On December 16, 2012, Mraz headlined the Milestone Concert in Myanmar to raise awareness about human trafficking, making him the first foreign artist to play an open-air concert in Myanmar. The concert was organized by MTV EXIT and held in the People's Square in Yangon, with over 70,000 people in attendance, as part of an initiative to raise awareness about human trafficking in Myanmar. Also in 2012, Mraz spent a week in Antarctica with a group of environmentalists, scientists and researchers on a mission led by Al Gore, to learn about the effects of climate change.
