“Mobility crisis”: These are the words used by Anumita Roychoudhury, the executive director of Delhi’s Centre for Science and Environment, to describe the growing pollution in India, especially in large cities like Delhi, as a result of the dramatic increase in the use of motorized vehicles in the past two decades. Although the population of Delhi and its surrounding cities more than doubled (to twenty-two million) between 1991 and 2011, she points out that registered cars and motorbikes increased fivefold, to eight million.1 Th is growth, along with increased but poorly regulated construction, underinvestment in public transport, and local and national policies that privilege automobiles at the expense of other forms of transport, has resulted in pollution rates that are now, according to a World Health Organization report, the worst in the world.2
