At 10,000 views a month this page emits about 12.5 kg CO₂e a year, roughly 51 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 5%, and world-average grid intensity. How we calculate this

What to fix

apply everything → ~0.045 g/visit, rating A

  1. Audit third-party servicessave ~0.032 g/visit (284 kB)High impact · moderate effort

    4 third-party domains account for 568 kB (62% of the page).

    Remove services that no longer earn their place; load the rest on interaction (facades for embeds, delayed consent-gated tags). Each third party is also a privacy and performance dependency.

  2. Reduce JavaScript payloadsave ~0.021 g/visit (186 kB)High impact · moderate effort

    61 scripts total 744 kB on the wire (2.22 MB decoded). Bundles this size usually carry a lot of unused code.

    Split bundles per route, tree-shake dependencies, and audit with a bundle analyzer or coverage profile. A 25% cut is a conservative target for bundles this size.

  3. Verify your hosting energyMedium impact · moderate effort

    This host has not published renewable energy evidence with the Green Web Foundation, so its energy source is unknown.

    Choose a provider listed in the Green Web Directory, or ask your current provider to publish evidence (and a carbon.txt). This cuts the data-center share of every single page view.

  4. Upgrade compression beyond gzipsave ~0.0059 g/visit (52 kB)Advisory · quick fix

    348 kB of text ships gzip-compressed; Brotli or Zstandard would cut roughly another 15-20%, and browsers without them fall back to gzip automatically.

    Serve precompressed Brotli for static text assets (highest level, compressed at build time) and enable Brotli or zstd for dynamic responses; keep gzip only as the fallback.
