At 10,000 views a month this page emits about 46.5 kg CO₂e a year, roughly 190 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 9%, and world-average grid intensity. How we calculate this

1. Audit third-party servicessave ~0.151 g/visit (1.32 MB)High impact · moderate effort

   48 third-party domains account for 2.64 MB (78% 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.

2. Convert and compress imagessave ~0.052 g/visit (452 kB)High impact · quick fix

   18 images (1.00 MB) ship in legacy formats (JPEG/PNG/GIF).

   Serve AVIF (or WebP) with responsive srcset sizes, and re-compress oversized files. AVIF typically halves JPEG weight at the same visual quality.

3. Reduce JavaScript payloadsave ~0.042 g/visit (363 kB)High impact · moderate effort

   33 scripts total 1.45 MB on the wire (5.03 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. Optimize web fontssave ~0.030 g/visit (264 kB)Medium impact · quick fix

   11 font files total 478 kB, 6 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.

5. Fix caching for returning visitorssave ~0.0092 g/visit (62 kB)Medium impact · quick fix

   On a repeat visit 248 kB of static assets were re-downloaded instead of coming from cache.

   Serve static assets with Cache-Control: public, max-age=31536000, immutable and versioned filenames so returning visitors download almost nothing.

6. 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.

   WSG 4.1: Use sustainable hosting
7. Upgrade compression beyond gzipsave ~0.017 g/visit (151 kB)Advisory · quick fix

   1.01 MB 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.

8. Remove references to broken resourcessave ~<0.001 g/visit (31 B)Advisory · quick fix

   1 request answered 4xx/5xx on load: transfer and connections spent on nothing, on every single visit.

   Delete or fix the references (stale asset URLs, dead third-party tags). Each one is a request the page provably does not need.

9. Set a page-weight budgetAdvisory · moderate effort

   At 3.38 MB per view this page rates F. 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
10. Remove the entry redirectAdvisory · quick fix

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

11. Simplify the document structureAdvisory · larger effort

    The page renders 13037 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.
