At 10,000 views a month this page emits about 14.5 kg CO₂e a year, roughly 59 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 0%, and world-average grid intensity. How we calculate this

1. Audit third-party servicessave ~0.049 g/visit (542 kB)High impact · moderate effort

   9 third-party domains account for 1.08 MB (81% 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 ~0.018 g/visit (202 kB)High impact · moderate effort

   23 scripts total 806 kB on the wire (2.53 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. Serve images at the size they displaysave ~0.0053 g/visit (59 kB)Medium impact · quick fix

   4 images are encoded at more than twice the pixels the layout shows, even accounting for this viewport's pixel density.

   Generate multiple sizes and let the browser pick with srcset/sizes; a 4000px original behind a 400px slot spends bandwidth no screen displays.

4. Upgrade compression beyond gzipsave ~0.010 g/visit (115 kB)Advisory · quick fix

   763 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.
