Quambio.

Context

Sustainable behavior needed visible feedback

Quambio encouraged people to choose lower-emission ways to move through a city, but the product value was hard to feel in the moment. CO2 savings are abstract, and abstract progress rarely changes a routine on its own.

The design challenge was to make walking, cycling, or choosing an electric scooter feel measurable, rewarding, and connected to a larger climate goal without turning the product into a dense environmental dashboard.

Challenges

Shared goals without heavy social pressure

Group challenges created shared momentum around environmental goals. The design kept the mechanic lightweight so it supported commitment without making the app feel like a social feed.

Challenges were useful because sustainable behavior often benefits from social context. The system let users participate, compare impact, and contribute to a shared climate goal while keeping the core task focused.

Reflection

What made the system stronger

The key move was treating sustainability as a product feedback problem. Once carbon savings became visible through a simple reward language, the product could connect daily movement to long-term motivation.

For portfolio representation, Quambio should lead with the cube metaphor and the action loop. The strongest case is not "we made a green app"; it is "we made invisible impact understandable enough to change behavior."
