The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) relies on innovation to enhance the capabilities of the Treaty’s verification regime as well as to help move the Treaty closer to universalization and entry into force. As the sixth conference in the CTBT: Science and Technology series, SnT2021 is expected to bring together (physically as well as virtually) over 1000 scientists, technologists, academics, students and representatives of the CTBTO’s policy making organs.

In addition, representatives from the fields of research and development, science diplomacy, science advisory, media and advocacy will be present. The 25th anniversary of the opening for signature of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) presents an opportunity to review the scientific and technological advancements made and to project what developments can be expected in the next 25 years.

It is currently planned for SnT2021 to be hosted at the Hofburg Palace in Vienna, Austria, featuring a virtual component for active online participation. The structure of the conference will remain flexible to adapt for future changes of COVID-19 restrictions.
