W3C Web Sustainability Guidelines (WSG) · Digital Carbon Footprint
The average webpage emits more CO₂ per visit than it needs to, by a wide margin.
I audit and rebuild digital products against the W3C Web Sustainability Guidelines — cutting page weight, hosting emissions, and wasted compute, without making the product feel like a compromise.
Why it matters
Most of a page's footprint isn't inherent to what it does — it's unoptimized images, third-party scripts nobody removed, and hosting chosen without emissions in mind. That's fixable, and it's usually cheaper to run once fixed.
~60%
of a typical page's weight is images/video that can usually be halved with no visible quality loss
1–2%
of global electricity use is estimated to go to data centres and networks serving the web

trade-offs required on brand or usability when sustainability is designed in, not bolted on
What this means here
Aligned to the W3C Web Sustainability Guidelines, not a green badge.
Lean by default
Right-sized images and no dependency shipped that isn't earning its weight.
Green hosting, verified
Matching your infrastructure against renewably-powered providers and CDN configs.
Efficient by architecture
Caching and render strategy chosen so the experience costs less compute per visit at scale.
Accountable, not just labeled
Every recommendation ties to a measurable before/after number for your sustainability report.
