This study is part of a larger research project on Promoting Low-Carbon Transport in India, a major initiative of the United Nations Environment Programme (UNEP), referred to as the Low Carbon Transport (LCT) project in this publication. The overall context in which the LCT project has been undertaken is the critical role of the transport sector in reducing greenhouse gas (GHG) emissions. India is currently the fourth largest GHG emitter in the world, although its per capita emissions are less than half of the world’s average.
