City logistics is undergoing a transformative shift towards sustainability and efficiency. The environmental impacts of traditional delivery methods, coupled with urbanization, have driven the investigation of alternatives, including eco-friendly transportation modes. Among these, electric cargo bikes have emerged as a promising solution to reduce carbon emissions and congestion. This article delves into this case by evaluating a delivery service using electric cargo bikes using empirical data analysis, route optimization, and simulation. The findings support the strategic integration of electric cargo bikes with urban logistics hubs, enhancing the overall efficiency of last-mile deliveries. This research contributes to sustainable urban freight transport, providing information to city authorities, logistics operators, and policymakers. By establishing a robust framework for the deployment of electric cargo bikes in medium-sized cities, the study underscores the importance of innovative and sustainable solutions in transforming urban freight systems, aligning with global sustainability goals and improving urban livability.

The shift from road to rail in freight transportation is a crucial policy for reducing carbon emissions, but the effectiveness of the modal shift policy remains unclear. To evaluate the contribution of such modal shift to carbon neutrality in the transportation sector, this study employs a computable general equilibrium (CGE) model and introduces an innovative method to integrate time costs into the model. The results indicate that modal shift could cumulatively reduce carbon emissions by 175Mt to 198Mt between 2021 and 2060, with China’s gross domestic product (GDP) projected to decline by 0.08% to 0.10%. However, when accounting for the time cost, GDP losses could be more than three times higher than if time costs were excluded. Moreover, early rapid modal shift leads to greater carbon reductions and smaller economic losses compared with constant speed and late rapid modal shift.

E-scooter sharing (ESS) is an emerging shared micro-mobility that may enhance urban travel accessibility. This study investigates the potential of ESS used as the feeder to public transit to improve accessibility compared to sole public transit. Meanwhile, the relationships among accessibility gains, the built environment, and socioeconomic distributions are investigated based on multi-source big data. An empirical analysis in Gothenburg of Sweden demonstrates that ESS can substantially enhance accessibility within a 30-minute travel time, with 15% of areas showing statistically significant benefits. Moreover, the accessibility gains exhibit complex nonlinear relationships with the built environment and socioeconomic. High-income and native-born communities obtain an average of 80% accessibility gain, over 10% higher than other demographic groups. Some areas with significant concentrations of low-income and foreign-born populations rely on public transit but currently lack ESS to improve accessibility. Introducing ESS in these under-served areas could yield up to 143% accessibility gains.

Fluctuating operating costs (OC) create uncertainty around the benefits of electric vehicles (EVs). This study is the first to explore how uncertain OC impacts EV preferences using an extended decision field theory (DFT). We examine Singaporean ride-hailing drivers’ EV rental choices under uncertain OC, finding that extended DFT outperforms prospect theory. Incorporating eye-tracking data further improves DFT’s explanatory power, leading to two insights. First, younger, frequent, long-distance drivers are more inclined to adopt EVs and are more affected by uncertainty in OC. For example, for drivers with a daily OC of $25, a 20% chance of a $12.5 increase in OC reduces EV preference by 1.5%. Second, providing drivers with clear information on predictable OC increases is more effective than leaving them uncertain; for instance, a guaranteed $5 increase in daily OC is preferable to letting drivers guess about a random increase between $2.5 and $8.5.

Today’s societies are characterized by a reliance on privately-owned vehicles, or “automobility”. In this context, electric vehicles (EVs) are essential to achieve global climate targets, but few studies investigate the relationship between EVs and incumbent automobility. This study examines if automobility shapes consumer preferences for EVs by analyzing a survey and stated choice experiment applied with 2,555 Canadian new car buyers. We implement a scale exploring consumer engagement with automobility and identify seven constructs through factor analysis. Using regression analysis and a latent class model, we find significant associations between automobility engagement and EV preferences. For example, “Driving Enjoyment” and “Environmental Concern about Car Use” are associated with a preference for EVs, while “Car Empowerment” is associated with a preference for conventional vehicles. We conclude that EVs have a reformist relationship with automobility, potentially continuing certain aspects of automobility at a consumer level while being perceived to lower automobility impacts.

As part of Canada’s commitment to net-zero greenhouse gas (GHG) emissions by 2050, Canada has set a zero-emission vehicle target of 35% of new heavy-duty (Class 8, 15+ t gross vehicle weight) truck sales by 2030 and near 100% by 2040. To assess the implications of these targets, a stock and flow model was combined with a vehicle-kilometre travelled model to quantify the changes required to transition from diesel vehicles to battery electric (BEV) and fuel cell electric vehicles (FCEV) in the province of Alberta. Given the BEV and FCEV vehicles and the supporting infrastructure that are available today, the 35%-by-2030 target was assessed to not be achievable. However, a target of 95% of new vehicles sales by 2040 could be achieved if work began immediately to design and build the necessary infrastructure, especially in providing cost-effective, low GHG hydrogen along critical corridors to support long haul transport.

This article introduces innovative model addressing the “Drone Routing Problem” within multifloor manufacturing sites. The focus aims on developing a strategy to minimize energy costs and reduce delivery times amidst variable spatial conditions. Factors such as facility architecture, dynamic production changes, and urban industrial infrastructure are analysed. The study incorporates environmental aspects, exploring the eco-efficiency of drone-based logistics in industrial settings within the context of sustainable development, city logistics data collection processes, a comprehensive understanding of effectiveness in the contemporary multifloor manufacturing complexes. This research highlights new perspectives for internal logistics optimization with drones while aligning environmentally conscious practices in sophisticated urban industrial infrastructure. The solution may significantly minimize the share of vehicle fleet in the area of production facility. Presented process may significantly reduce the level of traffic congestion in the cities where such production facilities are located, and may also become one of the elements promoting sustainable development.

Decarbonising the land transport sector: Pathways towards enhanced global governance

This article investigates the possible role of global governance in transforming land transport towards decarbonisation. While this transformation faces several barriers, international institutions could help to address these through fulfilling several governance functions: (1) guidance and signal, (2) rules and standards, (3) transparency and accountability, (4) knowledge and learning, (5) means of implementation, and (6) orchestration and coordination. Our analysis shows that international institutions have failed to fully harness their potential, leading to governance gaps. Accordingly, we propose reforms for several institutions, including how the United Nations climate regime can help orchestrate activities by other international institutions. Specifically, we explore options for (1) developing an authoritative roadmap and transport-specific net-zero target, (2) integrating sector-specific targets in national mitigation pledges, and (3) developing sector-specific international reporting. Additionally, we explore the creation of an electric vehicles climate club to phase-out fossil-fuelled vehicles. Methodologically, we apply several qualitative data collection techniques.

Did the German aviation tax have a lasting effect on passenger numbers?

The taxation of aviation is a frequently discussed component of governments’ efforts to mitigate greenhouse gas emissions. This study examines the impact of the German aviation tax on passenger numbers during the period 2011–2019 using five panel data estimators and a Specification Curve Analysis (SCA) to assess the robustness of the results to changes in the specifications of the econometric model. Employing five base models, we find that the tax induced a 6–11% reduction in the number of passengers departing annually from Germany in the first two years after implementation. For later years, estimated effects are more ambiguous. The SCA, comprising 175 alternative specifications, corroborates our main findings while showing a slightly wider range of effect sizes, especially on the upper bound. The results show that the choice of econometric method can affect research outcomes, especially for the fourth year of the tax and onward.

Clarifying CO2 emissions and driving factors of private cars is crucial for China’s transport sector to achieve ‘dual carbon goals’. While there are significant regional differences in China’s private vehicle emission levels and driving forces, current analyses of private vehicle CO2 emissions and driving forces rarely consider the inherent differences in urban development. This study used a bottom-up method to develop a CO2 emission inventory for city-scale private car sectors and employed the LMDI model to assess CO2 emission drivers. Predictions for the peak of private cars in Chinese cities before 2035 were made. Results indicated that 49.5 % of cities reached peak emissions by 2020, with the increase in new energy vehicles significantly reducing emissions. Super-large cities often had a minimal impact on emissions growth. The increase in per capita stock was the primary driver of emission growth (+99.84 %), while energy consumption reduction was the most effective factor in emission reduction (-22.84 %). With current policies, China’s private car section was expected to reach carbon peak around 2025, with over 76 % of cities achieving carbon peak.
