Walk, ride a bike, or hop on a bus in Vienna, and you could be closer to a free concert or trip to a museum.

On Monday, the city launched a new app that tracks users' modes of transportation. It calculates the amount of carbon dioxide (CO2) savings in comparison to driving a car, and once users save 40 pounds of CO2, they receive one "culture token." Tokens are then exchanged for free tickets to participating cultural institutions.

"We want to reward CO2 reduction with a cultural experience," said Peter Hanke, a member of the Vienna City Council. Right now, the app is being tested by 1,000 people, but if the trial is successful, the app will open to the broader public in the fall, AFP reports. Austria's goal is to be climate neutral by 2040.

First lady Melania Trump is officially donning a face mask during the COVID-19 pandemic, although the jury's still out on whether her husband will follow suit.

In a social media post Thursday, the first lady shared a photo of herself wearing what appears to be a surgical mask, touting the Centers for Disease Control and Prevention's recommendation "to wear cloth face coverings."

"Remember, this does NOT replace the importance of social distancing," she wrote. "It is recommended to keep us all safe."

Melania's masking comes one week after President Trump announced he would not be wearing a mask, despite the CDC-issued guidelines urging people to do so. At the time, Trump implied that it would be odd to be "sitting in the Oval Office, behind that beautiful Resolute Desk" while wearing a mask, so it's unclear how he's taking this news.

The photo of the first lady appears to show her wearing a surgical mask rather than the CDC-recommended "cloth face covering," the former of which is recommended only for use by health care professionals and medical first responders amid critical supply shortages.
