Measure your website's environmental impact and CO₂ emissions.

Carbon Footprint Tracking

What It Measures

Every website has an environmental impact. LemWatch estimates your site's carbon footprint based on:

Metrics

Metric — What it means —

CO₂ per visit — Grams of CO₂ produced each time someone loads your page —

Energy (kWh) — Kilowatt-hours consumed per page load —

Cleaner than X% — How your site compares to others globally —

Green hosted — Whether your server uses renewable energy —

How to Improve

  1. Optimise images — Use WebP/AVIF, compress, lazy-load
  2. Reduce JavaScript — Smaller bundles = less energy
  3. Choose green hosting — Providers powered by renewable energy
  4. Use a CDN — Shorter data paths = less energy
  5. Cache aggressively — Fewer server requests = less processing

Where to Find It

Navigate to your site's detail page and look for the Carbon tab. Data refreshes with each site check.
