In 1996, after protracted discussions and negotiations, agreement was finally reached on the Comprehensive Nuclear Test Ban Treaty (CTBT) banning nuclear test explosions in all environments. The treaty provides for an extensive verification regime, including an International Monitoring System (IMS), on-site inspections and confidence-building measures, which will be operated by the CTBT Organisation (CTBTO). While there are serious obstacles to be overcome before the treaty enters into force, considerable progress is being made in developing the verification system.

VERTIC’s project promotes the early implementation of the treaty and its verification system. Its activities include:

• monitoring, liasing with and contributing to the work of the Preparatory Commission (PrepCom) of the CTBT Organisation (CTBTO) and its Provisional Technical Secretariat (PTS) as it establishes the treaty’s verification system; and
• researching and publishing analyses of the progress made in and the challenges facing developing the CTBT’s verification system.

VERTIC seminar: 'Verifying the Comprehensive Nuclear Test Ban Treaty: Participation, Progress and Potential', 3 September 2003, Vienna
The Third Conference on Facilitating the Entry into Force of the CTBT was held in Vienna, Austria, from 3-5 September 2003.

VERTIC contributed to the conference by holding a lunchtime seminar on the first day, organised in co-operation with the Preparatory Commission for the CTBTO (PrepCom), to permit informal discussion of verification and related issues. This was the fourth such seminar VERTIC and the CTBTO have jointly organised. Some 50 delegates and representatives of non-governmental organisations (NGOs) attended it.

In his introductory statement (former) VERTIC Executive Director Trevor Findlay expressed the Centre's support for the early establishment of the complete verification system and noted the considerable progress made by the PrepCom and the PTS in setting up an International Monitoring System (IMS) and an International Data Centre (IDC), which collects, collates, distributes and processes the information. The first speaker at the seminar, Raymond J. Willemann, Director of the International Seismological Centre (ISC), discussed the role of non-IMS seismic stations in monitoring. He was followed by Robert Gough, Chief of the Methodology Section, On-site Inspections, in the PTS, who reported on the 2002 on-site inspection field experiment conducted in Kazakhstan. Finally, Rebecca Johnson, Executive Director of the Acronym Institute for Disarmament Diplomacy. A lively question and answer period followed.

VERTIC also helped draft the NGO Statement on the Comprehensive Nuclear-Test-Ban Treaty (CTBT) for the Third Article XIV Conference on Accelerating Entry-Into-Force. The statement was signed by nearly 100 other organisations and delivered by Dr Klaus Renholder of International Physicians for the Prevention of Nuclear War, Vienna on 5 September 2003. It called on all states to join the treaty and reaffirmed that a strengthened network of NGOs, governments, international organisations and media organisations would continue to promote early entry into force and exert pressure on the 12 Annex 2 states which have yet to sign or ratify the treaty.
