Why in News?

Commission for Air Quality Management in National Capital Region(NCR) and Adjoining Areas has invoked an eight-point action plan aligning with Stage-IV of the Graded Response Action Plan (GRAP), aiming to avert any additional decline in the region's air quality.

What is the Eight Point Action Plan as per Stage-IV of GRAP?

• Prohibiting the entry of truck traffic into Delhi, except for those transporting essential goods and services, along with LNG/CNG/electric trucks.
• Restricting non-Delhi-registered Light Commercial Vehicles (LCVs) to enter Delhi, unless they are EVs/CNG/BS-VI diesel, except for essential service carriers.
• Banning the operation of Delhi-registered diesel Medium Goods Vehicles (MGVs) and Heavy Goods Vehicles (HGVs), except for those transporting essential items.
• Imposing a prohibition on construction and demolition (C&D) activities in linear public projects like highways, roads, flyovers, power transmission, and pipelines.
• Advising NCR State Governments and GNCTD to transition physical classes for grades VI to IX, XI to online mode.
• Directing NCR State Governments/GNCTD to consider allowing 50% capacity in public, municipal, and private offices, with the remainder working remotely.
• Empowering the Central Government to decide on work-from-home protocols for employees in Central Government offices.
• Encouraging State Governments to contemplate additional emergency measures such as the closure of educational institutions, non-essential commercial activities, and implementing an odd-even vehicle registration number scheme.

What are the Main Causes and Sources of Air Pollution in Delhi-NCR Region?

• Stubble burning: Burning crop residue by farmers in the nearby states of Punjab, Haryana and Uttar Pradesh though significantly reduced but still stands as a primary cause of heightened air pollution brought by north-westerly winds in the national capital during October and November.
  • According to SAFAR, stubble burning contributed 25% to Delhi's pollution in 2021.
    • SAFAR stands for System of Air Quality and Weather Forecasting and Research. It is a national initiative introduced by the Ministry of Earth Sciences (MoES) to provide location-specific information on air quality in near real time.
• Vehicle Emissions: The vehicular emissions from the large number of cars, trucks, buses, and two-wheelers plying on the roads of Delhi and the NCR are another significant source of air pollution.
  
  • As per a research paper published in the Observer Research Foundation, the transport sector is the main source of PM2.5 emissions in Delhi (28% of all PM2.5 emissions).
• Industrial Emissions: The presence of multiple industries in and around the NCR region releases harmful emissions into the atmosphere. Industries emit various pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, contributing substantially to air pollution.
• Construction Activities: Construction sites, especially brick kilns in the outskirts, generate high levels of pollutants.
  
  • Lack of compliance with environmental regulations, inadequate waste management, and insufficient timelines for construction projects compound the problem.
• Waste Burning and Landfills: Improper disposal of waste, including open burning of garbage and landfill sites, emits harmful gases and particulate matter into the air, significantly affecting air quality.
  
  • Example: The Ghazipur landfill site.
• Geographical and Meteorological Factors: The geographical location of the NCR region, along with specific meteorological conditions such as temperature inversion during winters, contributes to trapping pollutants close to the ground, leading to the exacerbation of pollution levels.
  
  • October 2023 witnessed the highest pollution levels since 2020 in Delhi-NCR, partly due to minimal rainfall.
    
    • Rain typically aids in settling particulate matter and dust, thereby enhancing the Air Quality Index .

Way Forward

• Strict Emission Control Policies: Stricter enforcement of emission norms for industries, vehicles, and construction activities to limit pollutants released into the atmosphere.
• Public Transport and Traffic Management: Encouraging and enhancing the use of public transportation to reduce vehicular emissions. Expanding and improving public transport networks can alleviate congestion and emissions.
  • The recent initiative in Delhi including increased number of electric buses and Delhi Metro’s additional trips is a significant step in the direction.
• Waste Management and Regulation: Strict regulations and effective enforcement in waste management to minimize open waste burning and landfill emissions.
  • Encouraging recycling, composting, and waste-to-energy initiatives to decrease the volume of waste that is openly burnt.
• Crop Residue Management: Addressing crop burning by providing farmers with sustainable and cost-effective alternatives for residue management like Happy Seeder.
  • Incentivizing and promoting these methods can significantly reduce the need for burning.
