The article describes a research paper on sustainable interior design, emphasizing the growing need to apply ecological considerations in design processes. The study focuses on analyzing the potential of using natural materials in the interior design of single-family homes, as well as on educating interior design students in the field of ecological design. The methodology includes the aggregation of data related to green finishing materials, with a focus on their origin, manufacturing processes and carbon footprint. An integral part of the study is a survey of students to assess their knowledge and understanding of sustainable design. The research process is preceded by a series of lectures and the results, gathered from a group of students, are then incorporated into the author's interior designs. The resulting projects confirm a growing environmental awareness among the group studied and an understanding of the fundamental aspects of sustainable interior design. The conclusions underscore the urgent need to develop environmental education in the context of interior design. The use of eco-friendly materials contributes to both the aesthetic harmony of interiors and environmental protection. The article argues that sustainable interior design is not just a passing trend, but a key requirement of the modern age. Raising public awareness in this field, including through education, is the foundation for the effective development of this field. The responsibility of interior designers in terms of material selection and design practices is considered a priority.
