90% of vehicles fail emission test: EMB XI

NINE IN 10 vehicles tested for emission by the Environmental Management Bureau did not pass standards set by the Clean Air Act, according to officials.

Speaking at the bi-monthly Connect Health and Wellness Forum at SM Lanang Premier Friday, EMB engineer Melvin Dapitanon said the results of their Nov. 7 joint roadside emission assessment showed that most of the vehicles needed to be checked.

These included around 30 government vehicles.

“On the roadside inspection of the PUJs, most of the diesel engines failed with the emission standard of the Clean Air Act,” Dapitanon said.

The joint emission testing activity tested around 80 vehicles from PUJs, government vehicles, including buses from Bachelor Express. Only one of the 20 buses from the Bachelor Express did not pass the test, as most of their fleet is now already Euro 4 compliant, he said.

The bus tests were conducted last Nov. 9 at the Bachelor motorpool in Ma-a.

Only 10% of the tested vehicles were PUJs, with the rest being private and government vehicles.

During the testing, the vehicles were merely tagged and required to come back for testing this week.

Penalties for the violation of emission standards begin at P1,000 for violators, according to Dapitanon.

The local ordinance, meanwhile, requires vehicles that failed the test to come back within 72 hours to the motorpool of the City Environment and Natural Resources Office (Cenro).

As early as 2015, the Department of Environment and Natural Resources (DENR) had already released standards that regulated the emission of mobile sources of air pollution.

The guidelines were made available via DENR Administrative Order 2015-04.

By 2018, new vehicles will be required to be subjected to Euro 4 standards, which mean lower emissions, less aromatics, and better combustion performance for vehicles.

Meanwhile, the EMB officials reminded authorities that heavy traffic around the city contributes to air pollution, with idle engines not fully burning up the fuel in their vehicles and instead blowing out smoke into the air.

Euro 4 standards include reductions of emissions from 500 parts per million to 50 ppm. Benzene content from fuels should be reduced from 5% to 1%, while aromatics are now limited to 35% from zero limits in the past.

The EMB officials, meanwhile, lauded the effort of the city government to consider using biodiesel in its government vehicles.

However, this should not affect the food sector demand for cooking oil.

In a recent survey, the EMB said that 70% of all emissions come from mobile sources such as PUJs, motorcycles, and tricycles.

The 20% comes from stationary sources, while 10% comes from aerial sources.

Motorcycles and tricycles comprise around 60% of the total vehicles, with only 21% comprising public utility jeeps.

Vehicles such as cars, sports utility vehicles, trucks, and buses each have less recorded emissions.
