Karnataka third-highest contributor to pollution among southern States
A new study on air quality in South India reveals that Karnataka is the third-highest contributor to regional pollution, with varying levels of pollution export and import across states. The report suggests that domestic, industrial, and open burning sources are the primary drivers of poor air quality in the region.
Why it matters
Provides scientific data to help policymakers develop regional strategies for air quality management in South India.
The study titled ‘Governance Framework for Airshed-Level Air Quality Management in South India’, which quantifies the contribution of the five South Indian States to each other’s pollution levels, has revealed that pollution originating from Telangana (38%) is the lowest, followed by Andhra Pradesh (44%), Karnataka (47%), Tamil Nadu (61%) and Kerala (65%).
As per the Central Pollution Control Board (CPCB) data, major urban regions in South India exceed the recommended annual average particulate matter (PM10). Recognising this, the National Clean Air Programme (NCAP) classifies 25 cities in South India as non-attainment cities (cities that fail to meet the official national ambient air quality standards for PM).
