The Association of German Transport Companies (VDV) draws a positive balance with the 9-euro ticket: According to this, 52 million tickets were sold, saving around 1,8 million tons of CO2 in this way.

The three-month special ticket campaign had a clear effect on the use of local public transport. Around 52 million tickets were sold nationwide over the entire period, the association announced at a joint video press conference with the conference of transport ministers of the federal states. "In addition, there are more than ten million subscribers who have automatically received the discounted ticket monthly over the campaign period," it said.

According to the VDV, there were an estimated one billion trips per month between June and August as a result of the special measure. Ten percent of the trips with the nine-euro ticket were used for a route that would otherwise have been driven by car. Overall, the proportion of trips shifted from other means of transport is 17 percent. The VDV estimates the amount of greenhouse gas saved at 1,8 million tons of CO2. That is roughly the same effect as if there had been a speed limit on German autobahns for a year, as the Tagesschau reports.
