“…Indian Railways has been actively transitioning from diesel locomotives to electric locomotives, which significantly reduces greenhouse gas emissions. Electrification of railway lines helps in achieving a cleaner and more energy-efficient mode of transportation [56]. The utilization of solar energy is a prominent feature of Indian Railways' climate change adaptation strategy.…”

This study delves into the crucial task of embedding climate change resilience within the sphere of railway infrastructure planning and design in India. As climate change continues to threaten global transportation systems, the creation of robust, sustainable infrastructure becomes indispensable for minimizing its impacts. Initial investigation entails assessing both existing and anticipated climate change scenarios in India, encompassing elements like temperature fluctuations, changes in precipitation, and severe weather phenomena. Following this, the study proceeds to pinpoint the specific risks and vulnerabilities that the Indian railway system stands to confront due to these climatic shifts. A thorough exploration of current adaptation policies and strategies provides a framework to merge these into railway infrastructure planning and design, using a mix of literary review, best practices, and international case studies as resources. The Indian railway network undergoes a meticulous analysis to evaluate its vulnerability, leading to the identification of key adaptation measures like devising new railway tracks, enhancing the existing infrastructure, adopting resilience-based technologies, and implementing nature-centric solutions. The research probes the economic, social, and environmental ramifications of these measures, underlining the long-term sustainability and beneficial impacts on the transportation industry. Expert interviews, stakeholder consultations, and policy analysis culminate in a set of recommendations for policymakers, urban planners, and transportation authorities. These recommendations aim to shape the progression of a climate-resilient railway infrastructure in the light of India's distinct challenges. Such an integration of climate change adaptation strategies contributes towards a more robust and sustainable transportation system. This study enriches the existing body of knowledge on climate change adaptation in transportation, offering valuable perspectives for policymakers, practitioners, and researchers aiming for climate resilience in the railway sector.

Freight Transport Decarbonization: A Systematic Literature Review of System Dynamics Models

et al. 2022

Freight transport decarbonization is currently an urgent challenge. Decarbonization strategies have a specific time to take effect, and it is essential to consider their time dependence. The system dynamics approach is well suited to represent feedback, lagged responses, and the time dependence of decarbonization strategies. We carried out a systematic literature review of system dynamics models in relation to strategies for freight decarbonization to identify the treatment of relevant dynamics of the system within the models. The 50 studies that fulfilled our search criteria were categorized by decarbonization strategies, the external factors needed to support them, and simulated policy instruments. The results show that no model presented a broad view of the system, addressing a limited combination of strategies. Most importantly, system dynamics models do not clarify how time-dependent behavior is determined, which indicates a significant research gap that can be critical for understanding the policy’s urgency and impacts.

Even though the development of renewable energy technologies has been one of the most discussed and research-rich fields of science, and there are many practical and convincing technologies in the field of renewable energy, the path taken by society to shift from the use of non-renewable energy sources to the use of renewable ones has often been slow and unclear. Renewable energy technologies have undergone many improvements. There are several successful and promising examples where installing renewable energy technologies has paid off financially and improved the environment and quality of life. Nevertheless, fossil fuel still dominates or makes up a large proportion of energy production. The research simulates existing, planned, and potential policies to assess the best way to integrate renewable and local energy resources into the energy system by 2030 and in the long term. Policy analysis is carried out for several possible combinations of support measures to assess if it is possible to achieve the set targets in the National and Climate plan by 2030 and reach Climate neutrality by 2050. Such an approach makes it possible to assess the impact of existing policies that create synergies or undesirable side effects and whether they maximize the return on investment from a socio-economic and environmental point of view. In addition, a risk analysis and impact assessment of the proposed policy scenarios are carried out using multi-criteria analysis.
