    As the issue of air pollution in the National Capital Region of Delhi has become a matter of grave concern, the Supreme Court has observed that immediate and effective measures ought to be taken by the concerned governments and implementing agencies in order to curb the pollution levels in the Delhi-NCR region.

    Pursuant to the hearing on 13.11.2021, the Central Government has filed an affidavit to assist the bench comprising the Chief Justice of India NV Ramana, Justice DY Chandrachud and Justice Surya Kant, in this regard.

    At the outset it is submitted that the legislature had enacted the Commission of Quality Management in the National Capital Region Adjoining Areas Act, 2021 and under Section 12, the Commission has been empowered to take all measures, issue directions and entertain complaints, for the purpose of protecting and improving the air quality of the National Capital Region and Adjoining Areas. The affidavit has identified the major contributing factors to air pollution:

    1. Dust management

    2. Industrial pollution

    3. Agricultural stubble burning

    4. Vehicular pollution

    5. Burning of biomass/ municipal solid waste causing pollution and fire in sanitary landfill sites

    6. Bursting of firecrackers

    7. Unfavourable meteorological condition in Delhi NCR region particularly during the winter season.

    The affidavit elaborated on two types of responses to the crisis at hand:

    A. Long term measures

    B. Emergent quick responses

    The Long Term Measures includes:

    a. Ambient Air Quality Monitoring Network

    b. Air Quality Forecast

    c. Measures for controlling Vehicular emission

    ● Quickly shifting from BS-IV to BS-VI fuel standards.

    ● Collection of toll and Environment Compensation charges from commercial vehicles entering Delhi.

    ● Ban on all diesel vehicles older than 10 years and petrol vehicles older than 15 years as per Supreme Court order dated 29.10.2018.

    ● Introduction of BS-IV compliant vehicles across India since April,2020.

    ● Department of Heavy Industry providing subsidies on e-vehicles.

    ● Operationalisation of expressways and highways to divert non-destined traffic.

    d. Measures for control of Industrial Emissions

    ● Ban on use of pet coke and furnace oil as fuel in NCR States since Oct 24, 2017 and use of imported pet coke in the country since July 26, 2018

    ● Shifting of industries to clean fuel and installation of a monitoring system (OCEMS) in red category industries in Delhi-NCR.

    ● Notification regarding SO2 and NOx emission standards issued for thermal power plants.

    e. Measures for control of emissions from construction and demolition waste,solid waste, plastic waste, e-waste, biomedical waste and hazardous waste

    ● Notification of 6 Waste Management Rules issued in 2016

    ● Bio-mining of three dumpsites at Bhalsawa, Okhla and Ghazipur under process.

    ● Notification regarding dust mitigation measures for construction and allied activities.

    ● Advisory issued to DPCC/SPCBs in NCR for using dust suppressants in high emission zones.

    ● Special focus on C&D waste management, bio-remediation of legacy waste dump sites and plastic waste management under Swachh Bharat Mission. Allocation of apx. INR 1.41 lakh crores from 2021-22 to 2025-26.

    f. Measures for control of emissions from firecrackers - Introduction of green crackers, which have 30% reduced PM and gaseous emissions.

    g. Measures for control of emissions from stubble burning - Subsidies provided for establishing custom hiring centres and procurement of crop residue management machinery under the Scheme of 'Promotion of Agricultural Mechanization for in-situ Management of Crop Residue in the States of Punjab, Haryana, UP and NCT Delhi'.

    h. National Clean Air Programme to strengthen ambient air quality network, source apportionment studies, dust mitigation equipment, composting units, infrastructure for non-motorised transport, shifting to clean energy in unorganised sectors, etc.

    i. Comprehensive Action Plan (CAP) - Introduced in Delhi NCR to abate air pollution in a time bound manner.

    As per the affidavit, scientific study indicate that the contributors to the deterioration in air quality throughout the year are:

    A. Industrial pollution

    B. Vehicular pollution

    C. Dust from roads, open areas and construction sites

    D. Biomass burning

    The issue of Stubble Burning

    The affidavit states that there are certain factors which contribute for a limited period of time, but have a larger impact. In this regard, the affidavit provides the illustration of stubble burning (mainly paddy) in neighbouring states which takes place generally for the months of October and November. It is further pointed out that bursting of crackers during Dussehra and Diwali is a contributory factor, and the severity of pollution increases since these two incidents coincide every year. The North-West flowing winds into Delhi NCR and the fact that the peculiar condition of no flow of winds in NCR are also stated to aggravate the impact of stubble burning by encouraging accumulation of pollutants in the region.

    Sectoral Contributions

    The affidavit notes that a scientific study projects the indicative figures to show average sectoral contributions in PM2.5 and PM10 concentrations in Delhi as:


    As per the affidavit the Long term measures have been able to achieve an increase in the number of Good, Satisfactory and Moderate since 2016. The number of 'Good', 'Satisfactory' and 'Moderate' that was 108 in 2016, increased to 227 in 2020 and in 2021 (01.01.2021 to 13.11.2021) it has increased to 197. On the other hand, the number of 'Poor', 'Very Poor' and 'Severe' days had decreased from 246 in 2016 to 139 in 2020 and further to 120 in 2021.


    The Emergent Quick Responses include:

    a. Graded Response Action Plan for Delhi and NCR (GRAP) - Graded measure needs to be taken. A Sub-Committee has been constituted to operationalise GRAP and had passed five orders till dated (18.10.2021, 28.10.2201, 08.11.2021, 12.11.2021 and 13.11.2021).

    Dust Storm - another local factor aggravating pollution

    A member of the Commission (Director, India Institute of Remote Sensing, Dehradun) had informed that apart from stubble burning, the dust storm moving into Delhi-NCR from South-west directions of the Thar desert has also contributed to the adverse air quality raising the PM2.5 and PM 10 levels significantly. However, it was clarified that the effect of the storm has already begun to subside.

    Observations of the Supreme Court on the Commission's meeting and the directions passed therein

    After the Solicitor General, Senior Adv. Tushar Mehta listed out the graded measures to be undertaken by the concerned Governments as suggested by the Sub-Committee, GRAP and emphasised upon by the Commission, Justice Surya Kant pointed out that the Court at present is concerned with urgent relief, whereas the measures being suggested are long term plans. He observed -

    "On the last date CJI pointed out that emergency steps are required to be taken. The suggestions you're pointing at are, this can only be a long term plan."

    Concerned about the more immediate effects, Justice DY Chandrachud directed, "Tell us by the 17th what are concrete measures that you can take to bring about a change in the situation."

    The CJI also directed, "Delhi Government Counsel please clarify what steps you're taking."

    Lamenting that the meeting convened by the Commission did not meet the Court's expectation, the CJI stated, "The way we expected the executive people to respond and come up with a solution hasn't been done. This is unfortunate."

    He further added, "Construction industry, stubble burning etc. are issues. Let the Committee meet and let them discuss these issues and action plan by tomorrow evening...The task force to meet and decide on these issues. Please ask the task force to discuss these specific issues and come back by tomorrow evening. If necessary we can hear tomorrow or the day after tomorrow…"

    Not satisfied with the response in the affidavit, the Bench noted that, "though some decisions were taken by the task force, it has not indicated precisely what steps they are going to take to control these factors which are causing pollution. We direct the Govt. of India to call for an emergency meeting tomorrow to discuss the areas we indicated and to discuss the implementation process."
