Addressing global risks through ante-factum and post-factum mitigation

different meanings of the term mitigation across climate and pandemic debates

Abstract

The term mitigation plays a central role in both climate change and pandemic debates, yet it is used with markedly different – and often conflated – meanings across these domains. This article offers a systematic conceptual analysis of mitigation by distinguishing between ante-factum mitigation and post-factum mitigation. Ante-factum mitigation refers to measures aimed at reducing the likelihood that a harmful event will occur, whereas post-factum mitigation concerns efforts to prevent the worst consequences of an event that has already materialized. Drawing on the history of climate ethics, the article shows how early ambiguities surrounding mitigation, adaptation, and prevention re-emerged in pandemic ethics, particularly before and during the COVID-19 pandemic. The analysis demonstrates that much confusion in policy and ethical debates stems from shifting objects of mitigation rather than from substantive disagreement about goals. Clarifying these distinctions is essential for evaluating preparedness, response, and responsibility in the governance of global risks. The article concludes that conceptual precision regarding mitigation is indispensable for coherent ethical analysis and effective policymaking in both climate and pandemic contexts.
