Calculate carbon emissions for car and bike trips
How your car compares to biking in terms of carbon emissions? Here is any easy and useful tool, Car vs. Bike Calculator. Enter your trip details into the calculator to find the difference in emissions between driving a car and riding a bike.
Introduction
How to Use the Calculator
To use the Car vs. Bike Calculator is easy . Here’s how you can:
Input Fields
 Distance: Enter the distance of your trip into the calculator to find out the emissions. (e.g.,
50
)  Distance Unit: Select the unit of distance (either miles or kilometers). (e.g.,
mi
)  Fuel Efficiency: Enter the fuel efficiency of your car into the calculator to see its impact. (e.g.,
25
)  Fuel Efficiency Unit: Choose the unit for fuel efficiency (MPG or liters per 100 kilometers). (e.g.,
mpg
)  Fuel Type: Select the type of fuel your car uses. (e.g.,
gasoline
)  Electricity Consumption: Enter the electricity consumption of your bike (Wh/km). (e.g.,
0.15
)
Formula
The calculator uses the following formulas to estimate emissions:
For Car Emissions:
Variables
Variable  Description 

Distance  Trip distance 
Distance Unit  Unit of distance (mi/km) 
Fuel Efficiency  Car’s fuel efficiency 
Fuel Efficiency Unit  Unit of fuel efficiency (mpg/l100km) 
Fuel Type  Type of fuel used (gasoline/diesel/electric) 
Electricity Consumption  Electricity consumption for bike (Wh/km) 
Emissions per Unit of Fuel  CO2 emissions per gallon or liter of fuel 
Calculation Examples
Example 1
For example your input is:
 Distance:
50
 Distance Unit:
mi
 Fuel Efficiency:
25
 Fuel Efficiency Unit:
mpg
 Fuel Type:
gasoline
 Electricity Consumption:
0.15
Calculation Steps:
1. Convert Distance to Miles:

 Distance:
50 mi
 Distance:
2. Fuel Efficiency:

 Fuel Efficiency:
25 mpg
 Fuel Efficiency:
3. Emissions per Unit of Fuel:

 For gasoline:
8887 grams of CO2 per gallon
 For gasoline:
4. Calculate Car Emissions:
$$\text{CarEmissions}=\left(\frac{50}{25}\right)\times 8887=2\times 8887=17774\text{gramsofCO2}$$
5. Calculate Bike Emissions:
$$\text{BikeEmissions}=50\times 0.15\times 13.7=102.75\text{gramsofCO2}$$
6. Result:

 Car Emissions:
17774 grams of CO2
 Bike Emissions:
102.75 grams of CO2
 Car Emissions:
Example 2
Foe example your input is:
 Distance:
80
 Distance Unit:
km
 Fuel Efficiency:
12
 Fuel Efficiency Unit:
l100km
 Fuel Type:
diesel
 Electricity Consumption:
0.2
Calculation Steps:
1. Convert Distance to Miles:

 Distance:
80 km = 80 \times 0.621371 = 49.71 mi
 Distance:
2. Convert Fuel Efficiency to MPG:

 Fuel Efficiency:
12 l/100km
 Convert to MPG:
235.215 / 12 = 19.60 mpg
 Fuel Efficiency:
3. Emissions per Unit of Fuel:

 For diesel:
10180 grams of CO2 per gallon
 For diesel:
4. Calculate Car Emissions:
$$\text{CarEmissions}=\left(\frac{49.71}{19.60}\right)\times 10180=2.54\times 10180=25857.2\text{gramsofCO2}$$
5. Calculate Bike Emissions:
$$\text{BikeEmissions}=49.71\times 0.2\times 13.7=136.81\text{gramsofCO2}$$
6. Result:

 Car Emissions:
25857.2 grams of CO2
 Bike Emissions:
136.81 grams of CO2
 Car Emissions:
