Codos Foundation, a non-profit organisation based in Zug, Switzerland, is poised to introduce an innovative solution to address the constraints and challenges that impede individuals from engaging in climate-conscious behaviours, which is a mobile application designed to calculate the amount of carbon dioxide (CO2) emissions avoided when people use eco-friendly transportation methods. This thesis aims to assist Codos Foundation in evaluating FHNW trial field viability by studying student motivations for Codos app use and trial participation, aiding successful implementation at FHNW university.

To explore Codos' potential in establishing a testing field at FHNW, three methods are employed. Secondary research gauges Swiss youth interest in sustainable transport, laying a foundation for assessing Codos' relevance. Additionally, 20 FHNW students' viewpoints on the Codos app and testing field are gathered through focus groups. Expert lecturers are also interviewed for relevant insights. By collecting detailed suggestions from students and lecturers for establishing a testing field at FHNW, the team hopes to gain useful insights that will help Codos Foundations' trial run succeed.

Results indicate a positive inclination towards environmentally friendly actions among FHNW students, aligning with broader Swiss youth behaviours. Factors influencing students' interest in the Codos app and testing project are analyzed using the Theory of Planned Behaviour model. "Subjective norms" minimally impacted students, while "attitudes" significantly influenced intentions. Students were impressed with the app's purpose but expressed concerns about its mechanics and data privacy. "Perceived behavioral control" issues such as flexible location and timing, as well as simplicity in the testing processes, affected the students' commitment to the project. The study creates a framework to understand sustainable behaviors in FHNW students and identifies factors influencing their Codos app usage and trial run participation. This informs Codos' strategy and provides guidance for similar apps. The insights from students and lecturers help Codos enhance its practical recommendations for establishing a testing field at FHNW. Although focused on FHNW, the findings also serve as a foundation to promote sustainability among Swiss students, fostering environmental awareness and engagement
