0.64g CO2 per page view
This page transfers 2.7 MB, producing an estimated 0.64g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.02g, network 0.13g, end-user device 0.49g.

Info::
At 10,000 monthly views: 76.9 kg CO2/year
With 10,000 page views per month, this page would generate approximately 76.9 kg of CO2 annually — equivalent to charging 9607 smartphones.

Web Font Weight Variants
No detectable Google Fonts weights
No detectable Google Fonts weights
Info::
No detectable Google Fonts weights
The analyzer detects font weights via Google Fonts URL parameters (~70% of font-using sites). Self-hosted fonts and non-Google CDN fonts aren't visible to URL-based detection. If you self-host fonts, manually audit how many @font-face weights you ship -- 2-3 weights per family is typically enough; 5+ is usually unused payload.
