**Abstract:** The aim of this study is to evaluate the existing available methods that can potentially be applied to anthropogenic spatial entities to access their environmental sustainability. The paper offers an overview of existing sustainability assessment methods, discusses their adequacy, and evaluates their efficiency to assess the environmental sustainability of anthropogenic spatial entities. From a list of sixty-one (61) sustainability assessment methods for spatial entities with anthropogenic activities that had been identified and examined, thirteen (13) methods were selected to be assessed based on specific exclusion criteria set. The thirteen methods were further classified into four categories, namely, (1) Indicators/Indices, (2) Resource Availability Assessment, (3) Material and Energy Flow Analysis, and (4) Life-Cycle Assessment, and then these methods were evaluated using specific evaluation criteria. The "Resource Availability Assessment" category, and particularly the "Ecological Footprint" method, was indicated as the most appropriate method to assess the environmental sustainability of anthropogenic spatial entities.
