Germany summer train fares reduction experiment finished on 31 August. Introduced on 1 June, the three month project to reduce car journeys, pollution and reduce curb imports of Russian oil has been judged a success, with about 1.8m tonnes of CO2 emissions being saved, although not all experts agree on this figure. The emissions saved were the equivalent to the powering of 350,000 homes.
About 52m tickets priced at 9 euros (£7.50) per month were sold, a fifth of them to people who did not usually use public transport. They gave unlimited travel on regional rail networks, trams and buses.
