At 10,000 views a month this page emits about 28.0 kg CO₂e a year, roughly 115 km in an average petrol car. The estimate assumes 75% new and 25% returning visitors, a measured cache reload ratio of 3%, and world-average grid intensity. How we calculate this
What to fix
apply everything → ~0.104 g/visit, rating B
Convert and compress imagessave ~0.045 g/visit (490 kB)High impact · quick fix
12 images (1.09 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.
- hand-phone.png581 kB
- burnout.jpg93 kB
- digital.jpg83 kB
- t3.png82 kB
- remote.jpg71 kB
Lazy-load below-the-fold mediasave ~0.027 g/visit (295 kB)High impact · quick fix
3 below-the-fold images/iframes (589 kB) download immediately for every visitor.
Add loading="lazy" to below-fold img and iframe elements (and keep it off the LCP image). Browsers then fetch them only when scrolling approaches.

Optimize web fontssave ~0.038 g/visit (415 kB)Medium impact · quick fix
8 font files total 714 kB, 2 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.

Serve images at the size they displaysave ~0.011 g/visit (121 kB)Medium impact · quick fix
7 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.

Reduce JavaScript payloadsave ~0.0079 g/visit (86 kB)Medium impact · moderate effort
29 scripts total 343 kB on the wire (1.00 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.

Set a page-weight budgetAdvisory · moderate effort
At 2.54 MB per view this page rates D. 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.
Remove the entry redirectAdvisory · quick fix
The address that was scanned goes through 1 redirect before the document is served, ending at https://upcyman.com/en. 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.

Simplify the document structureAdvisory · larger effort
The page renders 1764 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.
