Enter a domain to measure the carbon weight of its advertising and tracking stack — on the live electricity grid. 55 of DACH's most-visited sites are indexed, refreshed monthly.
A snapshot of the advertising and tracking carbon loaded by the region's most-visited homepages — the public part of the index.
CO₂ per million pageviews — the average ad-tech footprint of a DACH homepage, measured on the live grid.
of that footprint isn't the ads at all — it's tracking, tag managers and consent banners loading in the background.
more ad-carbon on a news homepage than a government one — ad-complexity, not page weight, is what drives it.
the heaviest site measured (orf.at) — about 6.6× the DACH average, per million pageviews.
Ad-funded content categories load the most ad-tech; government and public-service sites load almost none.
Government sites sit ~66× lower. Measure a site above to see where its sector lands across all eight categories.
