Measuring Carbon Footprint
We render the page and measure every resource that contributes to its carbon intensity
Rendering page in headless browser...
Measuring page weight & resources...
Analyzing ad load & supply chain...
Computing carbon grade & recommendations...
This typically takes 20–60 seconds — a real browser render plus full resource analysis. Worth the wait.

Carbon Footprint API Demo

Score any URL 0–100 for digital carbon intensity. The score combines page weight analysis, ad-load measurement, video and rich-media detection, supply-chain complexity and hosting efficiency — graded A through F with estimated CO₂ per impression.

This demo runs our full carbon intensity scoring pipeline on any URL: a headless-browser render, resource measurement, ad-stack analysis and hosting efficiency checks. To scale up, integrate the API endpoint or learn how carbon scoring works.
No URL at hand? Try one of these examples — a heavy media site next to a minimal one — and watch the carbon grade separate them:
cnn.com — heavy media heavy buzzfeed.com — ad-heavy heavy wikipedia.org — minimal green bbc.com/news — moderate moderate

Page Weight Analysis
Total page transfer size, resource breakdown by type, unoptimized images and font payload — the raw material cost of every impression.
Ad Load Impact
Ad scripts loaded, header bidding activity and ad refresh detection — the carbon overhead of monetization infrastructure.
Video & Rich Media
Autoplay video detection, known video platforms, video ad players and rich media frameworks — the heaviest carbon contributors.
Hosting Efficiency
Hosting provider green energy commitment, HTTP protocol version, compression and cache header analysis.
