At 10,000 views a month this page emits about 357.7 kg CO₂e a year, roughly 1466 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 91%, and world-average grid intensity. How we calculate this

1. Replace heavyweight GIFssave ~2.28 g/visit (15.78 MB)High impact · quick fix

   1 GIF totals 18.57 MB. GIF is the least efficient image format still in common use, animated or not.

   If it animates, re-encode the clip as a muted looping MP4 or WebM (typically a 10x reduction); if it is a still, convert it to WebP or AVIF.

2. Fix caching for returning visitorssave ~0.688 g/visit (4.64 MB)High impact · quick fix

   On a repeat visit 18.58 MB 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.

3. Audit third-party servicessave ~0.456 g/visit (3.15 MB)High impact · moderate effort

   8 third-party domains account for 19.30 MB (94% 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.

4. Reduce JavaScript payloadsave ~0.055 g/visit (380 kB)High impact · moderate effort

   254 scripts total 1.52 MB on the wire (4.23 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.

5. Convert and compress imagessave ~0.011 g/visit (78 kB)Medium impact · quick fix

   4 images (173 kB) ship in legacy formats (JPEG/PNG/GIF).

   Serve AVIF (or WebP) with responsive srcset sizes, and re-compress oversized files. AVIF typically halves JPEG weight at the same visual quality.

6. Lazy-load below-the-fold mediasave ~<0.001 g/visit (5.6 kB)Medium impact · quick fix

   1 below-the-fold image or iframe (112 kB) downloads immediately for every visitor.

   Add loading="lazy" to below-fold img and iframe elements (and keep it off the LCP image). Browsers then fetch them only when scrolling approaches.

7. Serve images at the size they displaysave ~<0.001 g/visit (771 B)Medium impact · quick fix

   3 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.

8. 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.

9. Upgrade compression beyond gzipsave ~0.030 g/visit (208 kB)Advisory · quick fix

   1.39 MB 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.

10. Optimize web fontssave ~0.0047 g/visit (32 kB)Advisory · quick fix

    6 font files total 92 kB.

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

11. Set a page-weight budgetAdvisory · moderate effort

    At 20.59 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.
