Metro Manila air quality improved in 2024 due to Euro 4 fuel standards, says DENR
The Department of Environment and Natural Resources (DENR) reported an improvement in the Philippines' air quality in 2024, attributing it to emission-reduction programs including the enforcement of Euro 4 fuel standards since 2016.
Nationwide, the average concentration of Particulate Matter 10 (PM10) decreased by 28.2 percent between 2016 and 2024.
Metro Manila experienced significant improvements, with PM10 levels falling by 17.4 percent and PM2.5 levels by 37.6 percent during the same period.
In 2024, 65 percent of highly urbanized centers complied with ambient air quality standards for both PM10 and PM2.5, surpassing the national compliance target.
Particulate matter refers to tiny particles suspended in the air from sources like vehicles, industry, and construction.
PM2.5 particles, being finer than PM10, pose greater health risks by reaching deep into the lungs and bloodstream.
