The surge in carbon dioxide (CO2) emissions from the transport sector is a growing concern globally, given its enormous impact on environment. According to a report by the International Energy Agency (IEA), about 24% of the global direct CO2 emissions from fuel combustion in 2019, came from the transport sector.
International Transport Forum's Transport Outlook 2019 says that by 2050, the demand for urban passenger transport is set to double. Further, the UN Department of Economic and Social Affairs (UN DESA) estimates that 70% of the world’s population will be urban by 2050, pushing up the demand for passenger transport significantly.
