Integrating Environmental Sustainability into Strategic Planning in Tourism and Hospitality Industry, Supporting SDG 13: Climate Action: Systematic Review

The integration of environmental sustainability (ES) into strategic planning (SP) has become more vital in the tourism and hospitality (T&H) sector, due to its significant reliance on natural resources and environmental quality. This study seeks to analyze how ES is systematically integrated into strategic planning processes, identify critical dimensions and challenges, and evaluate the degree of organizational awareness and strategic focus on sustainability. A systematic literature review was conducted using the Scopus and Web of Science databases, covering global studies published between 2024 and 2025, resulting in a final sample of 43 articles. A hybrid deductive–inductive methodology was employed to integrate the data. The findings indicate that ES integration is a complex and iterative process involving governance and leadership, strategic development, resource and environmental management, stakeholder involvement, performance assessment, and the application of analytical and technological instruments. The results also emphasize emergent aspects such as digital innovation and adaptive planning. Despite this advancement, implementation is inconsistent due to capacity limitations, fragmented governance, data deficiencies, and environmental–economic trade-offs. The study illustrates a distinct convergence between ES and SP, signifying a transition towards integrated, evidence-based, and adaptable strategic systems. The study enhances the literature by delivering a thorough synthesis of integration mechanisms and presents practical insights for promoting sustainable strategic planning in the T&H sector.
