In this article, I study non-material harm in cases of environmental liability. Environmental tragedy does not only come at great economic cost but often also brings about non-material loss – that is, loss that has no market value. In order to better recognize, assess, and measure this type of harm, more insight is needed into its psychological conception and parameters. Departing from the available legal frameworks on non-material harm in Belgium as well as in the Netherlands, I study how environmental psychology can help in recognizing, assessing, and measuring environmental non-material harm. More specifically, I focus on solastalgia, a notion that describes the psychological impact of negatively perceived changes to a familiar environment. Solastalgia describes a crisis of identity as a result of a disturbance in the way in which humans inhabit their environment. It describes a form of ecological grief over the loss of a familiar place – that is, the aggregate meanings, values, familiarity, and predictability attached to a specific environment. Using the available theoretical framework around solastalgia and the available empirical insights in the solastalgia literature, I show that solastalgia qualifies as a valid type of harm and bears significant advantages when implemented in environmental tort law frameworks.
