## ANSWER

## MINISTER  OF  STATE  IN  THE  MINISTRY  OF  ENVIRONMENT,  FOREST  AND CLIMATE CHANGE

## (SHRI BABUL SUPRIYO)

- (a) to (d) The Odd-even scheme has been listed as an emergency (severe+) measure in Graded Response Action Plan, notified on January 12, 2017. The scheme has been implemented  thrice  by  the  Delhi  Government  till  date,  first  during  January  1-15, 2016, then from April 15-30 in 2016 and recently from November 4-15, 2019.

Central Pollution Control Board had conducted an assessment of the odd-even scheme implemented from 1st to 15th January, 2016 in Delhi. The report stated that  while some reduction in air pollution is likely to happen due to odd-even scheme, a single factor or action cannot substantially reduce air pollution levels in Delhi. During 2019, the data is compiled for odd-even period (12 days), pre odd-even period and post odd-even period for the same number of days and presented in below.  The data  does  not  show  much  variation  in  pollution  levels  during  the  odd-even  period. The average concentration and range of concentration for pre  odd-even  period  was higher with respect to odd-even period and the post odd-even period is lower than that of odd-even period.

(e)Several  studies  have  been  conducted  to  identify  major  air  pollution  sources  and  their contributions to ambient air pollution levels in the country. The recent study conducted by TERI  and  ARAI  for  Delhi-NCR  reveals  that  Transport,  Industries,  Agriculture  Burning, Residential,  Dust  [Soil,  Road  &  Construction],  etc  are  the  main  contributors  to  PM10 andPM2.5 concentrations in summer and winter seasons along with meteorological conditions like wind speed, maximum mixing heights, temperature etc. Further, the Central Government has launched National Clean Air Programme (NCAP) in 102 non-attainment cities to tackle the  air  pollution  problem  across  the  country  in  a  comprehensive  manner.  The  objectives interalia  include  augmentation  and  evolving  of  effective  ambient  air  quality  monitoring network  across  the  country  (manual  and  real  time  stations),  source  apportionment  studies, city specific clean air action plans, sectoral interventions etc. Further, ambient air quality is monitored at  793  locations  covering  344  cities/towns  in  28  States  and  7  Union  Territories across the country under National Air Quality Monitoring Programme(NAMP). In addition, there are installed 205  online Continuous  Ambient  Air  Quality  Monitoring  Stations (CAAQMS) in 114 cities including Delhi-NCR, across the country. The Central Government have  constituted  a  high  level  Expert  committee  to  examine,  from  time  to  time,  various technological options to control air pollution. Various Projects have been examined to assess mitigation measures of air pollution in Delhi NCR which inter-alia includes Deployment and Evaluation  of  Wind  Augmentation  &  Purification  Units  (WAYU),  effectiveness  of  dust suppressant for control of dust generated from roads and construction sites.
