# CO2 Calculator - Emissions from Cars

Sponsored Links

### Online CO2calculator for travel by car

By filling in the required information, the calculator below can be used to estimate the CO2emissions from your travels by car.
Additionally, it compares with emissions from alternative ways of travel.

How far do you drive?

( For long distances, see distance table . Choose the nearest destinations for your trip)

What is the average fuel consumption of your car (not necessary for electrical cars)?

How many persons in your car?

Choose the actual kind of fuel in your car (definitions of the different electricities are given below):

Not sure how far you are going?   See Driving distance between European cities and Flight distances between cities in and between different continents.
See also CO2calculator - emissions from airplanes and CO2calculator- emissions from trains for more details for aircraft and train emissions.
Unit converter for conversion to and from non-SI units.

A few words about the assumptions for the calculator:

• In comparison with alternative ways of travel, the efficiency regard to distance is set to be:

Car:    1 (reference)
Plane: 0.82 km/km with car
Bus:   1.03 km/km with car
Train:  1.09 km/km with car
(The difference is due to varying driving lines for the different ways of transportation)

• The CO2emissions are strongly dependent on the energy source of the electrical cars. We have used three different classes:

Low CO2el: Mainly non-emission electric power (hydroelectric, sun, wind etc)
Medium CO2el: An even blend of non-emission electric power and power from power plants fired with hydrocarbons (gass, oil or coal)
High CO2el: Mainly power from hydrocarbon fired power plants

• CO2 emissions from alternative travel are calculated assuming:
1. Average filled up train, planes and buses.
• If running on electrical power, trains

have the same electricity source as the cars.

• Cars on liquid fuel are compared with electrical trains and cars using Medium CO2el.
