Vehicle Carbon Footprint
Estimate your vehicle's annual CO₂ emissions based on mileage, fuel type, and efficiency.
Annual CO₂ Emissions
🌍 Your Emissions vs Average
🌳 Carbon Offsets
Trees Needed to Offset
219 mature trees per year
One mature tree absorbs ~21.77 kg CO₂ per year
💡 Reduce Your Carbon Footprint
- • Carpool or use public transportation
- • Switch to an electric vehicle
- • Maintain proper tire pressure and vehicle maintenance
- • Combine trips and plan efficient routes
- • Consider a hybrid vehicle
- • Drive smoothly (avoid rapid acceleration)
Formula
CO₂ (kg) = Fuel Used (gallons) × Emission Factor (kg CO₂/gallon)
Gasoline: 8.887 kg CO₂/gallon | Diesel: 10.155 kg CO₂/gallon
How it works
CO₂ (kg) = Fuel Used (L) × Emission Factor (kg CO₂/L) Emission Factors (per gallon): Gasoline: 8.887 kg CO₂ Diesel: 10.155 kg CO₂ Hybrid: 4.444 kg CO₂ (50% reduction) Electric: 0.02 kg CO₂ per mile (grid average) Example: 15,000 miles/year ÷ 28 mpg = 536 gallons 536 gallons × 8.887 kg/gallon = 4,763 kg CO₂/year US Average Vehicle: ~4,600 kg CO₂/year One mature tree offsets: ~21.77 kg CO₂/year
The vehicle carbon footprint calculator estimates your car's annual CO₂ emissions based on mileage and fuel type. Enter annual mileage or fuel used to calculate total emissions, monthly breakdown, and how many trees are needed to offset. Compare your emissions to the average vehicle and get tips for reducing your carbon footprint.
Why this matters
Transportation is a major source of greenhouse gas emissions. Understanding your vehicle's carbon footprint helps you make eco-friendly choices. Switching to electric or hybrid vehicles, carpooling, and reducing unnecessary driving can significantly reduce emissions. Your individual impact matters—collective action creates environmental change.
