Audit third-party servicessave ~0.041 g/visit (370 kB)High impact · moderate effort
15 third-party domains account for 740 kB (44% 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.

26 scripts total 1.23 MB on the wire (3.74 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.

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.
Optimize web fontssave ~0.0047 g/visit (42 kB)Advisory · quick fix
2 font files total 120 kB.
Subset fonts to used glyphs, prefer one variable font over multiple weights, serve WOFF2 only, and consider system fonts for UI text.
