About Fuel Consumption & Environmental Impact

Understanding the relationship between fuel consumption, cost, and environmental impact can help make more sustainable transportation choices.

Fuel Efficiency

Fuel efficiency measures how far a vehicle can travel using a specific amount of fuel.

  • MPG (Miles Per Gallon): Common in the United States
  • L/100km (Liters per 100 kilometers): Common in Europe and most other countries
  • km/L (Kilometers per Liter): Used in some countries
Carbon Emissions

Burning fossil fuels releases carbon dioxide (CO₂) and other greenhouse gases that contribute to climate change.

  • Gasoline: Approximately 8.87 kg of CO₂ per gallon
  • Diesel: Approximately 10.16 kg of CO₂ per gallon
  • Electric: Emissions vary based on electricity source
Eco-Driving Techniques

Small changes in driving behavior can significantly reduce fuel consumption and emissions:

  • Maintain Steady Speed: Avoid rapid acceleration and braking
  • Optimal Speed: Fuel efficiency typically peaks at 45-55 mph
  • Reduce Idling: Turn off the engine when stopped for more than a minute
  • Reduce Weight: Remove unnecessary cargo
  • Proper Maintenance: Regular tune-ups and tire inflation

What Is the Fuel Cost & Emissions Calculator?

This tool helps estimate how much a trip will cost based on your vehicle type, fuel efficiency, distance, and current fuel prices. It also measures the environmental impact in terms of carbon emissions. It supports various vehicle types—including electric and hybrids—and provides personalized results based on real-world driving conditions.

Fuel Cost Formula

Total Fuel Cost = (Distance ÷ Adjusted Fuel Efficiency) × Fuel Price
Carbon Emissions = Fuel Consumed × Emission Factor (kg CO₂ per unit)

How to Use the Calculator

Follow these steps to estimate your fuel cost and environmental impact:

  • Select your vehicle type (Car, SUV, Truck, etc.).
  • Choose your fuel type (Gasoline, Diesel, Electric, etc.).
  • Enter your vehicle’s fuel efficiency using your preferred unit (MPG, L/100km, etc.).
  • Enter trip distance and select whether it’s in miles or kilometers.
  • Input current fuel or energy price based on your local currency and unit.
  • Adjust for real-world conditions like driving style, climate control use, and road type.
  • Click "Calculate" to view results including total fuel cost, consumption, emissions, and cost per mile/km.
  • Optional: View comparison charts, detailed calculations, and eco-driving tips to reduce impact.

Key Benefits

  • Helps you budget for trips more accurately.
  • Supports a wide range of fuel types and efficiency metrics.
  • Gives insight into how your driving behavior affects fuel use and emissions.
  • Visualizes emissions to promote more eco-friendly choices.
  • Offers actionable tips to improve fuel economy.

FAQs

What is fuel efficiency?

Fuel efficiency is a measure of how far your vehicle can travel using a certain amount of fuel. Higher efficiency means lower fuel consumption for the same distance.

Why does driving style affect the result?

Driving aggressively (rapid acceleration, hard braking) consumes more fuel. The calculator adjusts for driving habits to give a more realistic estimate.

What if I drive an electric vehicle?

Electric vehicle users can enter energy efficiency in kWh per mile or km. The calculator uses electricity prices and emissions data from average grid sources.

How are emissions calculated?

Each fuel type has a known CO₂ emission factor. The tool multiplies your fuel consumption by this factor to estimate carbon emissions.

Can I compare different vehicles?

Yes. Enable the “Show Vehicle Comparison” option to see how other vehicle types and fuel options perform over the same trip.
