At 10,000 views a month this page emits about 19.9 kg CO₂e a year, roughly 81 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 0%, and world-average grid intensity. How we calculate this

  1. Serve images at the size they displaysave ~0.046 g/visit (412 kB)High impact · quick fix

    12 images are encoded at more than twice the pixels the layout shows, even accounting for this viewport's pixel density.

    Generate multiple sizes and let the browser pick with srcset/sizes; a 4000px original behind a 400px slot spends bandwidth no screen displays.

  2. Audit third-party servicessave ~0.022 g/visit (199 kB)Medium impact · moderate effort

    5 third-party domains account for 397 kB (27% 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.

  3. Reduce JavaScript payloadsave ~0.014 g/visit (127 kB)Medium impact · moderate effort

    28 scripts total 509 kB on the wire (1.61 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. Remove the entry redirectAdvisory · quick fix

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