At 10,000 views a month this page emits about 32.8 kg CO₂e a year, roughly 135 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 10%, and world-average grid intensity. How we calculate this

1. Reduce JavaScript payloadsave ~0.033 g/visit (291 kB)High impact · moderate effort

   68 scripts total 1.16 MB on the wire (3.71 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.

2. 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.

3. Optimize web fontssave ~0.0054 g/visit (47 kB)Advisory · quick fix

   4 font files total 134 kB.

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

4. Set a page-weight budgetAdvisory · moderate effort

   At 2.38 MB per view this page rates D. 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.

5. Simplify the document structureAdvisory · larger effort

   The page renders 3664 DOM elements, above the 1,500 guideline. Large trees cost memory and CPU on every visitor's device.

   Flatten wrapper markup, render long lists virtually or paginate, and prefer semantic elements over nested divs.

   WSG 3.6: Ensure code follows good semantic practices
