Many global transport sector decarbonisation studies assert that it is difficult for the transport sector to decarbonise and to contribute its proportional share to the ambitious climate targets set by the Paris Agreement. We challenge this argument by establishing that deep decarbonisation is possible in the transport sector, through original research that is anchored in a global meta-analysis of long-term transport sector emission pathways from over 500 bottom-up modelling estimates from 81 countries, rather than relying on aggregated regional data and modelling efforts. First, we translate the aspirational 1.5-degree Celsius (1.5DS) target to an indicative 2050 transport sector emission target of 2 GtCO 2 , based on proportional downscaling of existing economy-wide 2DS studies to a transport-specific 1.5DS target. We then compare this with mitigation potential derived from the aggregation of bottom-up estimates for business-as-usual growth and low-carbon scenarios from

In low income countries (LICs) in Africa and Asia per capita transport greenhouse gas emissions are relatively low but are expected to grow. Therefore, a substantial reduction in projected increases is required to bring emissions in line with long-term global climate objectives. Literature on how LICs are integrating climate change mitigation and sustainable transport strategies is limited. Key drivers of transport policy include improving accessibility, congestion, air quality, energy security, with reducing greenhouse gas emissions being of lower priority. This paper assesses the current status, feasibility and potential of selected low-carbon transport measures with high sustainable development benefits that can be implemented in the short to medium term, so- called ‘quick wins’. It examines to what extent ten such quick wins are integrated in climate change strategies in nine low- and middle-income countries in Africa and South Asia. The research method comprises expert interviews, an online questionnaire survey of experts and policymakers in the focus countries, and a review of literature and government plans. Results indicate that sustainable urban transport policies and measures are considered high priority, with vehicle-related measures such as fuel quality and fuel economy standards and electric two- and three-wheelers being of key relevance. In existing national climate change strategies, these quick wins are integrated to a certain extent; however, with better coordination between transport and energy and environment agencies such strategies can be improved. A general conclusion of this paper is that for LICs, quick wins can connect a ‘top-down’ climate perspective with a ‘bottom-up’ transport sector perspective. A knowledge gap exists as to the mitigation potential and sustainable development benefits of these quick wins in the local context of LICs.

There is a growing public transport crisis in India, with a tremendous increase in the number of private vehicles. Many public bus corporations are operating with net financial losses and rely on government subsidies to keep operations going; therefore, investment in new buses and technology upgrades is rare. Of the various expenditures that bus corporations incur, fuel costs account for 30 percent. There is a strong need to improve fuel efficiency of buses to not only improve the financial viability of the bus companies but also to reduce their environmental and related health impacts. This study analyzes data on more than 500 buses from 3 leading bus corporations in India and identifies measures that can be implemented to improve fuel efficiency and reduce emissions.
