At 10,000 views a month this page emits about 6.6 kg CO₂e a year, roughly 27 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 1%, and world-average grid intensity. How we calculate this

What to fix

apply everything → ~0.022 g/visit, rating A+

  1. Audit third-party servicessave ~0.019 g/visit (214 kB)Medium impact · moderate effort

    4 third-party domains account for 428 kB (70% 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. Optimize web fontssave ~0.013 g/visit (148 kB)Medium impact · quick fix

    5 font files total 422 kB.

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

  3. Reduce JavaScript payloadsave ~0.0038 g/visit (41 kB)Medium impact · moderate effort

    2 scripts total 166 kB on the wire (515 kB 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.
