An interactive climate-tech web application that audits the carbon footprint of a product’s entire supply chain.
Green-Wash Verifier helps identify misleading sustainability claims (“greenwashing”) by quantifying hidden emissions across logistics routes and comparing them with cleaner alternatives.
Instead of only measuring emissions at the factory, this system evaluates the full journey of a product — from raw material source to final retailer — using real-world transport emission factors. This turns sustainability into a measurable, auditable, and explainable metric, not just a marketing claim.
- 🌍 Multi-leg Supply Chain Modelling: Simulate real-world logistics: Source → Factory → Port → Retailer.
- 📊 Live Carbon Auditing Dashboard: Instantly updates emissions as users change routes and transport modes.
- 🔍 Greenwashing Detection: Compares actual routes against optimal low-carbon routes.
- 📈 Explainable Visual Analytics: Bar charts and tables show exactly where emissions occur.
- 💡 What-If Sustainability Simulator: Calculates CO₂ savings from cleaner logistics decisions.
The system is built using a clean, professional architecture:
| Layer | File | Purpose |
|---|---|---|
| Logic Engine | engine.py |
Performs carbon calculations using emission factors |
| Web Interface | app.py |
Interactive dashboard built with Streamlit |
| Visualization | Plotly |
Displays emissions by supply-chain leg |
For each transport leg:
Carbon Emissions = Weight × Distance × Emission Factor
The total product footprint is the sum of all legs.
- Python - Core logic and calculations
- Streamlit - Interactive Web UI
- NetworkX - Supply chain graph modelling
- Plotly - Interactive charts & visualizations
- Pandas - Data handling & manipulation

Many companies claim products are “eco-friendly” while ignoring emissions from global shipping and logistics. This project exposes that blind spot by making supply-chain pollution visible, measurable, and comparable.
