At 10,000 views a month this page emits about 0.3 kg CO₂e a year, roughly 1 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 4%, and world-average grid intensity. How we calculate this

What to fix

  1. Audit third-party servicessave ~<0.001 g/visit (5.9 kB)Medium impact · moderate effort

    2 third-party domains account for 12 kB (48% 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.
