But due to the COVID-19 pandemic, it was disrupted for a certain time. The main aim of this study is to compare the carbon dioxide (CO<sub>2</sub>) emission before and during the COVID-19 pandemic for KV based on the motor-spirit (MS) & high-speed-diesel (HSD) fuel consumed by the vehicles. From the fuel sales data provided by Nepal Oil Corporation (NOC), CO<sub>2</sub> emission was calculated as per the Tier 1 approach given in the guidelines provided by the Intergovernmental Panel on Climate Change (IPCC). 14.9% of total fuel sales of Nepal was consumed in KV alone by road transport for fiscal year (FY) 2019/20. KV area produced 9,14,352 tonnes of CO<sub>2</sub> emissions from the transportation sector in the FY 2019/20 from the corresponding 2,92,260 kiloliters of fuels. CO<sub>2</sub> emission had declined by 80.11% after the lockdown was implemented in the valley but later on, till Asar (Mid June – Mid July) it again rose to 65%.</p>}, number={1}, journal={Journal of Innovations in Engineering Education}, author={Paudel, Paranjaya and Sapkota, Sabal and Gyanwali, Khem and Adhikari, Bikash}, year={2021}, month={Mar.}, pages={10–17} }
