Determine Fuel Consumption

First, calculate or obtain the total fuel consumption for your vehicle over a certain period. This can be measured in liters (for petrol or diesel) or in kilograms (for compressed natural gas, CNG).

2. Find the Emission Factor

Emission factors represent the amount of CO2 emitted per unit of fuel consumed. These factors can vary by fuel type. Here are some commonly used emission factors:

• Gasoline (Petrol): 2.31 kg CO2 per liter
• Diesel: 2.68 kg CO2 per liter
• Compressed Natural Gas (CNG): 2.75 kg CO2 per kilogram

3. Calculate the CO2 Emissions

The formula to calculate CO2 emissions is:

CO2 Emissions (kg)=Fuel Consumption × Emission Factor

Example Calculation

Suppose you have a car that consumes 100 liters of gasoline in a month.

Using the formula:

CO2 Emissions=100 liters×2.31 kg CO2/liter=231 kg CO2

So, your car emits 231 kg of CO2 in a month.

Additional Considerations

• Fuel Efficiency: More fuel-efficient vehicles will consume less fuel for the same distance traveled, resulting in lower CO2 emissions.
• Driving Behavior: Aggressive driving (speeding, rapid acceleration, and braking) can increase fuel consumption and CO2 emissions.
• Vehicle Maintenance: Proper maintenance ensures that your vehicle runs efficiently, consuming less fuel and emitting less CO2.

According to:

• 2006 IPCC Guidelines for National Greenhouse Gas Inventories" is a key reference for emission factors and calculation methods. IPCC (2006): "2006 IPCC Guidelines for National Greenhouse Gas Inventories," particularly Volume 2: Energy.
• The EPA’s "Emission Factors for Greenhouse Gas Inventories" document includes specific emission factors for different types of fuels. EPA (2022): "Emission Factors for Greenhouse Gas Inventories."
• The Greenhouse Gas Protocol, a collaboration between the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), provides standardized frameworks for measuring and managing GHG emissions. Greenhouse Gas Protocol (2015): "GHG Protocol Corporate Standard."

thank you for your answer, can you look at the https://efdb.apps.eea.europa.eu/?source=%7B%22query%22%3A%7B%22bool%22%3A%7B%22must%22%3A%5B%7B%22term%22%3A%7B%22code%22%3A%221.A.3.b.i%20Road%20transport%2C%20passenger%20cars%22%7D%7D%2C%7B%22term%22%3A%7B%22Fuel%22%3A%22Petrol%22%7D%7D%2C%7B%22term%22%3A%7B%22Pollutant%22%3A%22CO2%22%7D%7D%2C%7B%22term%22%3A%7B%22Type%22%3A%22Tier%202%20Emission%20Factor%22%7D%7D%5D%7D%7D%2C%22display_type%22%3A%22tabular%22%7D? the emission factors are based on gram/km and i have only km per vehicle in my dataset, not the fuel consumption per vehicle per household,

my question is why the emission factor in other references like https://www.eea.europa.eu/en/analysis/indicators/co2-performance-of-new-passenger are much higher than the emission factors in the reference that i used?
