Reflecting the dynamic relationships between socio-technical behaviour and change, this book presents leading research on the transition process needed to realize a sustainable transport system. Focusing on making transition happen, this volume looks at various aspects and factors that are involved in materializing this process with implications for transport policy making. Bringing together scholars interested in sustainable mobility from various disciplines and countries to discuss the relationships between policy instruments, individual behaviour, institutional practices and the transition.

Decision-making on transport infrastucture projects in the Netherlands has been facing a remarkable wind of change in recent years. After a period of about a decade in the 1990s in which both academics and practitiones in policy analysis, public policy and planning have claimed that the traditional policy analysis methods were obsolete (be they CBA or MCA) because of their assumed one sidedness and lack of adaptability to the requirements of multi-actor settings, they experience a sudden resurgence since the year 2000 in the form of OEEI (Overview of Economic Effects of Infrastructure), a refined application of the wellknown CBA method. Astonishingly and despite all political and administrative theory on the types of information policy actors can process, the need for transparancy and active actor involvement in the evaluation and decision process, all at odds with traditional policy analysis, OEEI has become highly successful. This paper delves into the issue of why this new version of Cost Benefit Analysis has become so politically successful despite predictions made to the contrary. In addition, it will focus on the question if this resurgence may lead to 'econocracy' (concpetual hegemony by economists and thier ideologies and methods over other approaches) or not, and if so, how can this be prevented.

In globalization era, the role of ports is significant as the frontline of global trade. A port, as starting place of a port-city, delivers various impacts to city, not only positive impacts but also negative impacts during its operational activities and development. To deal with these port impacts, the port-city government should implement integrated policies to achieve sustainable development. This integration will cover land use, transportation and environment aspects. The existence of port-cities is important for Indonesia because as a big archipelagic state, Indonesia has over 294 ports which are located in port-cities. Semarang port-city, one of major port-cities in Java Island, is chosen as a case study because of its history since 1775 as a port-city and as a capital of the province in the colonial period in Java. The aim of this research is defining the role of integrated policy making in achieving sustainable development in Semarang port-city. The research design is a case study using qualitative data analysis and con/text analysis methods. Field work has been conducted in 2018 for 2.5 months by conducting observation and in-depth interviews. This paper discusses land use policy of Semarang and its response to impacts of port in Semarang only. The preliminary results indicate a complexity of authority among key stakeholders and a time constraint in process of making land use policy so that policy integration process will be more challenging. In addition there are involvements many policy makers who come from cross-sectoral and even stakeholders with different authority. Ultimately, the paper observes that to come to integrated policy making a framework for sustainable land use in port-cities relation needs to get a priority to realize the desired policy outcomes.

With scientific discoveries indicating a relationship between nitrogen oxides/particulate matter and cancers/heart disease, and the growing road transport sector in Western Europe, there is an increasing urgency to further reduce vehicle emissions. This comprises a large part of the total emissions in urban areas. In this article, we address the question of how various local policy instruments and technology can be used to support the use of clean road vehicles in urban areas. Despite some moderate success in specific areas, local policies and technology need to become even more effective. Using the STREAMS model, a comparative analysis is made of six urban cases in the Randstad and the Rhine-Ruhr metropolitan areas. The study provides new insights into the dynamics between the perceived problems, policy making (in terms of the adoption of policy instruments), politics (in terms of the fit/misfit between stakeholders' interests, which may result in a windo

© 2018 The Royal Society of Chemistry. Solar-powered electrochemical production of hydrogen through water electrolysis is an active and important research endeavor. However, technologies and roadmaps for implementation of this process do not exist. In this perspective paper, we describe potential pathways for solar-hydrogen technologies into the marketplace in the form of photoelectrochemical or photovoltaic-driven electrolysis devices and systems. We detail technical approaches for device and system architectures, economic drivers, societal perceptions, political impacts, technological challenges, and research opportunities. Implementation scenarios are broken down into short-term and long-term markets, and a specific technology roadmap is defined. In the short term, the only plausible economical option will be photovoltaic-driven electrolysis systems for niche applications. In the long term, electrochemical solar-hydrogen technologies could be deployed more broadly in energy markets but will require advances in the technology, significant cost reductions, and/or policy changes. Ultimately, a transition to a society that significantly relies on solar-hydrogen technologies will benefit from continued creativity and influence from the scientific community.
