Can a city toll help Bangkok clean up its air and roads?

Transport, which accounts for almost a third of global energy related emissions, is a key focus area of Thailand's climate goals. 

In Bangkok, heavy traffic means drivers often spend hours sitting in traffic, while many buses are decades old and run on diesel. 

To tackle air pollution and help reduce emissions, the city is introducing a new toll. They hope the congestion charge will help deter residents from commuting in private vehicles and opt instead for modernized public transport. To find out more, we visited the streets of Bangkok to accompany a commuter on her way to work.
