This chapter is motivated by the growing recognition that cultural heritage plays a significant role across environmental, social, and economic dimensions of sustainability, while approaches to its valuation remain fragmented along disciplinary lines. The aim of the article is to examine how three key disciplinary domains conceptualize cultural heritage value and assess cultural heritage derived impacts. Specifically, the research asks how these disciplinary approaches overlap, where their conceptual and methodological gaps lie, and how their respective understandings of value shape what is made visible or invisible in heritage-related decision-making. While each of these perspectives illuminates particular dimensions of heritage meaning and impact, their separation into disciplinary silos limits the ability to grasp heritage as a systemic and relational phenomenon. To address this challenge, the article develops a three-level analytical framework that brings these disciplinary perspectives into a shared conceptual space. Rather than proposing a new paradigm of cultural heritage value, the framework functions as an organizing structure that positions existing approaches as complementary, allowing their insights to be compared, aligned, and interpreted together. By doing so, it enables the simultaneous consideration of the impacts of heritage on society and the environment, as well as the impacts of social, economic, and environmental processes on heritage itself. In this way, the framework supports symmetrical and integrated understanding of the cultural heritage valuation domains, consistent with the view of heritage as a dynamic system of interactions embedded within broader sustainability agendas.
