"Ultimately, the work of The Carter Center is about helping people achieve better opportunities and watching hope take root where it languished before."—Jimmy Carter
The Carter Center, in partnership with Emory University, is guided by a fundamental commitment to human rights and the alleviation of human suffering; it seeks to prevent and resolve conflicts, enhance freedom and democracy, and improve health.
While the program agenda may change, The Carter Center is guided by five principles:
1. The Center emphasizes action and results. Based on careful research and analysis, it is prepared to take timely action on important and pressing issues.
2. The Center does not duplicate the effective efforts of others.
3. The Center addresses difficult problems and recognizes the possibility of failure as an acceptable risk.
4. The Center is nonpartisan and acts as a neutral in dispute resolution activities.
5. The Center believes that people can improve their lives when provided with the necessary skills, knowledge, and access to resources.
The Carter Center collaborates with other organizations, public or private, in carrying out its mission.
