Neighbourhood News Desk/Avi Arya: An emissions inventory that was conducted by the Pune-based SAFAR (System of Air Quality and Weather Forecasting Research) under the MoES (Ministry of Earth Sciences) has found out that vehicles and industries are considered the biggest contributors to pollution in Delhi.
Emissions from both transport and industrial sectors have gone up by 40% and 48%, respectively. Surprisingly, windblown dust that is often blamed for pollution in Delhi is also reduced by 26% between 2010 and 2018.
Study shows that due to an increase in traffic that lowers the vehicle’s speed might be the reason for the reduction of windblown dust that gets exacerbated when vehicles speed on roads. The 64% reduction in emissions from biomass burning in the residential sector can be linked to “penetration of LPG in slum areas, street vendors, household and others”.
This inventory states that heavy commercial vehicles and private four-wheelers have emerged as the main pollution sources in Delhi. While the industrial emissions contributed to only 18.6% of PM 2.5 emissions in Delhi, the inventory for NCR shows the contribution from industry is about 22.3%.
Gufran Beig, lead author of the study and project director of SAFAR said, “Industrial emissions increased by 48% in 2018 compared to 2010, mainly due to increase in industrial activities in fringe areas of Delhi and not inside Delhi. Most industries were shifted out of Delhi in the 90s”
