n Resolution 2532 (2020), the UN Security Council characterised the COVID-19 pandemic as an endangerment to international peace and security and, for the first time, demanded a general ceasefire and humanitarian pause in armed conflicts across the globe. This article analyses the resolution and its broader implications. In particular, it examines the significance of the Council’s characterisation of the COVID-19 pandemic, the binding powers of the Security Council for addressing threats to international peace and security which are not ‘threats to the peace’, and the implications for the Council’s mandate and the collective security framework. This article argues that the concept of ‘international peace and security’ under Article 24(1) of the United Nations (UN) Charter – rather than Article 39 ‘threats to the peace’ – is fundamental to the delimitation of the Security Council’s mandate and powers for addressing non-traditional threats to international peace and security such as pandemics and the climate crisis.
