Kerala’s Air Quality Rated ‘Satisfactory to Good’: Pollution Board Report

Swift Summary

• Kerala’s ambient air quality currently ranges from “satisfactory” too “good,” as per a report by the Kerala State pollution Control Board (KSPCB).
• The findings were derived from data collected across 40 manual and nine continuous ambient monitoring stations.
• A report dated September 1, 2025, was submitted to the Southern Bench of the National Green Tribunal (NGT) regarding air quality monitoring in the state.
• Efforts include implementing a State Action Plan on Air Quality with guidance from the Central Pollution Control Board (CPCB), following NGT directions.
• Measures adopted:

– industrial units are reducing Volatile Organic compound (VOC) emissions using double seal floating roofs and third-party NABL-accredited monitoring systems.
– Online Continuous Emission Monitoring System (OCEMS) connectivity established by 40 industrial units-13 categorized as highly-polluting industries.

• A source apportionment study is being conducted in Kochi and Thiruvananthapuram by The Energy and Resource Institute (TERI) to identify pollution sources. Funding will be shared between the State government, CPCB, and KSPCB in a ratio of 50:30:20.

Indian Opinion Analysis

The KSPCB’s findings offer an optimistic outlook on Kerala’s overall air quality management, showcasing proactive measures aimed at minimizing industrial emissions. Notably, no areas have been classified as critically polluted-a testament to sustained environmental planning. Initiatives like double seal roof technology reduce vapourization of VOCs while OCEMS installations ensure consistent compliance with regulatory standards.

The source apportionment study led by TERI reflects a collaborative approach toward identifying region-specific pollution contributors in major cities like Kochi and Thiruvananthapuram. This could influence targeted interventions for urban centers notorious for localized pollution spikes due to traffic congestion or waste mismanagement. Moreover,adherence to tribunal directives signals institutional accountability.

While current results are encouraging, sustaining this progress requires constant vigilance over emission controls amid Kerala’s evolving industrial landscape. Broad public engagement coupled with stringent enforcement may strengthen these efforts for long-term gains.
