At 10,000 views a month this page emits about 16.5 kg CO₂e a year, roughly 68 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 → ~0.059 g/visit, rating A

  1. Reduce JavaScript payloadsave ~0.031 g/visit (328 kB)High impact · moderate effort

    54 scripts total 1.31 MB on the wire (4.32 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.

  2. Audit third-party servicessave ~0.029 g/visit (306 kB)High impact · moderate effort

    14 third-party domains account for 612 kB (42% 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.

    WSG 3.5: Treat third parties the same as first parties
  3. Fix caching for returning visitorssave ~0.0034 g/visit (28 kB)Medium impact · quick fix

    On a repeat visit 111 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.

    WSG 4.2: Optimize caching and support offline access
  4. Upgrade compression beyond gzipsave ~0.016 g/visit (172 kB)Advisory · quick fix

    1.15 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.

  5. Remove references to broken resourcessave ~0.0019 g/visit (21 kB)Advisory · quick fix

    4 requests 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.

  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.producthunt.com/. 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.
