Visualization of an Individual Carbon Footprint Mitigation Plan Using Transaction Data

Sammanfattning: Achieving the objectives of the Paris Agreements requires actions being taken on different fronts. This study looked into how to visualize a carbon footprint mitigation plan for individuals. The research consisted of designing and implementing a prototype containing visualization of a mitigation plan in the Swedish mobile app DO, a newer type of carbon calculator that uses transaction data to estimate the users' carbon footprints. A user study was then conducted with app users to evaluate the visualization. Findings from the study involved that proper handling of data is important for what a mitigation plan communicates to the user, but that receiving guidance on how to proceed ahead was greatly appreciated regardless. For future research, the visualization of a mitigation plan on small screens could be developed further with the prototype developed for this study as a starting point. It was suggested that such research could revolve around interaction improvements, evaluation with more frequent users, and observing whether a mitigation plan could affect behavior change.
