Analysis of environmental co-benefits of transportation sub-system of Delhi

Abstract

Urban systems are the engines of economic growth. Urbanisation significantly contributes to economic, social, and physical transformation. This transformation is supported by infrastructure services. The pace of urbanisation and industrialisation of Delhi city has not only burdened transport system but also has produced detrimental impact on human development, environment and urban ecosystem. The basic concept of co-benefits is applied to understand the multiple dimension of transport policy beyond its intended benefit. Authors in this research have quantified the benefits and co-benefits of different implemented policies and technology intervention done by the government from 2001 to 2015 in Delhi, the capital city of India, and have observed that the emissions from all vehicles have been steadily increasing despite sincere efforts done by the planners due to increase in number of vehicles in the city. The paper concluded with plausible findings and strategies for emission reduction, and benefits and co-benefits of Delhi Metro system in the city.
