AI Carbon Footprint Calculator - Predict Your CO2 Emissions Using Machine Learning

Personal Carbon Footprint Prediction Using Machine Learning

Most people have no real idea how much carbon dioxide their daily habits produce. They might know that driving pollutes more than cycling, but when it comes to putting a number on their grocery shopping, shower frequency, or screen time, things get vague fast. This project changes that. It takes roughly 20 lifestyle inputs from a user, runs them through a trained machine learning model, and returns a concrete annual CO2 estimate in kilograms, along with a full breakdown of where that carbon is actually coming from.

Machine Learning Model and Dataset

The prediction engine sits on two algorithms: Random Forest and XGBoost. Both were trained on the Individual Carbon Footprint Calculation dataset from Kaggle, which includes thousands of records covering body type, diet, transport habits, energy sources, waste generation, digital usage, and more.

The raw dataset needed cleanup before it was usable. Columns like Recycling and Cooking_With stored Python list strings that had to be parsed and one-hot encoded. Vehicle Type had blanks for people who walk or take public transport, which required explicit handling. The complete preprocessing, feature engineering, model training, and evaluation pipeline is available inside a Jupyter Notebook so students can understand every step of the workflow.

Streamlit Dashboard

After training, the models are exported as pickle files and loaded into a Streamlit web application. The application contains five organized input sections:

• Personal: Body type, gender, and diet.
• Home: Shower habits, heating source, cooking methods, and energy efficiency.
• Transport: Transportation mode, vehicle type, and monthly travel distance.
• Lifestyle: Social activity, grocery spending, clothing purchases, and air travel.
• Digital & Waste: Screen time, internet usage, waste generation, and recycling habits.

Once the user submits the form, the application predicts the annual carbon footprint, assigns an environmental grade from A to F, categorizes the user using KMeans clustering into groups such as Eco Warrior, Green Beginner, Average Consumer, or High Emitter, and compares the result with the dataset average.

Interactive Analytics Dashboard

Carbon Emission Breakdown

The first dashboard tab displays a Plotly donut chart that separates emissions into transport, home energy, diet, shopping, digital usage, and waste, making it easy to identify the largest contributors.

Country Comparison

The second tab compares the predicted footprint with average emissions from India, the USA, the UK, China, Germany, Brazil, Japan, and the global average, allowing users to benchmark their lifestyle.

What-If Lifestyle Simulator

The third tab lets users simulate lifestyle changes such as switching to a vegetarian diet, reducing flights, or using public transport. The dashboard instantly recalculates the estimated annual carbon savings.

Carbon Gauge Meter

The final dashboard tab includes a color-coded gauge chart that places the user's emissions on a 0–20,000 kg CO₂ scale using green, yellow, orange, and red zones for quick interpretation.

Recommendation and Carbon Offset Engine

Personalized Recommendations

The recommendation engine analyzes user inputs and provides a prioritized list of actionable improvements. Every recommendation includes an estimated annual CO₂ reduction, helping users understand the environmental impact of each change.

Carbon Offset Calculator

The project converts total emissions into real-world equivalents such as:

• Number of trees required to offset emissions.
• Equivalent solar panels needed.
• Estimated car-free days required to compensate for the footprint.

PDF Report Generation

Using FPDF2, the application generates a professional PDF report containing the user's predicted emissions, environmental grade, complete input summary, emission breakdown, personalized recommendations, estimated savings, and carbon offset calculations. This report can be submitted as part of academic documentation or project demonstrations.
