Special Issue Information

Dear Colleagues,

Transport, access to vital services and the ability to move around for work and leisure are key to meeting the UN Sustainable Development Goals. Nonetheless, transport greenhouse gas (GHG) emissions are rising faster than other economic sectors, cancelling out emission reduction gains. In particular, rapid motorisation in developing countries is expected to increase their contribution to total global transport GHG emissions.

Motor vehicles, especially passenger vehicles and heavy-duty trucks, are a major source of air pollutants such as particulate matter (including black carbon), nitrogen oxides and volatile organic compounds that contribute to the formation of ground-level ozone.

The health risks of urban air pollution are serious. Poor air quality increases respiratory ailments such as asthma and bronchitis, heightens the risk of life-threatening conditions (e.g., cancer), and increases the burden on health care systems with substantial medical costs.

The 2015 UN Paris Agreement aims to limit global heating to below 1.5 °C to avoid risks to health, livelihoods, food security, water supply, human security, and economic growth. Far-reaching transitions in transport and other sectors are required to adapt to a changing climate and reduce emissions to avoid further climate change.

While transformational societal change will take time, action is required now to move to low emission mobility to reduce carbon and air pollutant emissions.

Providing a functioning, low emission transport system is a complex endeavour that will require paradigm shifts, systems-thinking, and creative solutions that have the potential for climate and clean air benefits.

The aim of this Special Issue on low emission mobility is to demonstrate the concepts, policy measures, and real-world practice that can contribute to low emission mobility in developed and developing country cities and peri-urban areas.

As part of this Special Issue, we invite high-quality papers that examine a range of issues that will result in a reduction in transport emissions. Topics include but are not limited to:

  • Pricing (e.g., road pricing, yield management in aviation and high-speed trains);
  • Low/alternative fuels such as biofuels and electricity and their challenges;
  • Modal shift and intermodality;
  • Measures to increase occupancy rates/efficiency of vehicles and public transport—for instance, the use of megatrucks or additional vehicles that emit fewer pollutants;
  • Car sharing/promotion of ride sharing;
  • Congestion charging/environmental charges;
  • New vehicle technologies such as autonomous vehicles;
  • Public transport/bus lanes/priority for public transport/bus rapid transport;
  • Pedestrian zones/speed limit restrictions/speed management;
  • Low emission zone restriction by license plate;
  • Bike sharing/dedicated bike lanes;
  • Taxation/subsidies to promote low emission mobility;
  • Public transport, pricing, and regulation;
  • Car parking policies;
  • Regulation and subsidies to bring about cleaner vehicles;
  • Policies/measure that encourage decoupling of the economy and transport growth.

This Special Issue entitled “Sustainable Low Emission Mobility” will address current policy and practice in this area to improve urban air quality, reduce GHG emissions, and foster sustainable mobility in both the developing and developed world.

We encourage the submission of contributions that adopt interdisciplinary approaches from around the world.

Micromobility service systems have recently appeared in urban areas worldwide. Although e-bike and e-scooter services have been operating for some time now, their characteristics have only recently been analyzed in more detail. In particular, the influence on the existing transportation services is not well understood. This study proposes a framework to gather data, infer micromobility trips, deduce their characteristics, and assess their relation to a public transportation network. We validate our approach by comparing it to similar approaches in the literature and applying it to data of over a year from the city of Aachen. We find hints at the recreational role of e-scooters and a larger commuting role for e-bikes. We show that micromobility services in particular are used in situations where public transportation is not a viable alternative, hence often complementing the available services, and competing with public transportation in other areas. This ambivalent relationship between micromobility and public transportation emphasizes the need for appropriate regulations and policies to ensure the sustainability of micromobility services.

The inland navigation sector makes a significant contribution to the growth of the global economy as well as to climate change due to pollutants emitted by diesel engines. NOx emissions are very high in port areas where, due to traffic, the ships run at idling regimes. Selective catalytic reduction (SCR) represents one of the most suitable technologies, in terms of cost effectiveness, but does not perform well if the temperature during vessel operation is lower than 180 °C. Microwave technology can support preheating of the ceramic core of SCR in order to increase the temperature towards the optimal interval for the best NOx reduction. Research has focused on coupling a magnetron head to a SCR device in order to evaluate to what extent the technology can meet the requirements of Stage V of the European Directive related to NOx emissions. Measurements of NOx emitted have been performed on engines with 603.5 kW nominal power and 1500 rpm that operate at a lower engine speed (700–1200 rpm) and output power (58–418 kW). The values recorded for emissions using microwave heating of ceramic core of SCR have decreased by 89% for a constant load of engine and idling engine speed. Full article

A well-thought-out strategy for shaping the transport of the future is a challenge for countries and integration groups. The answer to which modes of transport should become a priority in the context of incurred and planned investments should largely depend on their observed and forecasted environmental impact. This paper focuses on the scope and content of EU macro-regional strategies. The main objectives of the study were to identify common assumptions and differences between the Adriatic and Ionian Region and the Baltic Sea Region in terms of sustainable transport and provide a critical assessment of the EU Strategy for the Adriatic and Ionian Region (EUSAIR) and the EU Strategy for the Baltic Sea Region (EUSBSR) compliance with the assumptions of the White Paper on Transport, as well as the attempt to answer the question of which modes of transport should be prioritized by the analyzed macro-regions, making transport decarbonization one of their main goals. It is possible to state that the assumptions of both the strategies of the macro-regions seem to be partially consistent with the White Paper on Transport vision. However, the emphasis of the macro-regions on the development of maritime transport is somewhat omitted in the White Paper. Among the countries of both areas (EUSAIR, EUSBSR), estimates showed a statistically significant (p < 0.05) positive impact on the volume of loads transported by road transport. An increase in the volume loads by 1% resulted in an increase in air pollution by 0.446% (EUSAIR) and 0.728% (EUSBSR). The elasticity of air pollution, regarding loads’ road transport changes, was the highest compared to other transport modes in the studied areas. This proves the highest emissivity of road transport. In the EUSAIR countries, an increase by 1% of the volume of transport by railway resulted in a decrease in air pollution, with emissions of greenhouse gases decreasing by 0.063%. Considering the analyzed documentation, reports, strategies, and assumptions, it seems right to clearly emphasize the role of rail transport in the decarbonization of transport. According to the authors, mainly, this branch of transport can significantly reduce the emission of gases into the atmosphere and thus contribute to the so-called “green deal”. However, many activities must be undertaken for this to happen, not only investment ones. First of all, it is worth paying attention to the coherence of regional strategies with the European transport development plan contained in the White Paper. Full article
