At 10,000 views a month this page emits about 83.1 kg CO₂e a year, roughly 340 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

1. Convert and compress imagessave ~0.169 g/visit (1.85 MB)High impact · quick fix

   126 images (4.11 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.

2. Replace heavyweight GIFssave ~0.136 g/visit (1.49 MB)High impact · quick fix

   5 GIFs total 1.75 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.

3. Audit third-party servicessave ~0.102 g/visit (1.12 MB)High impact · moderate effort

   30 third-party domains account for 2.23 MB (30% 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. Lazy-load below-the-fold mediasave ~0.062 g/visit (678 kB)High impact · quick fix

   20 below-the-fold images/iframes (2.32 MB) 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.

5. Reduce JavaScript payloadsave ~0.034 g/visit (370 kB)High impact · moderate effort

   36 scripts total 1.48 MB on the wire (4.18 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.

6. Serve images at the size they displaysave ~0.011 g/visit (124 kB)Medium impact · quick fix

   1 image is 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.

7. Fix caching for returning visitorssave ~0.0040 g/visit (33 kB)Medium impact · quick fix

   On a repeat visit 131 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.

   • v1Cache-Control: private, max-age=0, no-store, no-cache, must-revalidate, post-check=0, pre-check=0 · 79 kB

   • favicon.icoCache-Control: public, max-age=120 · 26 kB

   WSG 4.2: Optimize caching and support offline access
8. Upgrade compression beyond gzipsave ~0.011 g/visit (121 kB)Advisory · quick fix

   808 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.

9. Stop downloading the same asset twicesave ~0.0031 g/visit (34 kB)Advisory · quick fix

   1 asset was fetched more than once in a single page load (344 kB of repeated transfer).

   Usually a script injected twice or cache-busting query strings that differ per reference. Load each asset once and let the HTTP cache do its job.

10. Set a page-weight budgetAdvisory · moderate effort

    At 7.57 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
11. Simplify the document structureAdvisory · larger effort

    The page renders 2667 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.
