Thank you, Foreign Minister Johann Wadephul, for the warm welcome in Berlin and Germany’s steadfast support for the #CTBT. Thirty years on, our shared commitment remains clear: no return to nuclear weapons test explosions. Germany’s partnership is vital to sustaining the verification system that underpins that goal.

In Berlin, Executive Secretary @DrRobFloyd briefed the German Bundestag’s Subcommittee on Arms Control, Non-Proliferation and International Disarmament on the key role of the #CTBT and its verification system. The productive exchanges highlighted the importance of an effective losions and continued political support for the Treaty. (@hib_Nachrichten)

Marking 30 years of the Nuclear Test Ban Treaty #CTBT, #Germany remains a staunch supporter of its mission: a verifiable end to all nuclear testing. @CTBTO Ex. Sec. @DrRobFloyd & I agreed today: The CTBT global monitoring system is indispensable for international #security.

The Intl. Monitoring System (IMS) listens to the oceans and the earth for signs of nuclear test explosions, every hour of every day. That same data also reaches national tsunami warning centres in near real-time, under agreements with the States Signatories that operate them, they issue. On #WorldTsunamiAwarenessDay, that is worth recognising. More ➡️ ctbto.info/TsunamiWarnings

At the German Council on Foreign Relations (@dgapev) in Berlin, Executive Secretary @DrRobFloyd met with experts from think tanks and the policy community to discuss #CTBTO’s vital contribution to global peace and security and the role of civil society in advancing practical allenges.

One Treaty. One Goal. Zero Tests.
For 30 years, scientists, diplomats and dedicated people around the world have worked, step by step, towards a simple idea: no more nuclear test explosions. The Road to Zero tells the story behind the #CTBT and the people who made it happen.

🇧🇩 In Bangladesh, a #CTBTO mission successfully upgraded seismic equipment at auxiliary seismic station AS007 in Chattogram, confirming data transmission to the International Data Centre (IDC) in Vienna.

Working with the Bangladesh Atomic Energy Commission (BAEC), the National sh (NDC-BD) and local staff, the mission also strengthened national expertise through a two-day technical workshop.

With support from the European Union, this work helps strengthen global capabilities to detect nuclear test explosions under the #CTBT. 🌍

Watch highlights from High-Level Week as #CTBTO Executive Secretary @DrRobFloyd met with senior government representatives and joined high-level participants at the #IFE26 exercise field area in Namibia to observe surrogate inspectors carrying out on-site inspection activities ctional scenario.

We’re right in the midst of #IFE26 High-Level Week, and I’m delighted to be connecting with so many colleagues and partners. Their dedication and enthusiasm are a powerful reminder of what brings us together: a shared commitment to a world free of nuclear weapons testing.

High-level week has kicked off in Namibia 🇳🇦 as the Integrated Field Exercise moves into its next phase.

High-level representatives and the #CTBTO Executive Secretary @DrRobFloyd visited the exercise field area to observe surrogate inspectors carrying out the on-site inspection E26 fictional scenario.

A first-hand look at the techniques, people and capabilities behind the #IFE26.

A pleasure to meet Minister Selma Ashipala-Musavyi, @MIRT_NAMIBIA, and Minister Modestus Amutse, @MIMEnamibia. Thank you for an engaging exchange and for Namibia’s generous support in hosting #IFE26, our largest-ever on-site inspection exercise and the first in Africa. Together, world without nuclear tests and advancing peace and security for all.

As #DisarmamentWeek begins, we highlight the contribution international treaties make to non-proliferation and disarmament. The #CTBT bans nuclear test explosions everywhere, by everyone. In doing so, it holds back the development of nuclear weapons, and keeps the wider goal in reach.

#OTD in 1945, the UN Charter entered into force, setting out a commitment to international cooperation that has shaped the decades since. The CTBTO works in that spirit: a global ban on nuclear test explosions, verified by a system States built and sustain together. #UNDay

The National Data Centre (NDC) Infrasound Data Analysis Training in Vienna brought together 15 participants from 14 States Signatories last week. Through lectures and hands-on exercises, participants improved their practical skills in infrasound data processing, phase detection, -term detection analysis visualisation, enhancing national technical capabilities in support of the #CTBT verification system.

Catch up to the first two weeks of the Integrated Field Exercise 2026: from the launch phase week in Vienna, to the field operations week in Swakopmund and the Erongo Region, in Namibia.
The participants have entered a routine after a busy week of activities, and now they e field-gathering missions, collect data, and use search logic to further advance their work and narrow down the exercise inspection area. The IFE26 aims to validate and refine on-site inspection capabilities in preparation for the #CTBT’s entry into force.

A year ago, the world lost Jane Goodall. In The Road to Zero, she speaks about the CTBT as plainly as she spoke about everything that mattered to her: proud of how far it has come, unflinching about what’s left, countries still to sign and ratify. Her words are part of our short l film: ctbto.info/R20ShortFilm

The 70th session of #CTBTO’s Working Group A opened in Vienna, with Executive Secretary @DrRobFloyd highlighting key achievements: a growing Treaty family, a near-complete global monitoring system and the ongoing #IFE26 in Namibia. “We’ve invested so much to achieve all of this. protecting that investment in the years ahead.” He stressed the importance of sustainment, modernisation and long-term readiness, and thanked 🇵🇭 Amb. Evangelina Lourdes Bernas for her leadership as WGA Chair.

Timely meeting and an in-depth conversation on the work of the @CTBTO. EU and its Member States’ support is essential for strenghtening the verification regime and advancing the global regime against nuclear testing.

Thank you Ambassador Cullinane @IrlEmbVienna!

💫 Snapshots from a few days of youth engagement celebrating #CTBT30 and #CYL10!

#CYL met with @DrRobFloyd, explored the verification regime, engaged with students at the @CTBTO Exhibition & @UN partners, and championed youth voices in Vienna 🇦🇹

Thank you 🇪🇺 for your support!

Very interesting and timely discussions this morning between the EU Heads of Missions and @CTBTO Executive Secretary @DrRobFloyd , hosted by the Permanent Mission of Ireland during Ireland’s Presidency of the Council of the European Union 🇪🇺🇮🇪 @ireland2026eu #ireland2026eu
