Rapid urbanization and rising income per capita have fueled transportation growth in emerging countries. Transportation contributes nearly 10% of India's GHG emissions. This study provides the latest North Indian transportation emission inventory for six compounds from three vehicle modes using five fuels for 2010–2020. For roadways, emission inventory is constructed using Intergovernmental Panel on Climate Change (IPCC) bottom-up approach, whereas IPCC's top-down emissions approach is utilized for railways and airways. Energy production back calculations are used to estimate electric vehicle emissions. North Indian transportation emitted 39 Tg of CO2 in 2010 and 67.6 Tg in 2020, at 6% Compound Average Growth Rate (CAGR). Railways contributed 1.1% and airways 3.6% of total CO2 emissions, while roads contributed 95.2%. HDV and LCV emit the most CO2, CO, and NOx, while 4W’s and 2W’s emit the most CH4 and NMVOC. CNG vehicles emit the least CO2, while diesel vehicles emit the most. EVs emit 148.1 Gg of CO2 in 2020, a −13% CAGR. Electric locomotives replaced diesel, but non-renewable resources generate most electricity, so railway emissions remain high. Infant > children > adult was the order of intake fraction discovery. The inventory suggests North Indian transportation emission control strategies.
