Bloggers confessing that they waste food, non-governmental organizations naming corporations selling unsustainably harvested seafood, and veterans apologizing to Native Americans at the Standing Rock Sioux Reservation for environmental and social devastation caused by the US government all signal the existence of action-oriented guilt and identity-oriented shame about participation in environmental degradation. Environmental Guilt and Shame demonstrates that these moral emotions are common among environmentally friendly segments of the US but have received little attention from environmental ethicists.

Environmental Guilt and Shame makes three major claims: first, individuals and collectives can have identity, agency, and responsibility and thus guilt and shame. Second, some agents, including collectives, should feel guilt and/or shame for environmental degradation if they hold environmental values and think that their actions shape and reveal their identity. Third, a number of conditions are required to conceptually, existentially, and practically deal with guilt and shame's effects on agents. These conditions can be developed and maintained through rituals. Existing rituals need more development to fully deal with individual and collective guilt and shame as well as the anthropogenic environmental degradation that may spark them.
