A transparent UI provides users with clear insight into how their digital choices impact the environment. By displaying CO2 emissions for different delivery methods in an online store or showing energy consumption for various video quality options in a streaming service, users become more aware and empowered to make sustainable decisions.

Recommendations:

• Make consequences visible: Present concrete data on CO2 emissions, so users can see the difference between options.
  • Example: An online store could display at checkout: » Express delivery (1 day)=2 kg CO2 » Standard delivery (3 days)=1 kg CO2, When users directly see the climate impact of their choices, they are more likely to make environmentally friendly decisions.
• Continuous evaluation: Monitor how users respond to transparency efforts and refine the design accordingly. If few users choose a greener option, highlight the benefits more clearly to encourage sustainable choices.
