The public transport fleet of more than 900 diesel buses (public and private) and the increasing vehicle population in the City contribute to the usually observed moderate air quality in Coimbatore. More than 70000 vehicles were registered in the year 2015- 16. Based on figures that were estimated in the GHG emissions inventory, prepared under the CapaCITIES project for 2015-16, the transport sector in Coimbatore consumes 60% of total energy consumption in the City, corresponding to 43% of economy wide GHG emissions. Therefore, it is important for the City
to continuously monitor air quality and consider corrective measures to ensure good air quality at all times.
