EcoMark – A Simple Way to Reflect on Our Carbon Footprint
What I Built
For this challenge, I built EcoMark, a lightweight web app that helps people quickly understand their everyday environmental impact.
The idea was simple:
Most of us care about the planet, but we don’t always know how our daily habits translate into real impact.
EcoMark bridges that gap by turning a few lifestyle choices into a clear, understandable carbon score, along with practical suggestions for improvement.
Users answer a few short questions about:
- How they get around
- What they eat
- Their energy usage
- Their shopping habits
Based on this, the app calculates a score and places them into a category:
- Green Hero
- Improving
- High Impact
To make it more useful (and less judgmental), the app also generates personalized tips to help users reduce their footprint in realistic ways.

Code
The project was built and deployed using:
- JavaScript
- HTML/CSS
- Google Gemini API
- Replit (development + hosting)
How I Built It
I approached this project with a focus on simplicity, clarity, and usability, especially since many users might access it on mobile devices.
1. Carbon Scoring Logic
Instead of trying to build a scientifically perfect calculator, I designed a simple scoring system that reflects relative impact:
- Higher-emission activities (e.g., frequent car use, meat-heavy diets) increase the score
- Lower-impact choices (walking, plant-based diets) reduce it
This keeps the experience intuitive while still meaningful.
2. Backend with JavaScript
I used JavaScript to:
- Handle form input
- Process user responses
- Calculate the carbon score
- Render results dynamically
3. AI-Powered Suggestions with Google Gemini
One of the most interesting parts of this project was integrating the Google Gemini API.
Instead of hardcoding advice, I generate tips dynamically based on the user’s score.
- Higher scores → stronger, more impactful suggestions
- Lower scores → reinforcement of good habits
This made the app feel more:
- Personalized
- Engaging
- Practical
4. Building with Replit
Since I didn’t have access to a full development setup, I built everything directly in Replit.
This influenced my approach:
- Keeping the architecture simple
- Avoiding unnecessary dependencies
- Prioritizing fast iteration
It turned out to be a great way to go from idea → working product quickly.
5. Design Choices
I intentionally kept the UI:
- Clean
- Minimal
- Mobile-friendly
The goal was to make the experience feel approachable rather than overwhelming.
What I Learned
This project reminded me that:
- You don’t need complex systems to communicate important ideas
- AI works best when it enhances—not replaces—core logic
- Constraints can lead to better, more focused solutions
Future Improvements
If I had more time, I’d love to:
- Add location-based recommendations
- Improve scoring accuracy
- Include visual progress tracking
- Let users compare lifestyle scenarios
Final Thoughts
EcoMark isn’t meant to be a perfect measurement tool.
It’s a conversation starter—a small way to help people reflect on their habits and take simple steps toward a more sustainable lifestyle.
Small changes, multiplied by many people, can make a real difference.
Thanks for reading! 🌱
