Estimation of Carbon Dioxide Emission from Vehicles in Lucknow

Emissions of greenhouse gases (GHGs) into the atmosphere have led to the rise in temperature of the planet. Increase in the concentration of GHGs is due to the emission from natural and anthropogenic activities. Various pollutants are emitted from the exhaust of vehicles including carbon dioxide (CO₂) which is a greenhouse gas, this has led to an increase in the concentration of anthropogenic CO₂ in the atmosphere. This study is conducted to determine the emission of CO₂ from the vehicles at four major roads of Lucknow. Traffic count survey is conducted to determine the traffic volume and its composition. Central Pollution Control Board (CPCB) emission factor is used for the estimation of emission. The result of traffic survey count shows that bikes are the major share of vehicles with 39% at Kanpur road, 47% at Faizabad road, 32% at Prayagraj road, and 37% at Sitapur road. The total concentration of CO₂ emitted is estimated to be 491,937 g/km/hr, 291,640 g/km/hr, 404,662 g/km/hr and 252,443 g/km/hr at Kanpur road, Sitapur road, Prayagraj road, and Faizabad road, respectively. Petrol cars and diesel cars are the major sources of CO₂ emission at all sites.
