Industry perspectives on sustainable advertising.

What does Lumotraq actually measure?

Lumotraq measures the carbon footprint of digital advertising you see while browsing — the energy used by ad servers, content delivery networks, and your device to render each ad. Estimates are reported in grams of CO₂ equivalent per impression and aggregated into your daily total.

Where do the CO₂e figures come from?

Our calculations combine published methodologies from the Ad Net Zero Global Media Sustainability Framework and the GHG Protocol with country-specific electricity-grid data. Each ad format and device type carries its own emission factor, sourced from peer-reviewed industry research.

How accurate are the carbon estimates?

Estimates are approximations, not certified measurements. They are accurate enough to compare ads, channels, and websites against each other and to track changes over time, but should not be reported as exact figures for compliance purposes without further verification.

Can I cancel anytime, and what happens to my data?

Yes — you can uninstall the extension or close your account at any time. Account deletion removes your synced data within 30 days, and server logs are retained for 90 days for security before being erased. Local extension data lives only on your device and is wiped when you uninstall.
