Transport Transition

Within the renewable transport transition, a number of alternative technologies have emerged creating competing visions of how to reduce fossil fuel dependence. This paper examines the dynamics of competing fuels in two Swedish municipalities where electric buses have emerged, threatening incumbent biogas-based bus systems. While in Linköping, actors are resistant to the promise of electrification, in Malmö the shift to electrify urban buses has already begun. Here, the theoretical perspectives of obduracy and sociotechnical imaginaries are used to analyze obduracy and change in Linköping and Malmö, showing how the local contexts of these two municipalities influence obduracy or willingness to change. In Linköping, perceived connections between the biogas-based bus system and local infrastructures of renewable waste management and organic food production cause actors to place biogas buses at the center of a sustainable future region, while in Malmö linkages to the gas network (which also distributes natural gas) cause actors to question the sustainability of the fuel in use and opens up the city to welcome new electric vehicle tests. These examples show how fuel alternatives interact with each other in the wider renewable energy transition.

Smart Mobility and the introduction of innovation in the complex and dynamic actor ecosystem of urban transport is faced with the need to manage change in order to secure sustainability and protect against negative externalities. The present contribution provides decision-makers with a tool to assess innovation strategies and monitor change over time. The proposed EcoSystem Innovation Framework (ESIF) is applied to a flagship innovation: Mobility as a Service (MaaS). The application concerns the City of Budapest, a location with highly-utilized resources and low car ownership, in contrast to other locations where MaaS is implemented. The ESIF is constructed through qualitative research (stakeholder workshops, interviews, document collection and analysis) for three (3) points in time: Summer 2018; Summer 2019 and end of 2020 (first year of the COVID-19 pandemic). The ESIF analysis was able to guide decision-makers and highlight potential future trends demonstrating the potential of the ESIF framework. For the City of Budapest, the ESIF highlighted the delicate balance in the promotion of MaaS, as the dichotomy between public and private on-demand mobility may trigger a negative modal shift. The COVID-19 pandemic has enhanced this potential. Despite public sector efforts, market opportunity has surfaced leading to contrasting interests in the ecosystem.

Economic Size

With the continuous expansion of urban scale, blindly increasing or controlling transportation infrastructure possibly creates a short board in an urban system. In this study, a macro traffic integrated system was constructed according to a city's economic size distribution and transportation infrastructure. The planning strategy of traffic, industry, space interaction and coordinated development was put forward. Through theoretical model, the evolution mechanism between transportation infrastructure and economic scale distribution was revealed. Starting from the center of the city and inter city level, China's new urbanization strategy was implemented, and a comprehensive transportation system model was built. The traffic planning in Singapore was taken as an example, and the solution to traffic problems such as congestion, traffic jam, and distance was obtained. Practice has proved that the rational and effective urban transportation infrastructure construction can effectively promote the coordinated development of economy and resources, and comprehensively enhance the level of integrated transport services.

The spatial visualization is a very useful tool to help decision-makers in the urban planning process to create future energy transition strategies, implementing energy efficiency and renewable energy technologies in the context of sustainable cities. Statistical methods are often used to understand the driving parameters of energy consumption but rarely used to evaluate future urban renovation scenarios. Simulating whole cities using energy demand softwares can be very extensive in terms of computer resources and data collection. A new methodology, using city archetypes is proposed, here, to simulate the energy consumption of urban areas including urban energy planning scenarios. The objective of this paper is to present an innovative solution for the computation and visualization of energy saving at the city scale.The energy demand of cities, as well as the micro-climatic conditions, are calculated by using a simplified 3D model designed as function of the city urban geometrical and physical characteristics. Data are extracted from a GIS database that was used in a previous study. In this paper, we showed how the number of buildings to be simulated can be drastically reduced without affecting the accuracy of the results. This model is then used to evaluate the influence of two set of renovation solutions. The energy consumption are then integrated back in the GIS to identify the areas in the city where refurbishment works are needed more rapidly. The city of Settimo Torinese (Italy) is used as a demonstrator for the proposed methodology, which can be applied to all cities worldwide with limited amount of information.

This study assesses changes in mobility behaviour in the City of Barcelona due the COVID‐19pandemic and its impact on air pollution and GHG emissions. Urban transport is an important sourceof global greenhouse gas (GHG) emissions. Improving urban mobility patterns is therefore crucial formitigating climate change. This study combines quantitative survey data and official governmentdata with in‐depth interviews with public administration officials of the City. Data illustrates thatBarcelona has experienced an unprecedented reduction in mobility during the lockdown (a 90%drop) and mobility remained at comparatively low levels throughout the year 2020. Most remarkableis the decrease in the use of public transport in 2020 compared to pre‐pandemic levels, whereas roadtraffic has decreased to a lesser extent and cycling surged at times to levels up to 60% higher thanpre‐pandemic levels. These changes in mobility have led to a radical and historic reduction in airpollution, with NO2 and PM10 concentration complying with WHO guidelines in 2020. Reductions inGHG emissions for Barcelona’s transport sector are estimated at almost 250.000 t CO2eq in 2020 (7%of the City’s overall annual emissions). The study derives policy implications aimed at achieving along‐term shift towards climate‐friendlier, low‐emission transport in Barcelona, namely how torecover lost demand in public transport and seize the opportunity that the crisis brings for reform byfurther reducing road traffic and establishing a 'cycling culture' in Barcelona, as already achieved inother European cities.

Considering the quest to meet both sustainable development and energy security goals, we explore the ramifications of explosive growth in the global demand for lithium to meet the needs for batteries in plug-in electric vehicles and grid-scale energy storage. We find that heavy dependence on lithium will create energy security risks because China has a dominant position in the lithium supply chain and both Europe and North America seek to curtail reliance on China throughout their supply chains. We also find that efforts to expand lithium mining have been much less successful in Chile, the United States, and Europe than in Australia. Local communities resist licensing of new lithium mines due to a variety of environmental, social, and economic concerns. There are alternative technologies that may make lithium mining more sustainable such as direct lithium extraction, but the timing of commercialization of this process is uncertain. Progress is also being made in battery recycling and in alternative battery designs that do not use lithium. Such advances are unlikely to attenuate the global rate of growth in lithium demand prior to 2030. We conclude that tradeoffs between sustainability and energy security are real, especially in the next decade.

The article presents an analysis of the impact of urban transport on the environmental situation in the metropolis. A variant of the database modification based on the results of monitoring of the level of pollution of the atmosphere, soil mantle and water surface is proposed. Data integration will allow assessing the effectiveness of the measures applied in the city to reduce the negative impact of urban transport and make operational management decisions.
