Until now, many kinds of persuasive applications have been developed, and most of which are used by individuals for personal benefits, example includes better healthcare, better lifestyle, etc. However, one application area that is yet to be explored effectively is persuading commons for preserving shared resources including environmental conservation. Unlike existing persuasive applications, these applications do not aim personal benefits and consequently requires radically different persuasion techniques. In this paper, we apply knowledge of cross-cultural understanding to this kind of persuasive applications. We introduce five design strategies for persuasive applications that could be used especially in collectivist cultures. By sharing our experiences of building persuasive application for reducing CO2 emissions, we expose how these five strategies could be applied in persuasive applications in collectivist cultures.
