The Chemical Weapons Convention (CWC) has been successful in overseeing the destruction of declared chemical weapon stockpiles, but its role as a model for the permanent abolition of all chemical weapons requires careful consideration. Drawing on the speaking notes for the author’s presentation to the Conference that this volume records, this paper reflects on thoughts and dynamics that may aid efforts to maintain and develop the CWC as a sustainable model of chemical weapons abolition. It briefly unpacks the expectations and assumptions surrounding the CWC’s potential as a model for WMD abolition, suggesting that approaches to reviewing relevant science and technology, outreach and engagement, and efforts to leverage expertise and networks can be informed by the experiences of other international regimes in pursuit of maintaining a permanent abolition of chemical weapons beyond and including those classed as WMD. The paper suggests that learning from other regimes and adapting to new realities can strengthen the CWC’s role as a living, evolving model for abolition. However, realising this potential will require a shared vision and commitment from all stakeholders, including states parties and civil society, as well as a willingness to invest in the necessary capabilities and partnerships.
