At 10,000 views a month this page emits about 35.9 kg CO₂e a year, roughly 147 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 5%, and world-average grid intensity. How we calculate this

1. Audit third-party servicessave ~0.024 g/visit (266 kB)High impact · moderate effort

   7 third-party domains account for 531 kB (16% 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.

   • client.axept.io3.4 kB
   • fonts.axept.io1.5 kB
   • api.axept.io353 B

   WSG 3.5: Treat third parties the same as first parties
2. Reduce JavaScript payloadsave ~0.019 g/visit (211 kB)High impact · moderate effort

   6 scripts total 843 kB on the wire (3.06 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.

   • layout.astro_astro_type_script_index_1_lang.C…313 kB
   • sdk.js200 kB
   • js190 kB
   • gtm.js128 kB
   • behavior-detection.min.js8.6 kB

   WSG 3.2: Minify and remove unused codeWSG 3.3: Modularize bandwidth-heavy components
3. Optimize web fontssave ~0.031 g/visit (336 kB)Medium impact · quick fix

   3 font files total 554 kB, 2 not in WOFF2.

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

   • Inter-VariableFont.ttf430 kB
   • ALTMistral-Medium.woff279 kB
   • SpaceMono-Regular.ttf45 kB

   WSG 2.11: Use optimized web typography
4. Serve images at the size they displaysave ~0.019 g/visit (209 kB)Medium impact · quick fix

   9 images are encoded at more than twice the pixels the layout shows, even accounting for this viewport's pixel density.

   Generate multiple sizes and let the browser pick with srcset/sizes; a 4000px original behind a 400px slot spends bandwidth no screen displays.

   WSG 2.9: Optimize media to reduce resource use
5. Set a page-weight budgetAdvisory · moderate effort

   At 3.25 MB per view this page rates E. 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.

   WSG 3.1: Set goals based on performance and energy impact
6. Simplify the document structureAdvisory · larger effort

   The page renders 3476 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
