[Extract] “Starbucks has a duty to ensure its coffee growers receive a decent wage.” “Medecins Sans Frontieres has a duty to operate in Syria.” “The United States has a duty to take the lead on climate change mitigation.” These are assertions about the duties of group agents. This article aims to answer two questions about such duties. First, are group agents’ duties identical to a collection of individual duties? Second, if a group agent fails to do its duty, does this imply that at least one member has failed to do their duty?
