How we have calculated
With data from IVL, the Swedish Environmental Research Institute, we have calculated the vehicles' carbon dioxide emissions for their entire life cycle (manufacturing and operation).
The graph shows the carbon dioxide emissions if 50 people choose electric bus (181g CO₂/km), compared to if the corresponding number travel by electric car (50/1.4x58g CO₂/km when charging with Swedish electric mix) or fossil car (50/1.4x182g CO₂/km). In the calculation, we have assumed that 1.4 people travel in each car, which is the Swedish average based on statistics from 2021.
It requires more emissions to manufacture an electric bus than a car, but the environmental impact is compensated with less emissions when there are many of us who travel by electric bus.
