Since the beginning of the $9 euros ticket for travel on the German rail system Deutsche Bahn on June 1, 2022 52 million tickets were sold. The ticket allows anyone to travel for 1 month in the months of June, July and August. It has saved 1.8 million tons of emissions because 20% of ticket users do not normally use public transport. A similar result in emissions savings can be achieved by lowering the speed limit on highways. A typical passenger emits about 4.6 tons of carbon a year in automobiles.
