What it does💡 Inspiration

A growing global concern about environmental sustainability inspired us to create CarboTrack — a platform that empowers individuals to understand and actively reduce their carbon footprint. Every action we take — from daily travel to online shopping — contributes to carbon emissions. However, most people don’t know how much they produce or how to offset it. CarboTrack bridges this gap through AI-powered insights and real-time carbon tracking, transforming awareness into meaningful action.

⚙️ How We Built It

CarboTrack was built with a robust and modern tech stack designed for performance, scalability, and innovation:

Frontend: React.js for a smooth, responsive user experience.

Backend: Node.js and Express for efficient API handling.

Database: MongoDB for dynamic and flexible data storage.

Blockchain Integration: IPFS for secure and decentralized bill and data storage.

AI Integration: Generative AI (LLM) and OCR models to analyze user data, extract carbon metrics, and generate personalized insights.

Mathematically, the system computes each user’s estimated footprint using simplified models of CO₂ emissions:

𝐶

∑

𝑖

1 𝑛 ( 𝐸 𝑖 × 𝐹 𝑖 ) C= i=1 ∑ n ​

(E i ​

×F i ​

)

where 𝐸 𝑖 E i ​

is the energy or activity unit, and 𝐹 𝑖 F i ​

is its carbon conversion factor.

🚀 Features Implemented

We successfully integrated seven major features into CarboTrack:

🏠 Energy Usage Tracker – Monitors daily energy consumption patterns.

🌿 Carbon Footprint Calculator – Uses OCR and AI to simplify carbon analysis.

🚗 Community Carpooling Hub – Connects users for shared rides to reduce emissions.

📰 Eco News Feed – Keeps users informed with the latest sustainability articles.

🗺️ Sustainable Route Planner – Suggests eco-friendly travel options.

🔐 Secure Bill Storage (IPFS) – Decentralized bill management for transparency.

🛒 Chrome Extension – Instantly checks product CO₂ impact while shopping online.

🧠 What We Learned

Through this project, we explored the power of combining AI and blockchain for social impact. We learned:

How to integrate LLMs for contextual sustainability advice.

Techniques for OCR data extraction and its preprocessing pipeline.

Best practices for performance optimization in feature-heavy web apps.

How small behavioral nudges can make a large-scale climate difference.

🧩 Challenges We Faced

Building CarboTrack was both exciting and technically demanding. Some challenges included:

Synchronizing multiple data sources in real-time without performance drops.

Ensuring data privacy while using blockchain storage.

Implementing AI interpretability, so users understand how insights are generated.

Balancing UI/UX simplicity with the complexity of sustainability analytics.

🏆 Outcome & Impact

CarboTrack transforms sustainability from a distant goal into an accessible, everyday practice. By combining technology, data, and behavioral science, we help individuals measure, reduce, and reward their eco-conscious actions — one footprint at a time.
