People often lack awareness of how their daily travel choices contribute to their carbon footprint. Manual tracking of transportation and CO₂ emissions can be inconvenient and may not provide accurate or personalized insights. This makes it difficult for individuals to understand their environmental impact and make more sustainable choices. There is a need for an intelligent and user-friendly solution that can automatically identify travel patterns and estimate emissions while improving awareness. Carbonly addresses this gap by combining AI, GPS, smartwatch sensor data, and user input to track transportation-related emissions and provide personalized sustainability insights.
