When Is It Permissible to Impose and Offset Risks? A Response to Barry and Cullity

Abstract

Christian Barry and Garrett Cullity argue that there is a morally important distinction between offsetting by “sequestering” and offsetting by “forestalling.” They further claim that offsetting by sequestering will often make risk-imposing actions permissible, while offsetting by forestalling typically will not. In this article, I highlight some reasons to be skeptical about their view and suggest an alternative account of the conditions in which offsetting can make a risk-imposing action permissible. In addition, I note a significant implication of my argument for the ethics of greenhouse gas offsetting.
