While electricity generation is the largest the biggest energy transformation since the contributor, the transportation sector comes Industrial Revolution, during which the use of second, accounting for around 23% of global CO2 fossil fuels drove growth and prosperity, with emissions. global temperature increase implications that Figure 2 looks into the transport sector in a we have only started to understand relatively little more detail, revealing that passenger road recently. This energy revolution will drive the vehicles contribute almost half (45%) of transport world towards a lower carbon, more sustainable CO2, with freight vehicles accounting for another future, with major implications for energy and 30%, so road transport accounts for almost electricity generation, heating, industrial power 75% of the emissions. The aviation and shipping and transportation. Governments, states and industries also release large levels of CO2, each at regions are proposing, and in some cases (such around 11% of global transport-derived emissions, as the UK) committing to, net zero greenhouse with rail being a relatively minor contributor, at gas (GHG) or carbon dioxide emission targets 1%. But to add a little context, these rail CO2 over the coming years. To date, 15 countries emissions are around 0.1 billion tonnes per year, have set defined targets to become net zero the same level as those of Belgium or Austria. economies by 2050 or earlier, with over 50 others, Therefore, it is clear that transport has a critical including Germany and Canada, discussing role to play in the global decarbonisation agenda. when to implement such a target.
