Overview

Engineering reference data for CO2 Emissions Transport Car Plane Train Bus in environment.

$E = E_F \cdot EF$

Emission factor × activity.

$CF = \sum (Activity_i \times EF_i)$

Sum of all emission sources.

Symbol	Description	Unit
$E$	Emissions	kg CO₂
$EF$	Emission factor	kg/unit

The calculator uses the following efficiency ratios to account for differences in travel distances between transportation modes:

These ratios reflect variations in driving lines for each mode.

The CO2 emissions from electrical vehicles depend on the electricity source. The calculator defines three classes:

Low CO2 el: Mainly non-emission electric power (e.g., hydroelectric, solar, wind)
Medium CO2 el: An even blend of non-emission electric power and power from hydrocarbon-fired power plants (gas, oil, or coal)
High CO2 el: Mainly power from hydrocarbon-fired power plants

CO2 emissions from alternative travel modes are calculated based on these assumptions:

Trains, planes, and buses are assumed to be on average filled up.
For electrical trains, the electricity source is the same as that used for cars.
Cars using liquid fuel are compared with electrical trains and cars using Medium CO2 el electricity.
