To date, tourism is the fastest growing industry globally, but one of the least developed in terms of environmentally sustainable practices. However, only a small portion of documents elaborate on how the introduction of new technologies can impact a more sustainable development route for tourism. This study’s objective is to provide an overview on literature state-of-the-art related to sustainable tourism and technological innovations, offering insights for further advancing this domain. We employ a bibliometric analysis and a comprehensive review of 139 articles, collected from Web of Science and Scopus databases, for the purpose of: (i) exploring and discussing the most relevant contributions in the publication network: (ii) highlighting key issues and emerging topics; (iii) uncovering open questions for the future. Our findings reveal contradictory views on the risks and benefits of technology adoption. Artificial intelligence, internet of things, circular economy, big data, augmented and virtual reality emerge as major trends. Five work streams are identified and described, leading to a broader perspective on how technology can shape the future of sustainable tourism. Relevant theoretical and managerial implications are derived. Finally, a research agenda is proposed as guidance for future studies addressing the outcomes of digital disruption on sustainable tourism.

PurposeConsidering the relevance of understanding what influences environmentally sustainable consumer choices, the present study aims to examine and synthesize the key determinants factors from literature and outline a new conceptual framework for explaining green purchasing behaviors (GPBs).Design/methodology/approachA bibliometric analysis was conducted on 161 articles extracted from Web of Science and Scopus databases, which were systematically evaluated and reviewed, and represent the current GPB knowledge base. Content analysis, science mapping and bibliometric analysis techniques were applied to uncover the major theories and constructs from the state-of-the-art.FindingsThe evolving debate between altruistic and self-interest consumer motivations reveals challenges for rational-based theories, as most empirical applications are not focused on buying behaviors, but instead either on pro-environmental (non-buying) activities or on buying intentions. From the subset of leading contributions and emerging topics, nine thematic clusters are unveiled in this investigation, which were combined to create the new PSICHE framework with the purpose of predicting GPB: (P)roduct-related factors, (S)ocial influences, (I)ndividual factors, (C)oncerns about the environment, (H)abits and (E)motions.Practical implicationsBy uncovering the multiple intervening factors in GPB decision processes, this study will assist practitioners and academics to move forward on how to foster more sustainable consumer behaviors.Originality/valueThe present study provides readers a summary of an unprecedentedly broad collection of papers, from which the key themes are categorized, the domain's intellectual structure is captured and an actionable framework for enhancing the understanding GPB is proposed. Four new thrust areas and a set of future research questions are included.

PurposeThe current paper aims to explore how brand coolness can mediate the relationship between tactical green marketing orientation (GMO) and willingness to pay (WTP), by exploring the differences between two global brands with opposite green marketing perceptions.Design/methodology/approachBased on the stimuli-organism-response (S-O-R) framework, the relation between tactical GMO, brand coolness and consumer's WTP is examined through a survey with 272 participants, who gave their perceptions about two different brands regarding their green orientations: British Petroleum (BP) and L'Oréal. The variable set was adapted and validated through focus group sessions.FindingsBrand coolness is found to mediate the impact GMO on WTP and, for both brands, green marketing does affect the extent to which brands are perceived as cool by consumers. More importantly, evidence shows that only in the case of the “green brand” (e.g. L'Oréal), the impact on WTP is significant, which offers new implications regarding the outcomes of companies' pro-environmental policies.Originality/valueThis study is the first to investigate the outcomes of GMO over consumer's intentions (WTP) and the role of brand perceptions (coolness). The effects are compared between two global brands, with significantly different perceptions on their environmental sustainability.
