In a notable advancement towards cleaner air, India has achieved a remarkable 19.3% reduction in particulate pollution for the year 2022, according to the latest Air Quality Life Index (AQLI) report. This significant improvement has added an average of 51 days to the life expectancy of Indian citizens. The study, conducted by the Energy Policy Institute at the University of Chicago (EPIC), underscores the impact of favorable meteorological conditions and innovative policies on air quality.
Overview of Air Quality Improvements
India’s progress in reducing particulate pollution is a notable development in environmental health. According to the AQLI report for 2024, the reduction in particulate matter—specifically PM2.5—has been substantial, positioning India as a global leader in this area, only surpassed by Bangladesh. This decline has had a tangible impact on public health, with an estimated increase of 51 days in life expectancy for the average Indian.
PM2.5 levels, which measure fine particulate matter in the air, were reported at approximately 9 micrograms per cubic meter in 2022, marking a 19.3% decrease from the previous year. This improvement is attributed primarily to favorable meteorological conditions and a reduction in thermal inversions—weather phenomena where warm air traps cooler air near the surface, exacerbating pollution levels.
Key Areas of Improvement
1. Regional Highlights: The AQLI report reveals that the most significant reductions in particulate pollution were observed in specific districts across West Bengal and Jharkhand. In Purulia and Bankura districts of West Bengal, and Dhanbad, Purbi, Paschim Singhbhum, Paschim Medinipur, and Bokaro districts in Jharkhand, PM2.5 concentrations decreased by over 20 micrograms per cubic meter. This decline highlights the success of localized efforts and policy interventions in improving air quality.
2. Northern Plains: The northern plains, historically the most polluted region in India, saw a 17.2% reduction in particulate levels in 2022. Despite this improvement, residents in this area still face significant health risks, with an estimated loss of 5.4 years in life expectancy if current pollution levels persist. However, if the trend of decreasing pollution continues, life expectancy in the northern plains could see an increase of 1.2 years.
Impact of National Air Quality Programs
1. National Clean Air Programme (NCAP): The National Clean Air Programme (NCAP), launched in 2019, aims to tackle air pollution through targeted reductions and improved air quality management. The AQLI report indicates that districts covered by the NCAP experienced a 19% decline in PM2.5 concentrations, compared to a 16% decline in areas not covered by the program. Despite this, districts with the highest reductions in particulate matter were not necessarily part of the NCAP framework, highlighting the need for broader implementation and support.
2. Future Targets: The NCAP targets a 20-30% reduction in particulate pollution by 2024, based on 2017 levels, with a revised goal of a 40% reduction by 2026. As of 2022, districts with non-attainment status, which consistently failed to meet national air quality standards, saw an 18.8% reduction in pollution. This progress has added approximately 10.8 months to the life expectancy of residents in these areas and four months to the national average.
Policy Innovations and Public Health
1. Gujarat’s Market for Particulate Pollution: In 2019, Gujarat introduced the world’s first market for particulate pollution, which has significantly reduced pollution levels in Surat and is expanding to other cities and states. This innovative approach demonstrates that economic and environmental goals can be achieved simultaneously, providing a model for other regions grappling with air quality challenges.
2. Pradhan Mantri Ujjwala Yojana: The Pradhan Mantri Ujjwala Yojana, a clean cooking program, has been instrumental in reducing emissions from the residential sector. By promoting the use of cleaner cooking technologies, this scheme has contributed to a noticeable decline in air pollution related to household activities.
3. Decreased Diesel Use: The reduction in transport-related emissions is partly attributed to the decreased use of diesel in the transport sector. This shift has been beneficial in lowering overall pollution levels and improving air quality across urban and rural areas.
Challenges and Recommendations
1. Remaining Pollution Levels: Despite significant progress, India still faces challenges in meeting the World Health Organization’s recommended annual PM2.5 concentration standard of 5 micrograms per cubic meter. Over 40% of the population breathes air that exceeds this standard, underscoring the need for continued efforts to improve air quality and public health.
2. Call for Enhanced Standards: The AQLI report emphasizes the importance of revising national air quality standards to align with WHO guidelines. Enhanced regulations and stronger enforcement are necessary to further reduce pollution levels and safeguard public health.
3. Political Will and Implementation: Successful implementation of air quality management strategies requires political will and commitment. The report highlights that while India has the tools and technologies needed to address air pollution, sustained effort and political support are crucial for achieving long-term improvements.
