Inspiration

Climate tools often overwhelm people with abstract numbers like “tons of CO₂,” which most users don’t understand or act on. We wanted to create something simple, human, and motivating — a way for people to understand their sustainability habits the same way they understand a credit score. GreenScore was inspired by one question: What if sustainability were as easy to track and improve as your credit score?

What it does

GreenScore is a web app that gives users a 0–100 sustainability score based on everyday lifestyle choices such as transportation, energy use, food habits, and waste management. Instead of just showing a score, GreenScore:

Breaks down where the score comes from
Highlights which habits have the biggest impact
Shows how small changes can immediately improve the score The goal is to turn awareness into actionable behavior change.

How we built it

GreenScore was built as a lightweight web application with:

React / Next.js for the frontend
Tailwind CSS for a clean, modern UI
A transparent, rule-based scoring engine The scoring logic is intentionally simple and explainable, focusing on education rather than scientific precision.

Challenges we ran into

I didn't run into any major challenge building this project just minor bugs here and there which i fixed successfully

Accomplishments that i'm proud of

Creating a sustainability tool that is easy to understand in under a minute
Designing a scoring system that clearly explains why a score changes
Building a complete, demo-ready product as a solo project
Turning sustainability concepts into something interactive and engaging

What i learned

I learned that how information is presented matters as much as the information itself. Users are more likely to care when sustainability feels personal, measurable, and achievable.

I also learned that simple, honest tools can be more impactful than complex systems that users don’t trust or understand.
