At 10,000 views a month this page emits about 5.4 kg CO₂e a year, roughly 22 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 → ~0.027 g/visit, rating A+

  1. Audit third-party servicessave ~0.0095 g/visit (85 kB)Medium impact · moderate effort

    2 third-party domains account for 170 kB (42% 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 ~0.0094 g/visit (84 kB)Medium impact · moderate effort

    14 scripts total 336 kB on the wire (1.06 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. Verify your hosting energyMedium impact · moderate effort

    This host has not published renewable energy evidence with the Green Web Foundation, so its energy source is unknown.

    Choose a provider listed in the Green Web Directory, or ask your current provider to publish evidence (and a carbon.txt). This cuts the data-center share of every single page view.
