Abstract Environmental losses are increasingly evoking ‘‘ecological grief’’ among environmental and conservation professionals. Ecological grief is a natural but difficult psychological experience, and a risk to well‐being. Despite this, there are currently few resources available to support environmental professionals and their organizations to reduce the risks to well‐being and cope effectively with ecological grief. As a result, environmental professionals who experience this risk in the workplace are unlikely to be equipped with the knowledge, skills, or context to support themselves, colleagues, or peers, in experiences of ecological grief. In this paper, we provide information, guidance, and examples of workplace support for ecological grief. Drawing on insights from the field of grief and bereavement, we identify peer support and organizational responses as key supportive factors for those experiencing ecological grief. We also present a new concept, ‘‘ecological grief literacy,’’ to guide effective peer and organizational support. While peers have the potential to provide interpersonal support and connection for ecological grieving, it is essential that the organizations that employ environmental professionals enact policies and practices that provide structures, resources, and contexts to enable environmental professionals to effectively support ourselves and each other.
