Since 1971, the Arms Control Association has promoted practical solutions to address the dangers posed by the world's most dangerous weapons-nuclear, biological, and chemical, as well as certain types of conventional arms.

Every year since 2007, ACA's staff has nominated several individuals and institutions that best exemplify leadership and action in pursuing effective arms control solutions.

Each, in their own way, has provided leadership to help reduce weapons-related security threats.

Among the nominees are the governments of Australia, Belgium, the Czech Republic, Hungary, Italy, and Poland for pledging at the 2012 Nuclear Security Summit in Seoul that they would return their stocks of highly enriched uranium to the country of origin, with some of them specifying that they would complete their work by the end of 2013.
