During street blockades and other protests by the climate group Last Generation, Berlin police officers alone have now worked 233,000 hours.
Interior Senator Iris Spranger (SPD) called the number on Monday in the Interior Committee of the Berlin House of Representatives.
756 suspects were found, 2700 criminal charges were filed and 761 processes were identified.
The last generation group started street blockades almost a year ago, with activists sticking themselves to the road.
There was also a protest on Monday: around 8 a.m., according to the police, eight people blocked the Beusselstraße exit on the A100 towards Wedding.
Four would have stuck.
Spranger said in the committee that a fee of 241 euros would be charged per mission.
In the meantime, a fine of 2,000 euros would be imposed on suspects who had stuck themselves in Berlin more than eight times.
The interior senator rated the protest actions as "politically motivated crimes", but also said: "Nevertheless, the border to extremism has not yet been crossed." .
"We cannot and will not tolerate that."
When asked by a member of parliament for information on the payment of the activists by a Berlin association, the senator said that the "climate stickers" themselves had made public "that they were paid, that they received donations".
The authorities would have a keen eye on where these funds come from.
"I'm not aware that the Berlin Senate supports an association that pays the activists."
