At 10,000 views a month this page emits about 2.6 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 10%, and world-average grid intensity. How we calculate this
What to fix
apply everything → ~0.010 g/visit, rating A+
Audit third-party servicessave ~0.0097 g/visit (84 kB)Medium impact · moderate effort
1 third-party domain account for 168 kB (90% 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.
- s.yimg.com168 kB
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.
Collapse the redirect chainMedium impact · quick fix
The address that was scanned goes through 3 redirects before the document is served, ending at https://consent.yahoo.com/v2/collectConsent?sessionId=3_cc-session_dbd5380e-33fd-43a6-bec1-b1e2786c46dc. Every hop is a full round trip on a connection that has not warmed up yet.
Point links, sitemaps and canonical tags at the final address, and make the host redirect in one hop rather than chaining http to https to www.

Upgrade compression beyond gzipsave ~0.0018 g/visit (16 kB)Advisory · quick fix
106 kB of text ships gzip-compressed; Brotli or Zstandard would cut roughly another 15-20%, and browsers without them fall back to gzip automatically.
Serve precompressed Brotli for static text assets (highest level, compressed at build time) and enable Brotli or zstd for dynamic responses; keep gzip only as the fallback.
