People forced to migrate due to environmental changes are an increasing concern, especially considering climate change threats and related adaptation strategies. Concurrently, migrations can have impacts on the natural environment of sending and receiving countries, at different scales. The article aims to discuss the role of social remittances in deepening our understanding about the relationship between environment and international migrations. In the first part we introduce the concepts of transnational migration and remittances in order to build a conceptual background. In the second section we focus on environmentally-related international migrations with the purpose of highlighting the role of social remittances in shaping the decision to migrate, in a context in which environmental factors should be considered as one of the multiple and intertwined causes. The third section analyses international migration impacts upon environment. Here, the "channel" of social remittances is discussed in relation to human influence on the envi-ronment of sending and receiving communities and countries.
