In 2014, Brown helped launch A World at School's #UpForSchool petition – a global campaign started by A World at School's Global Youth Ambassadors – at a youth rally in New York City, alongside Graça Machel, Avaaz founder Ricken Patel, #BringBackOurGirls campaigner Hadiza Bela Usman, CNN anchor Isha Sesay, UN Special Envoy for Global Education Gordon Brown, and messages of support from UN Secretary-General Ban Ki-moon and actor Rainn Wilson. The petition aims to hold world leaders to account for the promise of universal primary education made in the Millennium Development Goals (MDG2).
