“…The LCA reflects the amounts of energy consumption and CO2 emissions at each stage of the life cycle. Some researchers have pointed out that LCA analysis results can lead to reductions in the long-term effects on humans and wildlife, improvement in the quality of products, and decreased amounts of GHG emission (Patra, 2007;Banar and Ozdemir, 2015;Rungskunroch et al, 2021aRungskunroch et al, , 2021bRungskunroch et al, , 2021c. As shown in Figure 3, the life cycle of a HSR network contains four stages: (i) the manufacturing, pre-assembly and logistics stage of where LCE = life cycle of energy consumption; LCCO2 = life cycle of CO2 emissions; ECi = total energy consumption (GJ) in stage i; CEi = total CO2 emission (t) in stage i; i = {manufacturing and pre-assembly, operation, maintenance, demolition}.…”

“…Recent estimates suggested that the construction of ballasted track emits 4.7 t-CO 2 e/km. 19 Although this figure included catenary wires which would not be the case on Canadian freight railways, the distance over which raw materials are shipped for construction in the UK would also be much shorter.…”

The improvement in component service life and railway service reliability has been viewed from an environmental perspective. Delays and train accidents carry enormous costs and greenhouse gas (GHG) emissions potential due to the increased fuel burn and the need to replace heavy equipment prematurely. The use of higher-performance materials, more efficient vehicle design, and modern technology by Canadian railways to reduce service interruptions are presented. Their resulting cost savings not only can provide financial incentives for the continuous optimization of asset utilization but can also lead to significant contributions to the decarbonization of the railway industry. The authors have estimated a total reduction of 2.4 kt-CO2e per year in embodies carbon emissions due to life extensions of wheelsets compared to 2017 levels on a Class 1 railway. System-wide, the rail life extension has resulted in a saving of 8.1 kt-CO2e per year compared to 2017 for the same railway. Compared to 2004, the Canadian railway industry has achieved an annual reduction in embodied carbon emission of 6.7 Mt-CO2e from the reduction in mainline derailments.

“…HSR stations close to central business districts are able to increase job rates because secured and convenient services are offered to workers [21,[38][39][40]. Also, workplaces within walking distance of HSR stations can become an essential criterion for job seekers and new businesses for greener urban innovation towards net zero or even negative emissions [41,42].…”

Socioeconomic Benefits of the Shinkansen Network

High speed rail (HSR) networks have been an essential catalyst in stimulating and balancing regional economic growth that ultimately benefits the society as a whole. Previous studies have revealed that HSR services sustainably yield superior social values for people, especially for adults and those of working age. This has become an advantage of HSR networks over other forms of public transportation. The Shinkansen network in Japan is one of most successful HSR models. Its services bring significant social advantages to the communities it serves, such as shorter travel times and increased job opportunities. Nevertheless, the societal impact of HSR networks depends on many factors, and the benefits of HSR could also be overrated. The goal of this research is to measure the socioeconomic impacts of HSR on people of all genders and age groups. The outcomes could lead to more suitable development of HSR projects and policies. This study investigates data sets for Japanese social factors over 55 years in order to determine the impacts of HSR. The assessment model has been established using Python. It applies Pearson’s correlation (PCC) technique as its main methodology. This study broadly assesses social impacts on population dynamics, education, age dependency, job opportunities, and mortality rate using an unparalleled dataset spanning 55 years of social factors. The results exhibit that younger generations have the most benefits in terms of equal educational accessibility. However, the growth of the HSR network does not influence an increase in the employment rate or labour force numbers, resulting in little benefit to the workforce.
