“…The different papers communicated the type of rail infrastructure in different ways, some reported a fraction of the infrastructure as tunnels, bridges, or at-grade (Morita et al 2013, International Union of Railways 2016). Others reported detailed infrastructure information extracted from construction documents (Chang and Kendall 2011, Lederer et al 2016.…”

“…The UK Bothnia freight rail was the only freight rail case study with a reported 2671 tCO 2 e km −1 embodied emissions (International Union of Railways 2016). Seven light rail case studies were reviewed and their emissions range from 47 to 8475 tCO 2 e km −1 (Chester et al 2012, Lederer et al 2016. The Tokyo light rail line is the extrema (maximum) in the light rail boxplot diagram (see figure 4) with 11% tunnels.…”

This paper investigates the state of knowledge in quantifying the embodied greenhouse gas (GHG) emissions in rail infrastructure and develops a sketch model for estimating the GHG impact of rail infrastructure based on the literature. A literature review identified 22 publications, containing 57 case studies, at least touching on the embodied GHG for different types of rail infrastructure. The cases studies include high speed rail, intercity rail, light rail, commuter rail, heavy rail, freight, and metro rail. The paper examines the GHG impact per kilometre of rail infrastructure reported across the case studies and compares the boundaries, functional units, methods, and data used. Most studies employed process-based LCA for an attributional analysis. The embodied emissions associated with the case studies range from 0.5 to 12 700 tCO 2 km −1 ; much of the variation is dependent on the proportion of the rail line at-grade, elevated, or in a tunnel. However, large ranges in GHG per kilometre remain after controlling for elevated and tunneled distance. Comparing the embodied emissions across the rail types was challenging, due to the large variations in system boundaries, study goals, and inventory methods adopted in the publications. This review highlights the need for standardization across the reporting of embodied GHG for rail infrastructure to better facilitate hot spot detection, engineering design and GHG policy decision making. The statistical model finds that overall ∼941(±168) tCO 2 e are embodied per kilometre of rail at-grade, and tunneling has 27 (±5) times more embodied GHG per kilometre than at-grade construction. The statistical model is based on the findings of published literature and does not explicitly consider function, geometry, specifications, emphasis on whole lifecycle, legislative constraints, socio-economic factors, or the physical and environmental conditions of the construction site.

“…Sanches evaluated the energy and carbon emission of a new metro line in Rio de Janeiro in its life cycle [ 18 ]. Lederer calculated the impact of three measures on reducing the green gas emission of the Vienna metro, and the results show that the effect of the metro is better than other modes of transportation [ 19 ]. Li used the life cycle assessment method to define the system boundary of the Shanghai metro life cycle, and made statistics of the relevant resource input and emission output according to the actual observation data.…”

With the strengthening of environmental awareness, the government pays much more attention to environmental protection and thus implements carbon trading schemes to promote the reduction of global carbon dioxide emissions. The carbon Generalized System of Preferences (GSP) is an incentive mechanism for citizens to value their energy conservation and carbon reduction. Individual travel needs to rely on various means of transportation, resulting in energy consumption. Carbon tax or subsidy can only be carried out after carbon GSP accurately measures individual carbon emissions. The big data acquired from the smart cards of passengers’ travels provide the possibility for carbon emission accounting of individual travel. This research proposes a carbon emission measurement of individual travel. Through establishing the network model of the Nanjing metro with a complex method, the shortest path of the passengers’ travels is obtained. Combined with the origination–destination (OD) records of the smart cards, the total distance of the passengers’ travels is obtained. By selecting the operation table to estimate the carbon emissions generated by the daily operation of the subway system, the carbon emissions per kilometer or per time of passenger travel are finally obtained. With the accurate tracking of carbon emissions for individual travel, the government may establish a comprehensive monitoring system so as to establish a carbon tax and carbon supplement mechanism for citizens.
