At 10,000 views a month this page emits about 2.7 kg CO₂e a year, roughly 11 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

What to fix

apply everything → ~0.0090 g/visit, rating A+

  1. Audit third-party servicessave ~0.010 g/visit (90 kB)Medium impact · moderate effort

    4 third-party domains account for 180 kB (89% 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 ~0.0040 g/visit (36 kB)Medium impact · moderate effort

    12 scripts total 143 kB on the wire (450 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.

  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.

    • carbon.txtNo carbon.txt found at the site root; publishing one is the lightest first step.
