Profiles were paid to sell environmental zones

In the collaboration, the city hired former biathlete Björn Ferry and influencer Sara Ohlson to talk about Stockholm's environmental zone. The campaign was paid for with tax money. The opposition is critical, calling it "agenda-driven advertising."

Niklas Westergren, communications officer at the Swedish Transport Agency, defends the collaborations but says at the same time that they are not completely satisfied with the posts.

The ban on diesel and gasoline cars in a smaller zone in Stockholm city was supposed to be introduced at the turn of the year, but has been stopped in several instances.
