I can’t change the world by myself. This is a common thought citizens share when it comes to climate action. Climate change campaigns usually aim at raising awareness and triggering action to reduce our footprint. However, these campaigns often fail as they are designed in a top-down manner. The ChallengeYeti app was created on a psychological-technological foundation focusing on motivational and bottom-up approaches to bridge this knowledge-action gap. Hence, the app primarily strives to trigger behavioral change in a fun and social way. This paper introduced the app and its functionalities, its theoretical and technical background, its implementation, its expected impact on behavioral change, and lastly, future challenges of the app.

Citizen science is a valuable tool to inculcate awareness among citizens about climate change issues. This is also the main goal of the I-CHANGE project. On these lines, Hasselt living lab as part of the I-CHANGE project developed a collaboration with a technical secondary school. Digital sensors such as Meteotrackers and smart citizen kits will be utilized under this collaboration where students and teachers will not only collect data, but will be using it in an innovative manner to integrate the findings obtained from its analysis to enhance students learning about climate change issues. This paper presents a structured methodological approach to achieve this goal.
