Southwestern Pennsylvania in 2012 will once again play host to leaders from around the globe – although the ages of the participants will skew far younger than those who gathered for the G-20 Summit in 2009.

Pittsburgh will host the “One Young World” summit Oct. 18-22, 2012. The announcement came late Saturday in Zurich, Switzerland at this year’s conference. Johannesburg, South Africa will host in 2013.

Started in London last year, the gathering aims to develop young leaders to address issues of global business, health, the environment, interfaith dialogue and media. Counselors for the 2011 summit included anti-apartheid activist Archbishop Desmond Tutu, Bangladeshi micro-lending pioneer Mohammad Yunus, Irish rocker and anti-poverty activist Bob Geldof, and Wael Ghonim, the Google marketing director who spurred revolution in his native Egypt through his Facebook posts.
