The analysis of emissions from road transportation and the future of alternative fuels have become critical areas of research in recent years due to the detrimental environmental and health impacts associated with conventional fossil fuel-powered vehicles. This study aims to examine the emissions generated by road transportation and explore the potential of alternative fuels as sustainable and cleaner energy sources for future mobility. The analysis begins by investigating the current state of emissions from road transportation. The study highlights the significant contribution of road transportation to greenhouse gas emissions, including carbon dioxide (CO2), nitrogen oxides (NOx), particulate matter (PM), and methane (CH4). Furthermore, the study delves into the potential of alternative fuels to mitigate the environmental impact of road transportation. It examines a range of alternative fuels, including biofuels, Compressed Natural Gas (CNG), and Electric vehicles to evaluate their emissions characteristics, availability, and technological advancements. The government of India is also closely looking for opportunities to expand these fuels in the Indian market and Indians also intend to explore the opportunities on alternative fuels. There has been a drastic change in the blending percentage of 1.53% in 2013- 14 changes to 8.5% in 2020. We can observe there is a 91% increment in ethanol blending in the few years and as per the government policy target, Inia must achieve 20% Ethanol blending in petrol by 2030. States and UTs like Bihar, Karnataka, Andhra Pradesh, Tamil Nadu, Maharashtra, Delhi, and Uttar Pradesh set aims and targets for Electric Vehicles to contribute to Net- Zero. The major challenges faced by Electric Vehicles are high initial costs, a shortage of charging stations, and extending the charging infrastructure which could cause difficulties.
