At 10,000 views a month this page emits about 10.4 kg CO₂e a year, roughly 43 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 4%, and world-average grid intensity. How we calculate this

What to fix

apply everything → ~0.046 g/visit, rating A

  1. Audit third-party servicessave ~0.014 g/visit (154 kB)Medium impact · moderate effort

    5 third-party domains account for 308 kB (33% 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.

  2. Reduce JavaScript payloadsave ~0.013 g/visit (144 kB)Medium impact · moderate effort

    66 scripts total 576 kB on the wire (1.74 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 ~0.013 g/visit (138 kB)Medium impact · quick fix

    56 images (306 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.

  4. Lazy-load below-the-fold mediasave ~<0.001 g/visit (6.3 kB)Medium impact · quick fix

    20 below-the-fold images/iframes (127 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.
