The Sustainable UX Canvas

On OLED screens, darker colors use less energy, enabling Dark Mode by default can reduce power consumption and support sustainable design.

Images impact energy use; optimize with efficient formats, compression, Lazy Loading, and responsive delivery to cut CO₂ emissions.

Fonts impact energy efficiency — system fonts reduce data consumption and improve performance, while limiting web font variations minimizes unnecessary downloads.

Streaming, videos, and 3D elements increase energy use — optimize formats, avoid autoplay, and offer lower-resolution options to reduce digital impact.

A transparent UI shows users the CO2 impact of their choices; empowering them to make more sustainable decisions in real time.

Let users control sustainability features, from loading media to email preferences, to avoid forced green choices and ensure flexibility.

Caching stores frequently used data locally to reduce server requests and speed up load times, while local storage keeps data longer on the user’s device to avoid repeated requests.

An updated CMS improves efficiency and reduces resource use by removing unnecessary plugins, cleaning inactive content, and implementing proper caching.

Unnecessarily large files increase load times and resource use. Compressing, minifying, bundling, and regularly reviewing HTML, CSS, and JavaScript reduces file sizes, HTTP requests, and improves performance.

Server choices impact sustainability as data centers consume vast energy; using green hosting, optimizing server usage, and monitoring performance reduces a website’s carbon footprint.

Lazy Loading ensures that images and videos load only when they become visible to the user, saving data and energy.

Fewer server requests improve site speed and energy efficiency by bundling CSS and JavaScript, using sprites to consolidate images, and leveraging CDNs to deliver content closer to users.

An efficient search with clear navigation and precise results reduces unnecessary browsing, server load, and time spent clicking through pages.

Videos and animations are energy-intensive; use adaptive streaming, disable autoplay, and choose efficient formats like AV1 or VP9 to reduce impact.

Have you considered how accessibility and inclusive design can ensure all users, regardless of ability, can navigate and interact with your digital solution?

Have you considered how infinite scrolling, autoplay, and constant notifications drive excessive digital consumption, wasting data and energy?

Have you considered how AI, cultural context, and inclusive design choices can impact equity, fairness, and equal access for all users?

Have you considered how your UX design choices can influence behavior—either by empowering users ethically or manipulating them through deceptive patterns?
