A new CREA report identifies Tripura as one of India’s top pollution hotspots. Discover why six Tripura districts exceed PM2.5 limits even during the monsoon and what this means for the Northeast’s air quality and public health.
A startling new study by the Centre for Research on Energy and Clean Air (CREA) has placed Tripura at the center of a growing environmental crisis. Traditionally viewed as a lush, green corridor of the Northeast, Tripura has been identified as one of India’s most persistent air pollution zones, challenging the long-standing perception that the region is immune to the “smog culture” of northern India.
Breaking the Seasonal Pattern
The CREA report reveals a deeply concerning trend: unlike most Indian states where the monsoon rains provide a temporary reprieve by “washing” the atmosphere, Tripura’s air quality remains dangerously poor year-round. The state, alongside Assam, records PM2.5 concentrations that consistently defy the usual monsoon-driven dip.
In most parts of the country, the National Ambient Air Quality Standards (NAAQS) are met during the rainy season. However, six districts in Tripura were found to breach these permissible levels even during peak rainfall months. This suggests that the state’s pollution isn’t just a byproduct of seasonal weather or stubble burning elsewhere; it is rooted in sustained, local emission sources that operate regardless of the weather.
A Data-Driven Wake-Up Call
The study utilized a sophisticated methodology, blending advanced machine learning with high-resolution satellite imagery and ground-level monitoring data. The results were stark:
Tripura features three districts within the top 50 most polluted districts in all of India.
The state sits alongside Assam (which has 11 districts in the top 50) as a primary driver of poor air quality in the Northeast.
Neighboring states like Meghalaya and Nagaland also show widespread non-compliance, indicating a regional “airshed” crisis.
The Human and Policy Cost
Environmental experts warn that persistent PM2.5 exposure—fine particulate matter that can enter the bloodstream—poses a severe threat to public health, particularly for children and the elderly. Beyond health, this chronic pollution undermines Tripura’s rural and urban development goals.
Officials emphasize that the current “city-centric” approach to pollution management is failing. Because the pollution is widespread across six districts, the report calls for airshed-level governance. This means policymakers must look beyond municipal boundaries and address industrial emissions, vehicular growth, and transboundary smoke that lingers in the Northeast’s unique topography.
The Path Forward
The CREA findings serve as a critical wake-up call. To combat this, the report recommends:
Expanded Monitoring: Increasing the number of ground-level sensors to get more accurate, real-time data.
Region-Specific Strategies: Moving away from “one-size-fits-all” national policies to address the specific industrial and geographic factors of the Northeast.

Emission Controls: Implementing stricter mandates on local industries and brick kilns that operate year-round.
As Tripura finds itself firmly on the national pollution map, the transition from “Green Tripura” to a “Gray Zone” can only be reversed through immediate, coordinated legislative action and public awareness.
