Approaches and Techniques for Modelling CO₂Emissions from Road Transport

Abstract

Transport accounts for around a quarter of CO 2 emissions globally. Transport modelling provides a useful means to explore the dynamics, scale and magnitude of transport-related emissions. This paper explores the modelling tools available for analysing the emissions of CO 2 from transport. Covering a range of techniques from transport microsimulation to global techno-economic models, this review provides insights into the various advantages and shortcomings of these tools. The paper also examines the value of having a broad range of perspectives for analysing emissions from transport. The paper concludes by suggesting that the broad range of models creates a rich environment for exploring a spectrum of policy questions around the emissions from transport, and the potential for combining modelling approaches further enhances the understanding that can be attained.

Transport Infrastructure Development, Public Performance and Long-Run Economic Growth: A Case Study for the Eu-28 Countries

“…In the context of sustainable development as a desideratum of every society, an important part of the studies [2,[15][16][17]19,40,[65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83] is more complex, being oriented to the environmental and the social dimension from the impact of transport development in relationship with the economic growth. The transport sector accounts for about a quarter of CO 2 emissions globally [84]. Reducing or eliminating carbon dioxide (CO 2 ) emissions and other specific air pollutants from transport supposes implementation of sustainable transport policies, environmental policies, health policies, including economic instruments, and technological innovations.…”

Economic valuation of Well-To-Wheel CO2 emissions from freight transport along the main transalpine corridors

“…A valid solution to address this issue is to use assumptions that are more realistic as well as empirically based assessments of risk, rather than to improve models. Indeed, macro modelling seems to be most suitable when dealing with the international level and long-term evaluations (Linton et al, 2015) even if some interesting implications regarding driving behaviour and micro modelling and mesoscopic modelling (Flügel et al, 2014) may be also considered, but mostly at the urban level. Whichever method policy makers and modellers decide to adopt, they have to consider the vast range of uncertainty related to the economic valuation of CO 2 emissions.…”

A systematic review of the evidence on plug-in electric vehicle user experience

“…Still, if it is assumed that vehicle travel patterns in 'business-as-usual' counterfactuals do not differ greatly from those with the PEVs, the magnitude of PEV mileage shares by actual users suggests that it is reasonable to assume that vehicle-miles are meaningfully substituted from ICEVs. This has implications for energy modelling studies (Anable et al, 2012, Linton et al, 2015 and, more importantly, suggests that, conditional on becoming widespread, PEVs will not be ineffective in reducing greenhouse gas emissions in the usage phase of their lives.…”
