MP Alagiyawanna: It became more ok to breathe in Sri Lanka between 2018 and 2021

The minister refers to a ranking index on air quality to claim that Sri Lanka has significantly improved its air quality standing in Asia and in the world between 2018 and the present.

To verify these claims, FactCheck.lk consulted the 2018 and 2021 (latest available) World Air Quality Report (WAQR). The WAQR is an annual publication by IQAir, who operates a platform that reports real-time and historic PM2.5 (fine particulate matter). PM2.5 is an air pollutant that is widely accepted as the most harmful aerosol particles to human health.
The state minister refers to regional rankings in terms of Asia. FactCheck.lk was not able to find such rankings, however, the WAQR reports did provide regional rankings in terms of South Asia and South and Central Asia.

 
The 2018 WAQR reported that Sri Lanka ranked 6th in South Asia and 18th globally on high air pollution levels, with an average PM2.5 concentration of 32.0µg/m³. Meanwhile according to the 2021 WAQR, Sri Lanka ranked 12th in South and Central Asia and 58th globally, with an average PM2.5 concentration of 17.4µg/m³.

This data confirms the state minster’s claim that Sri Lanka’s air quality has improved in both regional and global rankings. Between 2018 and 2021, Sri Lanka’s air quality improved in absolute terms as well; according to the WAQR, the average concentration of PM2.5 in Sri Lanka’s air almost halved in this period.

Therefore, we classify his statement as TRUE.

Additional Note: Despite significant gains in the quality of Sri Lanka’s air over recent years, Sri Lanka has been experiencing extremely poor air quality around the time of the state minister’s statement. A PM2.5 concentration between 55.5-150.4µg/m³, classified as ‘unhealthy’, has been reported in major cities across the island. www.airquality.lk provides Sri Lanka’s only real-time air quality data with technical correction factors applied for enhanced accuracy. 

In partnership with the government, it has air quality data for many Sri Lankan cities, and guidance on protective measures based on air quality.

*FactCheck.lk’s verdict is based on the most recent information that is publicly accessible. As with every fact check, if new information becomes available, FactCheck.lk will revisit the assessment.
