This project was developed as part of a Hackathon focused on climate action. Our team of five had 48 hours to design, develop, and present an initiative aimed at improving environmental impact. On our own initiative, we also attended an ecology fair, where we spoke with several independent exhibitors to gather their feedback and enrich our concept. We are proud to have won the Best Idea Award.

Our concept is a small-scale social network where users can add friends and create or take on eco-friendly challenges. These challenges involve adopting sustainable habits, such as using a reusable bottle or a bamboo toothbrush, or participating in events like clean walks. When a challenge is accepted, friends can confirm the user’s honesty. Each day after acceptance, the user’s score increases, earning them ranks such as Bronze, Silver, Gold, or Diamond — encouraging friendly competition and mutual motivation.

The platform also allows users to take on shared challenges, such as carpooling, to promote teamwork and collective action.

One of the key features of our project is its partnership system. To keep users motivated, rewards are granted when certain scores or challenges are achieved — for example, discount codes for eco-friendly products, day trips, and many other perks.
