At 10,000 views a month this page emits about 6.1 kg CO₂e a year, roughly 25 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. Convert and compress imagessave ~0.022 g/visit (197 kB)Medium impact · quick fix

    13 images (437 kB) 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.

  2. 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.
