At the bottom of the list of the proportion of green cars is Ydre kommun with 0 percent.
In the top Linköping with 61 percent, but also in that municipality, the proportion has fallen from 68 percent in 2018.
Only those vehicles that run on electricity, bio or hydrogen gas are counted as green cars.
Fuel that is not always easy to refuel in smaller municipalities.
- We have looked at what the municipalities think in the vehicles and then the proportion of fossil-free cars increases - on average across all the county's municipalities from 35 percent in 2018 to 42 percent in 2019, says Ylva Ek, project manager for the energy office at Region Östergötland.
She believes that HVO is a good fuel during a transition period and that the EU is pushing hard towards electrification of vehicles.
- It has been easy for the transport sector to switch to HVO, but there is not enough HVO if the rest of Europe wakes up and also wants it.
