Multilateral arms control, disarmament and non-proliferation

We aim to bolster the multilateral non-proliferation and disarmament regimes, particularly the nuclear Non-Proliferation Treaty. We provide ideas, analysis and research resources that support the efforts of serving diplomats in the NPT process. We also focus on specific regional challenges to the multilateral non-proliferation and disarmament system, including the future of nuclear diplomacy with Iran, and (in partnership with our sister Asia-Pacific Leadership Network) understanding Indo-Pacific perspectives on strategic risks. The ELN’s work has supported the P5 Dialogue, with a view to encouraging the NPT nuclear weapon states to engage jointly in strategic risk reduction. We also work to support the CTBT and encourage its entry into force and want to deepen the understanding of the concept of irreversibility in nuclear disarmament.
