At 10,000 views a month this page emits about 60.7 kg CO₂e a year, roughly 249 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. Lazy-load below-the-fold mediasave ~0.230 g/visit (2.54 MB)High impact · quick fix

   3 below-the-fold images/iframes (5.07 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.

2. Convert and compress imagessave ~0.216 g/visit (2.38 MB)High impact · quick fix

   4 images (5.30 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.

3. Serve images at the size they displaysave ~0.034 g/visit (379 kB)High 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. Audit third-party servicessave ~0.012 g/visit (133 kB)Medium impact · moderate effort

   3 third-party domains account for 265 kB (5% 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.

5. Optimize web fontssave ~0.0078 g/visit (85 kB)Advisory · quick fix

   4 font files total 244 kB.

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

6. Set a page-weight budgetAdvisory · moderate effort

   At 5.58 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.
