The Project for the CTBT supports the work of NGOs and experts to build public and policymaker understanding of the CTBT.

In 1996, the United States was the first nation to sign the Comprehensive Nuclear Test Ban Treaty (CTBT), which “prohibits any nuclear weapon test explosion or any other nuclear explosion.” The CTBT helps curb the spread of nuclear weapons and establishes a global monitoring network to detect and deter cheating. The time for the CTBT is now.
