WHY THIS FOOTPRINT IS LOW
◆
Zero images — SVG only All visuals are inline SVG. No raster images, no lazy-load overhead, no CDN image pipeline.
◆
Static hosting on CDN Served from Netlify's global CDN. No server-side processing, no database queries, no compute on each request.
◆
Minimal JavaScript Under 5 KB of JS. No frameworks, no bundlers, no runtime overhead. Vanilla JS for nav and scroll reveal only.
◆
No tracking or analytics scripts Zero third-party tracking. No Google Analytics, no pixels, no tag managers. Your visit generates data transfer — nothing else.
◆
System font fallbacks Three Google Fonts families are loaded (Space Grotesk, IBM Plex Sans, IBM Plex Mono) with system fallbacks. Font files are the largest transfer cost.
◆
Aggressive caching CSS, JS, and fonts are cached with immutable headers. Return visits transfer near-zero data — only the HTML document.

Methodology

HOW WE CALCULATE

All figures on this page are calculated in real-time using the Sustainable Web Design (SWD) model and the browser's Performance API.

The SWD model estimates energy consumption based on actual data transferred per page view. We measure bytes transferred using PerformanceResourceTiming, then apply the model's energy intensity factor and global grid carbon intensity to produce a CO₂ estimate.

No data is sent to external servers. All calculations run locally in your browser. Session data is stored in sessionStorage and cleared when you close the tab.

SWD MODEL / CALCULATION
01 Data = transferSize from Performance API
02 Energy = Data (GB) × 0.81 kWh/GB
03 CO₂ = Energy × 442 g/kWh (global grid avg)
04 Green hosting adjustment: −9% (CDN renewable mix)
