CABOCHA is a lifestyle app that focuses on calculating and reducing CO2 emissions. Users can determine their monthly CO2 emissions by answering 12 questions regarding factors like transportation frequency and dietary habits. The app categorizes emissions into six categories, such as housing, transportation, and food, providing a clear overview of where emissions are highest.

Additionally, CABOCHA offers around 100 actions to help reduce CO2 emissions, ranging from simple to more challenging tasks. Each action specifies its frequency and CO2 reduction amount, allowing users to choose easily actionable steps to implement.

Furthermore, the app features a ranking system based on CO2 reduction achievements, motivating users to aim for the top spot and continue their efforts towards a greener lifestyle.
