Ensuring that the growing mobility demand is met in a sustainable manner is important for our climate goals, and this would require changes to our current mobility behaviours. Behaviour and behaviour change theories have an important role in informing the mobility behaviour research and practices that seek to achieve these changes, and this paper d...

... this can be construed in the construct of habit, which is found in some theorisations and is increasingly popular in studies, the experience postdecision or post-behaviour would also change other important cognitive and emotional antecedents, such as norms and beliefs. This feedback loop (see Figure 2 for an illustration) is currently understudied but would be greatly beneficial when studying and predicting the effectiveness of interventions, policies, and programmes. New findings, including the proposal of new antecedents and relationships, will broaden our understanding and to encourage further use of theories by researchers and practitioners. ...

... All these emerging empirical studies, approaches, combination of models, integration of theories, and new theories have a common goal: to better understand the determinants of PEB and practices, including psychological, sociological, economic, cognitive, affective, rational, or irrational ones. Chng [44] proposes some ideas to respond to the number of theories today that make choosing one over another a challenge. One of them is to integrate and summarize multiple individual theories into a comprehensive and accessible framework for researchers. ...

Research on solutions for climate change in the urban transport sector has focused primarily on the technological and spatial planning perspectives; the social dimension of behavioral changes is relatively less explored, particularly in the southern European small city context. In this paper, we examine how social determinants and two other endogenous factors—motivation and knowledge—influence sustainable mobility choices in Portugal, through a case study of a city micro-mobility pilot, using the Elaboration Likelihood Model (ELM) and the Social Information Processing Theory (SIPT) as an analytical framework, and mix-method analysis from questionnaires, in-depth individual interviews, and other information collected throughout the pilot program. Motivation, as we found, was the strongest factor that contributed to comprehension, leading to a primarily positive attitude change towards pro-environmental behavior. Our research emphasizes the importance of mechanisms that stimulate citizens’ motivation and facilitate communication in sustainability pilot programs.

The direct coal liquefaction process usually produces a liquefaction residue of about 30% of its coal feed. The effective utilization of the coal liquefaction residue (CLR), which contains about 80% organic matter, is of great significancefor improving the oil yield of the direct liquefaction process and reducing the amount of pollution emitted from this oil-containing organic solid waste. In this study, the CLR fluidized bed pyrolysis process was studied through a fluidized bed reactor pyrolysis experiment and steady-state thermal analysis. The characteristics of CLR were first analyzed, and then the pyrolysis experiment was conducted in a fluidized bed reactor system. The experiment results show that the oil yield is 34.81% at 540°C for an ash-free feedstock using a fluidized bed pyrolysis reactor. Based on the pyrolysis experimental data and the Aspen Plus software platform, the fluidized bed pyrolysis reactor, fractionation column, coke burner, gasifier, and other equipment were modeled to compare four different process schemes. CLR pyrolysis is an endothermic reaction, and its heat is usually supplied by coke combustion, which produces significant CO2 emissions. Case studies of the pyrolysis process were performed in detail in order to reduce CO2 emissions. Thermal efficiency, carbon efficiency, solid waste discharge, and CO2 emissions of the different schemes were compared, and a flexible fluidized pyrolysis (FFP) process coupled with water electrolysis was proposed. The introduction of green hydrogen and green oxygen to the process can realize near-complete utilization of carbon and hydrogen elements in the CLR and produce high-quality liquid fuels and syngas (for further chemical synthesis), and this new process can achieve almost near-zero CO2 emission in the entire unit. This process principle can also be applied to the CO2 emission reduction of organic solid waste pyrolysis, catalytical fluid cracking, fluid coking, and so on.

... A limited set of predictors of acceptance was explored in this study even as more comprehensive and dedicated theories of AV acceptance have emerged (e.g., the multi-level model on automated vehicle acceptance by [22]). Hence, future studies could look into employing these more comprehensive theories in their investigations to better account for the multi-faceted nature of decision-making surrounding AV acceptance [45]. This study also acknowledges that the obtained data are hypothetical, due to the use of a stated preference survey, and cross-sectional in nature. ...
Shared autonomous vehicles (AVs) will soon be introduced in public transportation as cities and their transportation systems become ‘smarter’. This brings long-term environmental, economic and societal benefits to cities. However, shared AVs will not only need to overcome technological challenges but also prevail against social barriers for successful marketplace penetration. Hence, we proposed and investigated the acceptance of four shared AV service designs for public use in this study, namely, autonomous buses, shuttles, AV rideshares and autonomous or robo-taxis. An online survey conducted in Singapore with 734 adults found the greatest receptiveness toward the introduction of autonomous shuttles, in part due to perceptions that they will perform well and be easy to adopt. This aligns with ongoing shared AV trials where AV shuttles are mostly used. Larger autonomous buses had the second-highest acceptance. AV rideshares and taxis seem to largely appeal to the existing regular users of the conventional counterparts of these services. These results suggest that to encourage a mode switch from public transport to ridesharing and taxis, or vice versa, shared AVs need to appeal to users beyond being an automated version of existing modes. That is, shared AVs need to address an underserved or unmet transportation need or population.

Conventional fuels for vehicular applications generate hazardous pollutants which have an adverse effect on the environment. Therefore, there is a high demand to shift towards environment-friendly vehicles for the present mobility sector. This paper highlights sustainable mobility and specifically sustainable transportation as a solution to reduce GHG emissions. Thus, hydrogen fuel-based vehicular technologies have started blooming and have gained significance following the zero-emission policy, focusing on various types of sustainable motilities and their limitations. Serving an incredible deliverance of energy by hydrogen fuel combustion engines, hydrogen can revolution various transportation sectors. In this study, the aspects of hydrogen as a fuel for sustainable mobility sectors have been investigated. In order to reduce the GHG (Green House Gas) emission from fossil fuel vehicles, researchers have paid their focus for research and development on hydrogen fuel vehicles and proton exchange fuel cells. Also, its development and progress in all mobility sectors in various countries have been scrutinized to measure the feasibility of sustainable mobility as a future. This, paper is an inclusive review of hydrogen-based mobility in various sectors of transportation, in particular fuel cell cars, that provides information on various technologies adapted with time to add more towards perfection. When compared to electric vehicles with a 200-mile range, fuel cell cars have a lower driving cost in all of the 2035 and 2050 scenarios. To stimulate the use of hydrogen as a passenger automobile fuel, the cost of a hydrogen fuel cell vehicle (FCV) must be brought down to at least the same level as an electric vehicle. Compared to gasoline cars, fuel cell vehicles use 43% less energy and generate 40% less CO 2 .
... While social psychologists may favour methodological individualism and social practice theorists emphasise structural influences, a body of work argues that researching sustainable behaviour change can benefit from drawing upon a multitude of approaches (Burke et al., 2018;Chung, 2021;Lorenzoni et al., 2007;Whitmarsh et al., 2011;Wilson & Chatterton, 2011). A paper titled 'Multiple models to inform climate change policy: A pragmatic response to the 'beyond the ABC' debate' uses the analogy of blind men attempting to make sense of an elephant to emphasise the point (Wilson & Chatterton, 2011). ...

Given that a body of work argues for using a multitude of approaches to understand and explore sustainable behaviour change (Burke et al., 2018;Chung, 2021;Lorenzoni et al., 2007;Whitmarsh et al., 2011;Wilson & Chatterton, 2011), I also draw upon two key frameworks from social psychology as part of my study. The first is Erving Goffman's theory of frontstage (public) and backstage (private) behaviours (Goffman, 2012). ...
