The Ancillary Role of CO2 Reduction in Urban Transport Plans

Saving CO2 emissions constitutes one of the most delicate challenges of transport engineering. Coherently with EU and national directives, urban mobility and traffic plans should consider CO2 savings as one of the goals to be reached. In an apparent contradiction, however, the measures generally proposed within urban transport plans seem to operate primarily for different aims, such as decongestion, improvement of public or alternative transport modes, determining an ancillary role of CO2 emissions. Recently, other multidisciplinary forms of planning (e.g., SEAP) have been proposed; which also do not fully consider the complexity of the integrated transport approach. To solve this criticality, this paper presents a two-step method (balance and valuation) for considering CO2 explicitly within mobility plans.
