently available in markets where reliable data is accessible. We are expanding coverage market-by-market as soon as possible.

  Lumotraq estimates the carbon footprint of digital ads served to you during browsing. We detect ad elements on pages via content scripts and use your location (derived from IP,  country-level only) to apply the correct electricity grid intensity. It detects banner, video, and sponsored ads across the context that matters: news, streaming, shopping and work. Each ad is matched to your country's electricity grid intensity, then converted to CO₂e using methodology grounded in the GHG Protocol (Scope 3) and Ad Net Zero's Global Media Sustainability Framework. Under modern ad-consent frameworks your carbon score reflects what actually rendered on your screen during the session.
  
  Every page you load might run ads. Each ad is linked to a network request, script, video frame or tracking pixel — quietly consuming bandwidth, processor cycles, and electricity grid CO₂e.
