Sources: Vehicular emissions, industrial emissions, construction dust, biomass burning (including stubble burning), domestic cooking, power plants, waste burning.
Pollutants: Particulate Matter (PM2.5, PM10), Nitrogen Oxides (NOx), Sulfur Dioxide (SO2), Carbon Monoxide (CO), Ozone (O3), Lead, Ammonia, Benzene.
Health Impacts: Respiratory diseases (asthma, bronchitis, COPD), cardiovascular diseases, lung cancer, premature deaths, reduced life expectancy, neurological disorders.
Environmental Impacts: Acid rain, smog formation, reduced visibility, damage to crops and ecosystems, contribution to climate change.
Monitoring: National Air Quality Monitoring Programme (NAMP) and Continuous Ambient Air Quality Monitoring Stations (CAAQMS) by CPCB.
Indices: Air Quality Index (AQI) to communicate air quality status to the public, categorizing pollution levels from 'Good' to 'Severe'.
Management Strategies: Emission standards for vehicles (e.g., BS-VI) and industries, promotion of public transport and electric vehicles, cleaner fuels, dust control measures at construction sites, waste management, crop residue management, green infrastructure development.
Policy Frameworks: National Clean Air Programme (NCAP), Graded Response Action Plan (GRAP) for NCR, and various state-level action plans.
Technological Solutions: Smog towers, air purifiers (limited effectiveness on a large scale), advanced emission control technologies for industries and vehicles.
International Context: India is a signatory to various international conventions related to air pollution and climate change, such as the Paris Agreement.
This timeline traces key legislative, policy, and judicial interventions in India's journey towards air quality management, highlighting major milestones and recent developments up to 2026.
India's air quality management framework evolved from specific acts to comprehensive legislation following industrial growth and environmental disasters. Recent years have seen a shift towards programmatic approaches and regional coordination, driven by persistent pollution challenges in urban centers like Delhi-NCR.
