At 10,000 views a month this page emits about 56.3 kg CO₂e a year, roughly 231 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 3%, and world-average grid intensity. How we calculate this

1. Enable text compressionsave ~0.166 g/visit (1.47 MB)High impact · quick fix

   23 text resources (2.11 MB) are served without gzip/Brotli.

   Enable Brotli (or at least gzip) on the server or CDN for HTML, CSS, JavaScript, JSON and SVG. Typical reduction is ~70%.

   • PhoneFormat.js385 kB
   • jquery-ui-1.12.1.min.js255 kB

2. Audit third-party servicessave ~0.097 g/visit (864 kB)High impact · moderate effort

   28 third-party domains account for 1.91 MB (46% 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.

   WSG 3.5: Treat third parties the same as first parties
3. Reduce JavaScript payloadsave ~0.087 g/visit (771 kB)High impact · moderate effort

   36 scripts total 3.08 MB on the wire (6.52 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.

4. Optimize web fontssave ~0.015 g/visit (130 kB)Medium impact · quick fix

   5 font files total 370 kB.

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

5. Fix caching for returning visitorssave ~0.0035 g/visit (24 kB)Medium impact · quick fix

   On a repeat visit 94 kB of static assets were re-downloaded instead of coming from cache.

   Serve static assets with Cache-Control: public, max-age=31536000, immutable and versioned filenames so returning visitors download almost nothing.

   • _club.svgCache-Control: max-age=604800 · 6.0 kB

   • collectno Cache-Control header · 723 B
   • 0Cache-Control: no-cache, must-revalidate · 120 B

   WSG 4.2: Optimize caching and support offline access
6. 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.

   • carbon.txtNo carbon.txt found at the site root; publishing one is the lightest first step.

   WSG 4.1: Use sustainable hosting
7. Upgrade compression beyond gzipsave ~0.010 g/visit (91 kB)Advisory · quick fix

   608 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.

   • full-beacon-init.41a52991.chunk.js123 kB
   • 974615061559213122 kB
   • fbevents.js110 kB
   • porkbun.com37 kB
   • main.js28 kB

   WSG 4.3: Reduce data transfer with compression
8. Set a page-weight budgetAdvisory · moderate effort

   At 4.18 MB per view this page rates F. The findings above list where the weight is.

   Agree a transfer budget (e.g. under 975 kB reaches a B), enforce it in CI, and re-scan after each change to hold the line.

   WSG 3.1: Set goals based on performance and energy impact
9. Upgrade connections to HTTP/2 or HTTP/3Advisory · quick fix

   1 host serves five or more resources over HTTP/1.1, paying per-request connection and header overhead newer protocols eliminate.

   Enable HTTP/2 (or HTTP/3) on the server or move the assets behind a CDN that speaks it; multiplexing makes many small requests nearly free.
