We are pleased to announce that a special issue in Atmospheric Environment with a collection of papers presented in the 23rd Transport and Air Pollution (TAP) conference that took place in Thessaloniki, Greece, from 15th to 17th of May, 2019 is published.
Transport is requested to serve an increasing global population and a growth in world’s economy. This has to be done efficiently, at low cost, and with minimum environmental impacts. New technologies are introduced to serve these needs. For road transport in cities, electrified cars are gaining ground and are expected to become the technology of choice in the medium to long term future. In parallel, lower carbon fuels together with stringent emission control measures are required to meet sustainability targets in the short run. For road freight transport, a similar path is being followed but the energy density of electricity storage introduces additional challenges. Shipping emissions are also put into focus. With the global fuel sulfur cap approaching, the expanded emission control areas and climatic impacts of shipping receiving attention by the regulators, the shipping industry faces increasing environmental challenges.
This special issue aims at collecting latest research findings on environmental challenges that still lie ahead, despite the efforts currently being invested. This primarily includes regulated and unregulated pollutant emissions with the use of latest emission control devices, fuels and propulsion technologies. Trade-offs between air pollutant and greenhouse gases are also of interest. Atmospheric transformation of pollutants, including formation of secondary particles are also welcome. Finally, assessing the impact of policy and infrastructural measures to regulate the activity of certain vehicle or vessel technologies will be considered.
