Rapid urbanisation and accompanying motorisation has created some of the most polluting cities in India and rising demand for oil is leading to higher imports, besides causing more CO2 emissions. The government of India wants to achieve the climate goals through a sustainability approach that simultaneously addresses other environment and developmental challenges. This paper analyses a sustainable low carbon transport (SLCT) scenario based on sustainable strategies for passenger and freight mobility, vehicle technologies and fuel using global CO2 prices that correspond to 2 °C global stabilisation target. The scenarios span from years 2010 to 2050 and are analysed using the energy system model-ANSWER MARKAL. The SLCT scenario has improved energy security (cumulative oil demand lower by 3100 Mtoe), improved air quality (PM 2.5 emissions never exceed the existing levels) and the cumulative CO2 emissions are lower by 13 billion t CO2 thereby showing that achieving development objectives with CO2 co-benefits is feasible.

Papers in this special issue show how transport transitions in Asia may play out in different socio-economic and policy scenarios, including a low carbon scenario equivalent to 2 °C stabilization. Accounting for heterogeneity of national transport systems, these papers use diverse methods, frameworks and models to assess the response of the transport system to environmental policy, such as a carbon tax, as well as to a cluster of policies aimed at diverse development indicators. The analysis shows that CO2 mitigation in a transport system is achieved more effectively by aligning mitigation policies with sustainable development policies and measures such as mandates for mode share and choices such as urban design, information and communication systems, and behavioral measures. Authors therefore advocate policies that target multiple dividends vis-à-vis carbon mitigation, energy security and local air quality. Whereas four papers focus on emissions mitigation policies, one paper examines challenges to adapt fast growing transport infrastructures to future climate change induced risks. Collectively, the papers exemplify a set of policies and measures that can deliver co-benefits, and, also, demonstrate the use of methods, frameworks and models to delineate the optimal mix of such policies and measures.
