A methodology for evaluating environmental co-benefits in the transport sector: application to the Delhi metro

Doll, Christopher N. H.
Balaban, Osman
This paper presents a methodology to measure the environmental co-benefits of transport initiatives, defined here as carbon emissions in conjunction with local air pollution. An evaluation tool was developed and then tested on the case of the Delhi metro. The metro is an extensive rail project spanning the Indian capital, which is also the world's first rail based Clean Development Mechanism (CDM) project. However, it has also been a flashpoint in urban policy-making in the city in recent years. This analysis identifies the co-benefits based on the current situation as well potential co-benefits based on increased ridership and altering mode share contributions. The paper then discusses the challenges faced in the quantification process and the practical implications of achieving increased co-benefits. The paper highlights issues of data quality as well as data access, whilst identifying that factors peripheral to the project itself can have a critical effect in achieving co-benefits from large scale transport infrastructure projects in developing countries.


Institutional framework for urban development with co-benefits: the Indian experience
Doll, Christopher N. H.; Dreyfus, Magali; Ahmad, Sohail; Balaban, Osman (Elsevier BV, 2013-11-01)
The co-benefits approach has been proposed as a means for mainstreaming environmental concerns into urban development, especially in developing countries. This paper reviews the Indian situation setting out the urban-environmental challenge. National policies related to urban development, climate change and specific sectors are examined and then, with the aid of cases, analysed to understand the strengths and weaknesses of generating co-benefits in the world's second most populous country.
An effective framework for life cycle and cost assessment for marine vessels aiming to select optimal propulsion systems
Jeong, Byongug; Wang, Haibin; Oğuz, Elif; Zhou, Peilin (Elsevier BV, 2018-06-20)
By adopting the concept of modularity, this paper introduced an optimal framework which facilitates life cycle assessment and life cycle cost assessment, thereby supporting rapid and reliable decision-making in the marine industry. The benefits of the proposed framework were discussed through two case studies where the optimal configurations of marine propulsion systems were determined from the economic and environmental perspectives. First, the performance of a short-route ferry using the hybrid system was...

The objectives and methodology of the EU-funded research project HYVOLUTION devoted to hydrogen production from biomass are reviewed.
A novel hybrid method using fuzzy decision making and multi-objective programming for sustainable-reliable supplier selection in two-echelon supply chain design

Recently, large companies have shown a growing tendency to enhance the reliability and sustainability of their supply chains to increase customers' satisfaction in terms of on-time fulfillment of demands and to be compatible with environmental regulations. Therefore, finding the best approaches to achieve companies' goals is a crucial concern in supply chain management, and the majority of organizations prefer to cooperate with reliable and sustainable companies. In designing a supply chain, the supplier se...
Life cycle and economic assessment of a solar panel array applied to a short route ferry
Wang, Haibin; Oğuz, Elif; Jeong, Byongug; Zhou, Peilin (Elsevier BV, 2019-05-10)
This paper was to investigate the potential benefits of solar panel systems if applied for obtaining propulsion power of a short route ferry operating in the Marmara Sea. The life cycle assessment was applied to evaluate the long-term environmental impact of the solar power systems on-board in replace of conventional diesel engine systems. The cost and benefit of such systems were evaluated through the economic assessment where the life cycle cost relative to installation, operation and recycling of the sol...
