    Carbon Footprint Tracking#

    What It Measures#

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

  1. Page size — Larger pages require more energy to transfer
  2. Green hosting — Whether your server runs on renewable energy
  3. Data transfer — CO₂ produced per page load
  4. Energy consumption — Estimated kWh per visit
  5. Metrics#

    How to Improve#

  6. Optimise images — Use WebP/AVIF, compress, lazy-load
  7. Reduce JavaScript — Smaller bundles = less energy
  8. Choose green hosting — Providers powered by renewable energy
  9. Use a CDN — Shorter data paths = less energy
  10. Cache aggressively — Fewer server requests = less processing
  11. Where to Find It#

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