The IPCC recently published their 1.5 degree C report, indicating that the planet must achieve carbon neutrality by mid-century and virtually all sectors much be fully decarbonized by 2060. Transportation represents a particular challenge. Rising car ownership, freight movement, and air travel patterns will increase CO2 emissions unless strong actions are taken to change this course. A clear pathway of decreasing emissions must be in place by 2030.
Understanding the most promising options at both the micro and macro scale will be critical to making progress. At the micro scale, the potential CO2 abatement and cost from reductions in vehicle travel, modal shift to lower carbon modes, and technology and fuel options must be better understood, particularly in terms of how the options are likely to evolve into the future. At a macro scale, understanding the relative role of these options, how they may interact, what may be optimal combinations, and how policies can achieve these combinations, are greatly needed. The relative potential and cost of options varies with geography, as does political feasibility. Some measures can be overarching and international, but many will be national or local.
This special issue will be a collection of high-quality papers considering future transportation CO2 reduction options on a micro and macro scale. It will include studies of particular mitigation measures, technologies, and fuels, and will include studies that look across the landscape of such options to identify broad, promising strategies. It welcomes original research, reviews, and short communications on the following topics:
New and expected future trends, such as on-demand mobility, changes in freight distribution logistics, and vehicle automation, and how these may affect CO2 reduction
The potential market for electric vehicles, beyond the 0.2% global share they represent today; and their CO2 reduction potential and cost in different applications (2, 4 wheelers, trucks, etc)
The role of hydrogen relative to electrification, its relative costs and benefits, and markets where it may play an important role
The role of advanced biofuels for light and heavy duty futures, considering costs, availability, and net GHG impacts
The potential for the various alternative low-carbon technology and fuels in trucking, shipping, rail and aviation
Modeling efforts that incorporate and compare various strategies, or compare transportation emissions reductions to other sectors
Innovative policies towards achieving specific or combined strategies, within or across jurisdictions
