At 10,000 views a month this page emits about 15.4 kg CO₂e a year, roughly 63 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 2%, and world-average grid intensity. How we calculate this

What to fix

apply everything → ~0.084 g/visit, rating B

  1. Reduce JavaScript payloadsave ~0.019 g/visit (211 kB)High impact · moderate effort

    31 scripts total 842 kB on the wire (2.99 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.

  2. Optimize web fontssave ~0.012 g/visit (133 kB)Medium impact · quick fix

    9 font files total 380 kB.

    Subset fonts to used glyphs, prefer one variable font over multiple weights, serve WOFF2 only, and consider system fonts for UI text.

  3. Upgrade compression beyond gzipsave ~0.012 g/visit (137 kB)Advisory · quick fix

    913 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.

  4. Remove references to broken resourcessave ~<0.001 g/visit (1.8 kB)Advisory · quick fix

    22 requests answered 4xx/5xx on load: transfer and connections spent on nothing, on every single visit.

    Delete or fix the references (stale asset URLs, dead third-party tags). Each one is a request the page provably does not need.
