Inspiration

Urban living is the heartbeat of our future, but also where sustainability challenges are most pressing. We wanted to design a tool that makes carbon awareness fun, achievable, and relevant to everyday city life.

What it does

Terrago gamifies carbon footprint tracking for households.

Users input simple lifestyle details (cars, diet, solar, etc.).
The app calculates their estimated footprint.
It then suggests small, personalized actions (e.g., swap one car trip for a walk, try a veggie meal) that add up to meaningful urban impact.

How we built it

Frontend: Flutter for cross-platform speed and a clean mobile experience.
Backend: Go Fiber server + Supabase for quick auth and data storage.
Logic: A transparent carbon calculator built from fixed factors and pseudocode for consistency.
Design: Playful UI/UX and gamification elements to make sustainability engaging.

Challenges we ran into

Balancing simplicity with scientific accuracy in footprint calculations.
Integrating datasets (e.g., city emissions) without overwhelming users.
Hackathon crunch: merging design + code quickly while avoiding feature creep.

Accomplishments that we’re proud of

Built a functional end-to-end pipeline (input → carbon estimate → actionable steps).
Designed a gamified approach that makes climate action less intimidating.
Collaborated seamlessly across development, design, and research under 24h pressure.

What we learned

Gamification boosts engagement, even for “serious” topics like carbon emissions.
Small, achievable actions can be just as powerful as large-scale changes when scaled across communities.
Teamwork and rapid prototyping matter more than perfection in hackathons.

What’s next for Terrago

Hyperlocal insights: Incorporate open city datasets to tailor footprints by suburb.
Enhanced gamification: Add challenges, streaks, and community leaderboards.
Mobile pilot: Deploy Terrago on campus for live testing with students.
Partnerships: Collaborate with councils and sustainability groups to scale impact across urban communities.
