Cleaner air as drivers stay home for Obama's visit

US President Barack Obama's Stockholm visit has literally brought a breath of fresh air to the capital, TT news agency reports.

According to air samples taken around town, Stockholm's air quality has seen a drop in car emissions thanks to reduced traffic in the city center. Street closures caused traffic numbers to fall by nearly 40 percent on Wednesday as many drivers left their vehicles at home.

As a result, emissions fell sharply. For instance, nitrogen dioxide levels on Sveavägen declined by more than 30 percent.

"Traffic is the largest source of emissions we have in Stockholm," said Michael Norman with the environmental department at Stockholm City Council.
