UXGreen™ — Sustainable Digital Efficiency Certification | MediaLab

The real problem

Why does bad UX pollute the web?

A slow site doesn't just frustrate your users — it consumes more energy, generates more CO₂, requires more infrastructure, and destroys more business. Digital inefficiency has a double cost: human and environmental.

The UXGreen™ equation

Optimal performance=Less energy=Better UX=More conversion=Lower CO₂

The standard

8 dimensions of the MediaLab digital efficiency standard

UXGreen™ evaluates what matters: the real experience, environmental impact, and readiness for the future of the web.

Energy consumption

Speed, Google metrics, and carbon footprint per visit

Performance

01

Speed is respect

Every 100ms improvement in load time reduces bounce rates by 8% and energy consumption per session. Speed is not a luxury — it's efficiency.

53%

of users leave if load time > 3s

Core Web Vitals

02

The standards Google measures

LCP, CLS, and TBT are the signals Google uses to determine your ranking. Good CWV also means a more energy-efficient site.

1.5s

Ideal LCP per UXGreen™ standard

Carbon Efficiency

03

Every byte has a real weight

The global web generates more annual CO₂ than the airline industry. An optimized site can be up to 80% cleaner than average.

0.5g

CO₂ per visit on optimized sites

Resource efficiency

Fewer server requests, fewer reloads, less energy wasted by poor UX

UX Efficiency

04

Fewer clicks, less energy

Every unnecessary click is an extra server request that consumes energy. An efficient flow reduces HTTP requests, processing time, and energy expenditure per session.

40%

fewer requests with optimized flows

Accessibility

05

Inclusion that reduces waste

An inaccessible site forces 15% of users to retry, reload, and abandon — generating unnecessary traffic and processing. WCAG 2.2 isn't just legal: it reduces bounce rates and energy consumption from failed visits.

15%

of users generate extra traffic due to barriers

Cognitive Load

07

Confusion = more consumption

A confusing interface generates reloads, repeated clicks, and longer sessions — every unnecessary action consumes CPU, bandwidth, and server energy. Reducing cognitive load means reducing the carbon footprint.

to decide if your UI wastes energy

Long-term sustainability

Efficient AI and sustainable design that reduces energy cost with every iteration

AI Efficiency

06

AI that indexes, not consumes

LLMs consume massive energy per query. Well-structured content reduces the inferences needed and improves citability.

3×

more citable with semantic architecture

Sustainable UX

08

Design that lasts and matters

Digital sustainability measures the ratio between digital resources consumed and real value delivered. A new KPI for a new era.

of the web can improve this ratio
