Air Quality Analysis in Tbilisi

Air Quality Analysis in Tbilisi

On June 11, 2019, EWMI ACCESS and its grantee – The Georgian Alliance for Safe Roads (GASR) presented the comparative analysis of air quality data in Tbilisi. GASR compared the first quarters of 2018 and 2019, focusing on the emission of Nitrogen Dioxide (NO2) and Particulate Matter (PM2.5 and PM10). These air pollutants reduce immunity to lung infections and increase likelihood of respiratory problems.

The air quality data was taken from the Tsereteli Avenue – one of the busiest streets in Tbilisi – using the data from the National Environmental Agency air quality portal and the SMART-AtmoSim Lab of the Tbilisi State University.

The comparative analysis showed that the NO2 contamination has increased from 33% above the acceptable limit (2018) to 58% (2019). Likewise, excess of PM2.5 has increased from 15% to 16%. The CO emissions are below the norm.

It is noteworthy, that the current vehicle Periodic Technical Inspection (PTI) controls only CO emissions (and this pollutant is below the norm). In its current state, the Periodic Technical Inspection of Vehicles that entered into force since 2018 does not look into NO2 and other important pollutants. These are the pollutants that are reduced by catalytic converters. Checking for catalytic converters will become a mandatory part of PTIs in 2020.

EWMI ACCESS and GASR plan to use this data to call for more effective measures to reduce air pollution in Tbilisi and other parts of Georgia, as well as to mobilize public support for more comprehensive PTIs.

Research findings are available here.
