a b s t r a c tMobility represents a relevant topic from the standpoint of environmental degradation, health-related consequences and social inclusion. Since private mobility is responsible for the greatest share of polluting emissions, it is necessary to gain deeper understanding of the mechanisms underpinning the choice of individuals to use either cars or alternative, environment-friendly transport modes. A meta-analysis on 58 primary studies is conducted to synthesize evidence on the determinants of travel mode choice, as regards both behavioral intentions and actual behaviors. Results suggest that, besides intentions, habits and past use represent the most relevant predictor, followed by constructs referring to the Theory of Planned Behavior framework. Environmental variables, on the other hand, play a relevant role in shaping behavioral intentions while their effect on actual behaviors is negligible, so that a deep intention behavior gap emerges. A moderator analysis is performed to explain the high heterogeneity in the results. Behaviors' operationalization and measurement emerges as the moderator affecting heterogeneity of outcomes the most; trip purpose, sample type and year of the study also show a moderate effect on heterogeneity, while location does not appear to be a relevant moderator.

Biofuels represent a promising alternative to substitute fossil fuels and, given the relevance of environmental impacts of the transport sector, policy initiatives worldwide aim at supporting the shift towards such cleaner energy source. Acknowledging the crucial role that biofuels will play in years to come in the energetic paradigm, the study aims at investigating key-determinants of drivers' willingness to pay for biofuels, focusing on a sample of 260 individuals from Northern Italy (n ¼ 260). In line with recent research on consumer behavior, socio-demographics are not good predictors of drivers' willingness to pay. Surprisingly, on the other hand, knowledge of the topic is negatively correlated to willingness to pay, so that the more people know about biofuels, the less they are willing to pay a premium price. Moreover, certification is not an effective tool to convince drivers of the eco-friendliness of biofuels, hence spurring willingness to pay. Possible explanations of the research findings as well as policy implications are discussed in detail, along with suggestions for future research on the topic.

Purpose The purpose of this paper is to present the results of a survey-based study performed on Italian SMEs in the “hotel, restaurant, café” (HORECA) sector, aimed at investigating the relationship between pro-environmental strategies and competitiveness and how such strategies can be exploited to outperform competitors. Design/methodology/approach The survey involved 317 Italian SMEs. Regression models have been developed to analyze the causal relationship between three dimensions of competitiveness (competitive advantage over competitors, customer satisfaction and employees’ motivation), and environmental practices that can be adopted by HORECA SMEs. Findings Top management commitment emerges as a key driver of competitiveness, confirming the strategic relevance of a sound approach to sustainability also in SMEs operating in the tourism sector. Moreover, actions aimed at investing in green food products (e.g. organic food) and awareness campaigns emerge as strong predictors of good business performance. Finally, at managerial level, entrepreneurs and owners evaluate the implementation of internal sustainability monitoring systems as a relevant support to increase their competitive performance. Research limitations/implications Since the results are limited to Italian HORECA businesses, a cross-country comparison could represent a potential improvement of the research. Moreover, since the sector is characterized by the predominance of small and micro firms, specific attention should be devoted to the role played by entrepreneurs’ personal values in shaping business strategies. Originality/value The paper contributes to the ongoing debate on the relationship between SMEs in the tourism sector and the environmental dimension analyzing the link between the adoption of “green” practices and the competitive performance. The results suggest that customer involvement represents an essential pre-requisite to turn sustainability into an opportunity of market distinctiveness and stress the strategic role of the implementation of performance monitoring systems.

Sustainable consumer behavior (SCB) gained significant attention given the relevance it bears for a broad set of actors. Since most of the relevant literature is rooted in western countries, researchers and policymakers implicitly assume that behaviors in developing countries tend to replicate those in developed countries. This review, based on seventy-one articles published since 2000, questions such assumption by analyzing the empirical research on SCBs in the Middle East and North Africa (MENA), a distinctive region that has been so far overlooked by mainstream research. Results reveal that most MENA-based papers are rooted in traditional frameworks of the rationalistic stream and that environmental values represent a key driver of SCB, while habits and socio-demographics are relegated to a negligible role. This study provides an added value by synthesizing the fragmented evidence on the topic and discussing aspects emerging as peculiar of the MENA and differentiating the latter from other societies.
