• Climate change concern can contribute to reduced car use and sustainable mobility. • Those worried about climate change were more willing to live without a car. • Relationship between climate change concern and car use differs based on type of car. • Worry about climate change was strongly related to lower use of a conventional car. • Worry about climate change was unrelated to the use of an electric car. Climate change concern has been linked to climate-friendly behavior, but little is known on whether and how it may promote sustainable mobility. This paper investigates how worry about climate change relates to attitudes and intentions towards the car as well as the actual use of conventional and electric cars in Oslo and Viken in Norway. Findings indicate a relationship between worry about climate change and reduced car use, mediated by mode preferences and willingness to live car-free. Those concerned about climate change were less likely to commute by a conventional car and used conventional cars less both on weekdays and weekends. Worry about climate change was also related to living in a denser neighborhood, preference for travel modes other than the car, and willingness to live car-free. Raising greater awareness of climate change could contribute to climate change mitigation by promoting car-reduced or car-free lifestyles and sustainable mobility. [ABSTRACT FROM AUTHOR]

• We explore the agency for energy efficiency in all major types of ship operations. • How do voyage planning and execution decisions affect energy efficiency? • Commercial decisions matter more for energy efficiency than operational decisions. • Networked agency for energy efficiency limits climate change mitigation potential. • Policymakers should expand regulatory focus to cargo owners to reduce emissions. To mitigate climate change due to international shipping, the International Maritime Organization (IMO) requires shipowners and ship technical managers to improve the energy efficiency of ships' operations. This paper studies how voyage planning and execution decisions affect energy efficiency and distinguishes between the commercial and nautical components of energy efficiency. Commercial decisions for voyage planning depend on dynamic market conditions and matter more for energy efficiency than nautical decisions do for voyage execution. The paper identifies the people involved in decision-making processes and advances the energy-efficiency literature by revealing the highly networked nature of agency for energy efficiency. The IMO's current energy efficiency regulations fail to distinguish between the commercial and nautical aspects of energy efficiency, which limits the ability to mitigate climate change through regulatory measures. Policymakers should expand their regulatory focus beyond shipowners and technical managers to cargo owners to improve energy efficiency and reduce maritime transport emissions.

The environmental problems brought by the shipping industry have drawn the attention of all parties, making it critical to select a fuel system that combines economic and environmental benefits when ordering new ships. This paper narrows down a list of fuels to four high-potential options: LNG, methanol, hydrogen, and ammonia. Based on the dual perspectives of shipowners and the public, this study takes different-sized ships as the object, establishes mathematical models throughout their life cycle, and selects a variety of indicators to evaluate alternative fuels. The findings demonstrate that, in the short term, heavy fuel oil with scrubbers is the most economically advantageous option for all sizes of container ships, but methanol is a desirable alternative when taking into account the social cost of pollutants. Hydrogen might be the ultimate fuel to reduce emissions in the long run when the price gap closes. [ABSTRACT FROM AUTHOR]

• A framework for bridge scour risk management in an uncertain climate future. • A systematic approach to estimating scour risk ratings in different climate scenarios. • Local scour progression is fastest during the initial 48 h of a peak flow event. • Accelerated scour risk progression even in low emission climate scenario (RCP2.6). Riverine bridges are under a substantial threat of scour due to the magnitude and frequency of floods arising due to climate change. Infrequent inspections, inadequate data on foundation depths, and the lack of consideration of hydrologic and climate parameters often result in uncertainties within current scour risk assessments. This paper presents an approach for assessing the risk progression of local scour in peak flow conditions that consider uncertainties associated with location, downscaling of climate predictions, and hydrologic, hydraulic and scour prediction models. A rational scour risk rating based on warning time to failure is introduced that can provide a useful addition to the existing bridge condition indexes. The case study on a set of railway bridges in Southeast England shows that climate change could accelerate the scour risk progression, even in the low-emission scenario. The approach and results form a vital basis for scour risk mitigation and climate adaptation planning. [ABSTRACT FROM AUTHOR]

This paper presents an integrated analysis of the costs and benefits of carefully constructed scenarios for the electrification of transport in Australia. Scenarios were constructed to responsively meet increased electricity demand, whilst maximising emission reduction, household finances and public health benefits. The scenarios bundle several technologies, including charging infrastructure, electric vehicles, home battery systems, and renewable energy. The fastest, mission-style, adoption scenario can reduce emissions by 9% of the 2030 carbon budget and reduce the loss of life by 24,000 by 2042. In all scenarios, government expenditure is dwarfed by the estimated public benefits, and households are nearly always better off in the medium to long term. Demonstrating the feasibility and advantages of surface transportation electrification in Australia, which presents cross-sections of rural and urban infrastructure, traffic and a large, socially and politically diverse population, provides broadly applicable evidence of the feasibility of electrification in other jurisdictions.

• Sufficiency is an essential pillar of sustainability. • Individual mobility budgets carbon reduction goals more comprehensible. • The perceived fairness is crucial for the distribution individual mobility budgets. • Individual mobility budgets can serve as an indicator for transport justice. Transport justice has two essential dimensions: (1) compensating for inequalities in access to mobility, and (2) mitigating the disproportionately burdensome negative consequences of transport. In light of the urgently needed action regarding climate change especially in the transport sector, measures reducing carbon emissions to mitigate the impact are inevitable. However, policy measures for reaching climate targets should avoid increasing unequal mobility chances. Therefore, there is a need for concepts striving to mitigate both climate impacts and transport injustice. The paper addresses the potential of introducing individual mobility budgets to achieve transport-related climate goals while reducing inequalities in mobility. The concept proposed in this contribution is based on a combination of qualitative and quantitative impact assessment methods including a stakeholder involvement process and transport modelling based on different data sources. The results provide policy recommendations as well as further research requirements, which are already partly addressed iin follow-up projects. [ABSTRACT FROM AUTHOR]
