This project was aimed at kids and teenagers for an interactive workshop, designed to introduce them to the intertwined concepts of digitalization and sustainability in a fun and engaging way. To make this complex subject easier to understand, we utilized relatable analogies, drawing upon Crowther Lab's comprehensive research, to accurately depict the environmental consequences. The core idea of our tool is straightforward: Users input their daily hours on various apps, and our application estimates the annual CO2 emissions generated. These emissions are then equated to the number of trees required to offset this carbon footprint, emphasizing the age factor, since older trees are more effective in carbon absorption. Additionally, a unique feature allows users to modify the tree age, underscoring the importance of not just planting new trees, but preserving and safeguarding our existing forests. By displaying a clear and prominent CO2 score, we hope to spark conversations among peers as they compare their digital carbon footprints. The design aesthetics are a nod to the early days of digitalization, bridging the subject matter and the visual style.
