["Corporate Social Responsibility and Environmental Management, EarlyView. ", "\nABSTRACT\nResearch on readiness and maturity for the smart circular economy (SCE) remains fragmented, especially in the hospitality sector. This study develops a multidimensional framework that integrates the principles of the circular economy, Industry 4.0, and sustainability performance in the context of tourist accommodations. To this end, a systematic literature review and the Delphi method were used to unveil and validate the key dimensions and sub‐dimensions that enable the assessment of SCE readiness and maturity in the sector. The panel of experts that completed all Delphi rounds consisted of 19 participants from the hospitality sector and related institutions, representing seven countries across three continents, with the aim of moving towards a broader and more robust consensus. As a result, the study presents a novel framework that includes 14 dimensions and 66 sub‐dimensions essential for assessing the level of implementation of the SCE at three levels: organizational, interorganizational, and ecosystem.\n"]
