Sustainable UX: Why sustainable digital experiences are the future

Imagine if every website you visited was like a flight journey: some are efficient and consume minimal energy, while others waste resources with unnecessary detours, excess baggage and stopovers. The digital world is no different – websites, apps and software contribute to CO₂ emissions, consume energy and leave an environmental footprint that is often overlooked. But with sustainable UX strategies, businesses can minimise their digital footprint while simultaneously boosting their success. This article explores how that works.

Why should this matter to you?

Your products are known for their precision and longevity. Wouldn’t it make sense for your digital presence to reflect these same values? By implementing sustainable UX, you can position your brand as innovative and forward-thinking while making a tangible contribution to reducing emissions.

The benefits of sustainable UX for your business

  • Cost savings: Efficient websites and apps that are optimised for media and code use less server power, lower hosting costs and reduce energy consumption.
  • Higher conversion rates: Research shows that every extra second of loading time can reduce conversion rates by up to 20%. Sustainable UX design and development improve loading times, ensuring customers stay engaged and convert.
  • Improved brand image: Authentic sustainability efforts – not just greenwashing – build trust with customers and attract top talent. A study by Facit Research found that sustainability strengthens brand image, increases willingness to purchase and fosters customer loyalty. It also aids recruitment efforts and employee satisfaction.
  • Regulatory compliance: ESG (Environmental, Social, Governance) standards are becoming mandatory. Sustainable digital solutions help businesses avoid penalties and market barriers. Companies with demonstrable sustainability practices may also benefit from lower interest rates on loans due to reduced financial risk.

Sustainability starts with user guidance

  • Set sustainability goals early on: Define UX objectives in the planning phase to enhance efficiency and minimise resource use.
  • Optimised user guidance: Reduce unnecessary clicks and streamline navigation to lower energy consumption.
  • Efficient information architecture: A well-structured, shallow hierarchy minimises unnecessary data requests.

Designing for efficiency

  • Dark mode palettes: OLED screens consume less energy with dark themes.
  • Reduced animations: Lower CPU and GPU load with energy-efficient content.
  • Reusable UI components: Design systems reduce development time and maintenance costs.

Technical optimisation for sustainable performance

  • Code minimisation: Less code means shorter processing times and lower storage demands.
  • Lazy loading: Load resources only when necessary to save bandwidth.
  • Reduced server requests: Caching and request bundling improve performance.
  • Minimal third-party scripts: Use external tracking and ad scripts selectively.

Using resources responsibly

  • Data cleaning: Regularly remove outdated data to reduce storage needs.
  • CO₂ tracking for marketing: Use tools to measure the digital energy footprint.
  • Edge analytics: Processing data on devices reduces server load and energy use.

Giving users the choice

When it comes to sustainable user experience, designers and commissioning parties bear responsibility. However, with a customisable eco view, users can have a say in how resource-friendly they want to consume a website. This can be done in a playful, interactive way with various settings for adjusting data volume, energy consumption and visual complexity.

Selectable design options for users could look something like this:

  1. Standard: full colours, images/videos are displayed automatically and all features are available
  2. Energy and data-saving: compressed images, no videos, reduced animations and image content in greyscale ensure lower energy consumption of OLED displays
  3. Minimal mode: content is only available in text form; the absence of images and a visual layout reduce loading times and CO₂ emissions

An example of this is the online magazine ‘Branch’: the website changes its design depending on the amount of fossil fuels in the network. This means it always stays within a defined carbon budget. Website visitors can also choose for themselves whether they want to display images or just read the image descriptions.
