The willingness to pay for a carbon tax in Italy
Full text linkA carbon tax aimed specifically at the reduction of greenhouse gas (GHG) emissions produced by non-ETS sectors (and in particular, from transportation) has been proposed by policy makers on several occasions but has not yet been implemented in Italy. This paper aims to test the acceptability of such a measure and to quantify its amount by estimating Italian citizens’ willingness to pay (WTP) via two contingent valuation surveys involving a sample of 603 people. We find that the median WTP ranges from €101 to €154 if the payment vehicle is an annual fixed carbon tax, and from €0.17 to €0.30 per liter if the payment vehicle is a fuel carbon tax. Such values are found to be consistent with the social cost of the GHG emissions produced annually by an Italian citizen. Earmarking the carbon tax either to mitigate the environmental impacts of climate change or to finance renewable energy projects proves to substantially increase the respondents’ WTP. A number of other impacts on the WTP were also estimated, including: respondents’ attitudes and beliefs, their place of residence and mobility habits, and various socioeconomic and demographic characteristics. The policy implications of this evidence are discussed

No full textAssessing transport network resilience: empirical insights from real-world data studies.
Full text linkDetermining the factors that positively and negatively affect the resilience of transport networks provides valuable information that leads to a deeper understanding of the preparedness and response of networks to external disruptions. Over the past few decades, several review papers have explored various interpretations of transport network resilience and its calculation metrics. Nevertheless, only a limited number of these papers have paid attention on the utilisation of empirical data in resilience studies. This paper, through a systematic literature review, contributes to filling this gap. To this end, from a pool of 127 relevant articles, a subset of 53 articles using real-world data was selected. The paper analyses and classifies empirical findings in transport network resilience studies. In particular, it highlights and thoroughly discusses spatial patterns of resilience and relevant influencing factors that positively or negatively affect the resilience attributes of a transport network. Although it is possible to place the empirical results within the theoretical framework proposed by the literature, two main issues on target reference levels arise from the graphical representation of transport network resilience as suggested by the theory. Based on these findings, research gaps are identified and future directions for transport researchers are proposed
Environmental quality and accessibility trade-offs in household residential location choice

Full text linkThe 15-Minute City concept (FMC), proposed by Carlos Moreno, offers a chronourbanist approach to fostering sustainable, inclusive, and low-carbon urban living by promoting proximity-based access to daily services. This paper systematically reviews 113 peer-reviewed publications from 2021 to early 2025, sourced from Scopus and Web of Science using the PRISMA protocol, to evaluate how proximity is empirically
measured, its impacts on mobility, urban form, and spatial equity. Network-based accessibility models dominate proximity measurement, though slopesensitive modelling remains rare despite its importance for hilly cities. Evidence from Paris, Barcelona, and Lisbon shows that FMC strategies reduce car dependency, promote walking and cycling, and lower emissions. However, socio-spatial inequalities could persist, particularly for children, elderly, and low-income residents. Research remains heavily concentrated in Europe, North America, and East Asia, with minimal empirical evidence from the Global South. Key research gaps identified include the limited integration of urban freight and lastmile logistics into FMC frameworks, the lack of slope-adjusted accessibility models, insufficient investigation of traveller behaviour and perception of local services, limited attention to service quality and affordability, and the need for strategies to mitigate gentrification and displacement risks. Future research must address these areas to operationalise equitable, contextsensitive FMC strategies across diverse urban environments. This review offers an
evidence base for planners, policymakers, and researcher
Insights into peer-to-peer carsharing: Modelling and scenario analysis via a Bass diffusion agent-based model
Full text linkOur paper aims at estimating the uptake of peer-to-peer carsharing (P2PCS) in less-densely populated areas and how it could be influenced by innovation, social interaction and transport policies. We specified a Bass Diffusion agent-based model including two modules representing the supply and demand of P2PCS. Both modules are parametrized with data derived from a discrete choice survey of potential users (N = 449) representative of the population living in Friuli-Venezia Giulia, an Italian region bordering with Austria and Slovenia. We specified the rental rate as a dynamic variable that varies according to the excess of demand or supply. Innovation and imitation effects change the status of car owners and car drivers into potential P2PCS users. According to our simulations the P2PCS market would reach a steady state at a rental rate of 6.1 euro/h with 7% of car owners and car renters engaging in the system. We also found that if the preferences for the servitization paradigm were more diffused, P2PCS would be used by 11% of the population at a rental rate of 5.5 is an element of/h, and that adopting a package of highly effective policies supporting both the demand and the supply would increase the market share up to 42%
