Geneva will begin to offer temporary reductions on tickets to encourage  use of the city’s public transport network and reduce air pollution.

This was spurred after higher than normal levels of ozone were detected last month in the city’s suburbs and in the city centre, as well as across the wider Romande region.

‘Without wanting to trigger panic, this pollutant represents a real risk to children, the elderly and those suffering from respiratory problems,’ said Luc Barthassat, a cantonal official in Geneva.
