Application of Proknow-C for the Systematic Analysis of Literature on the Influence of Carbon Footprint Reduction Measures on the Choice of Accommodation Reservation

The tourism sector is directly related to high energy consumption. In this context, measuring the ecological footprint generated by tourism is crucial to address environmental challenges. Hotels play a prominent role in this footprint due to their size and daily operations, which consume large amounts of energy and natural resources. The objective of this research is to analyze the state of the question of the influence of this carbon footprint reduction in tourist accommodation, especially hotels. The method used is based on the application of the Knowledge Development Process—Constructivist (ProKnow-C), providing a structured, rigorous procedure that minimizes the use of randomness and subjectivity in the bibliographic review process, as well as its subsequent analysis in the Bibliometrix program. As results, 7 relevant articles are obtained and aligned with the research topic, making it possible to identify the main approaches proposed by the authors of this bibliographic portfolio in relation to the problem raised. The present research can be used as a guide for the construction of knowledge in a systematic way and provides, both academics and professionals, a better overview to understand the contributions of the carbon footprint in the accommodation reservation, especially hotels. Through the bibliometric analysis, it was possible to identify relevant data from the 7 articles in the final portfolio, such as the main words and their correlation, the main authors, the production of said authors over time, etc., which can be presented as an opportunity for future researchers.
