At 10,000 views a month this page emits about 10.5 kg CO₂e a year, roughly 43 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 1%, and world-average grid intensity. How we calculate this

1. Audit third-party servicessave ~0.019 g/visit (170 kB)Medium impact · moderate effort

   11 third-party domains account for 340 kB (43% 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.

   • fonts.gstatic.com63 kB
   • s.go-mpulse.net59 kB
   • ajax.googleapis.com30 kB
   • canada.demdex.net3.4 kB
   • dpm.demdex.net917 B

2. Enable text compressionsave ~0.016 g/visit (142 kB)Medium impact · quick fix

   5 text resources (203 kB) are served without gzip/Brotli.

   Enable Brotli (or at least gzip) on the server or CDN for HTML, CSS, JavaScript, JSON and SVG. Typical reduction is ~70%.

3. Reduce JavaScript payloadsave ~0.011 g/visit (94 kB)Medium impact · moderate effort

   9 scripts total 377 kB on the wire (1.32 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.

4. 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.

5. Upgrade compression beyond gzipsave ~0.0073 g/visit (65 kB)Advisory · quick fix

   436 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.

   • jquery.min.js30 kB
   • theme.min.js22 kB

6. Remove the entry redirectAdvisory · quick fix

   The address that was scanned goes through 1 redirect before the document is served, ending at https://www.canada.ca/. 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.
