At 10,000 views a month this page emits about 90.2 kg CO₂e a year, roughly 370 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 8%, and world-average grid intensity. How we calculate this

1. Audit third-party servicessave ~0.236 g/visit (2.54 MB)High impact · moderate effort

   53 third-party domains account for 5.08 MB (63% 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.

   • a.pub.network435 kB
   • assets.riverdrop.com421 kB
   • ssl.p.jwpcdn.com412 kB
   • cdn.cookielaw.org381 kB
   • www.googletagmanager.com346 kB

   WSG 3.5: Treat third parties the same as first parties
2. Reduce JavaScript payloadsave ~0.090 g/visit (966 kB)High impact · moderate effort

   74 scripts total 3.86 MB on the wire (13.18 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. Convert and compress imagessave ~0.059 g/visit (630 kB)High impact · quick fix

   22 images (1.40 MB) 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.

4. Serve images at the size they displaysave ~0.035 g/visit (373 kB)High impact · quick fix

   8 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.

5. Lazy-load below-the-fold mediasave ~0.029 g/visit (315 kB)High impact · quick fix

   18 below-the-fold images/iframes (630 kB) download 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.

6. Fix caching for returning visitorssave ~0.016 g/visit (135 kB)High impact · quick fix

   On a repeat visit 542 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.

   WSG 4.2: Optimize caching and support offline access
7. Optimize web fontssave ~0.026 g/visit (276 kB)Medium impact · quick fix

   11 font files total 787 kB.

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

8. Defer video and audioMedium impact · quick fix

   4 videos preload data without preload="none".

   Never autoload media: use preload="none" with a poster image, load players on interaction, and stream in an efficient codec (AV1/HEVC).

9. Upgrade compression beyond gzipsave ~0.027 g/visit (290 kB)Advisory · quick fix

   1.93 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. Remove references to broken resourcessave ~<0.001 g/visit (532 B)Advisory · quick fix

    4 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.

    WSG 4.4: Setup necessary error pages and redirection links
11. Set a page-weight budgetAdvisory · moderate effort

    At 8.07 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
12. Simplify the document structureAdvisory · larger effort

    The page renders 9687 DOM elements, above the 1,500 guideline. Large trees cost memory and CPU on every visitor's device.

    Flatten wrapper markup, render long lists virtually or paginate, and prefer semantic elements over nested divs.

    WSG 3.6: Ensure code follows good semantic practices
