Transport and sustainability
This free course explores transport and the issues of sustainability. Transport plays a critical part of most people's life but it also creates complex issues for sustainability. You will first investigate the concerns with respect to the use of transport energy, which here mainly concentrates upon road transport vehicles. There is then a detailed consideration of road transport technologies, starting with the established technologies of petrol and diesel, before moving on to explore how these can be made more sustainable. This includes a short overview of petrol and diesel engines and how they work. Finally, you will look at the question of how to achieve a move to radically cleaner transport technologies and transport systems for a low-carbon future.

|Section||Content||What to look out for|
|Introduction||Introduction to the free course|
|1 The transport energy challenge||The important role that energy security and shortages play in determining transport policy||Different countries have different needs for transport energy|
|2 Transport's environmental impacts||A consideration of both direct and indirect impacts, focusing on CO2 in the UK from all sources||The differences in energy and emissions due to the transport sector|
|3 Petrol and diesel engines||A recap of why diesel engines and fuels have slightly higher energy efficiency than petrol systems||The growing penetration of diesel into the vehicle market – and how the market continues to change|
|4 Petrol and diesel emissions||Typical emissions of each vehicle under real-world conditions; how different technologies lead to lower impacts||How the total life-cycle emissions for a vehicle are dependent on each stage of the life of a car|
|5 Cleaner conventional car technologies||How hybrid technologies can help to reduce the overall fuel consumption of a vehicle||The limitations of hybrid systems and the variety available to most consumers|
|6 Lower-carbon fuels||An overview of CNG, LPG and biofuel systems for personal cars||Subtle differences between the various generations of biofuels|
|7 Electric vehicles||Information on pure electric vehicles, 'plug-in' hybrids and fuel-cell powered vehicles||The fact that any type of new technology (fuel or battery) requires an abundant supply system to fully establish those vehicles|
|8 Decarbonized transport||An explanation of the decarbonized pathways towards various transport scenarios||The lowest possible tailpipe emissions; the various life-cycle emissions that each technology accrues|
