Carbon Footprint Calculator

How It Works

This calculator estimates your annual greenhouse gas emissions in metric tons of carbon dioxide equivalent (t CO2e).

• Travel: Combines vehicle mileage (~0.404 kg CO2e per mile) and commercial flight hours (~180 kg CO2e per hour with radiative forcing).
• Home Energy: Calculates annual household electricity emissions using national grid averages (~0.39 kg CO2e per kWh).
• Diet: Estimates baseline nutritional emissions from heavy meat consumption down to plant-based diets based on life-cycle research.
