The Metaverse is an important virtual venue in people's daily lives. This study examined whether pro-environmental behaviors in the Metaverse with a self-customized avatar lead to licensing effects, thereby reducing pro-environmental intention in reality. In addition, the study examined the mediating effect of self-presence on the relationship between avatar customization and pro-environmental behavior. A laboratory experiment was conducted using ZEPETO, a Metaverse platform. A total of 60 participants were randomly assigned to the self-customized avatar condition or the assigned avatar condition, and they engaged in pro-environmental behaviors on the Metaverse platform. Participants with self-customized avatars had less intention to engage in pro-environmental behavior in reality after engaging in pro-environmental behavior in the Metaverse than those with assigned avatars. Furthermore, self-presence partially mediated the relationship between avatar customization and pro-environmental intention.
