Bring back CO2 testing for cars, DOTC urged

The order of the Department of Transportation and Communications (DOTC) removing carbon dioxide from the list of gases monitored in motor vehicle emission tests should be made to comply with the Clean Air Act and President Aquino’s National Plan on Climate Change.

Sen. Loren Legarda, chairperson of the Senate oversight committee on climate change, made the assertion on learning the DOTC had removed CO2 from the emission test monitoring list.

Legarda had initially voiced concern when the order was first unveiled by then Transportation Secretary Manuel Roxas.

She pointed out the Clean Air Act provides that the Philippines shall phase out ozone-depleting substances from the atmosphere.

The recently signed National Plan on Climate Change of Mr. Aquino also mandates the pursuit of environmentally sustainable transport measures, including vehicle emission controls and standards setting, the environmental watchdog ANI Kalikasan said in a press statement.

Carbon dioxide is recognized worldwide as the top air pollutant with no less than the Kyoto Protocol underscoring CO2 from motor vehicles as one of the main causes of global warming and climate change. The Philippines is a signatory to the Kyoto


In a statement, ANI Kalikasan reiterated its call to Transportation Secretary Joseph  Abaya to consider the issues of air pollution and climate change and their implications before implementing the department order.

ANI Kalikasan president Macario Evangelista said the DOTC had regressed in its effort to achieve better air quality from its 2005 standard when it required the testing of four gases, namely, hydrocarbons, carbon monoxide, carbon dioxide and oxygen.

The new DOTC order has reverted to testing three gases, dropping carbon dioxide, instead of moving up to six gases to include nitrogen oxide and sulfur oxide in accordance with international standards.

In fact, Evangelista said, the provisions of the order do not reflect the recent technological and policy developments already recognized and being implemented by the Department of Environment and Natural Resources (DENR), the lead agency in the implementation of the Clean Air Act.

Evangelista urged the new Transportation and Communications secretary, Joseph Emilio Abaya, to withdraw, or at least hold in abeyance, the implementation of the order pending further review, public hearings and technical studies by the DENR and private sector stakeholders.

    Loren Legarda is being her usual epal self again. Even without reviving the CO2 testing for cars, many buses and jeepneys would have failed the smoke belching test at present. By banning these smoke belchers from our streets, that alone would already clean much of EDSA’s pollution. The problem is not with new laws or reviving old ones. The problem is with implementation of the existing laws. Instead of embarrassing herself, Loren Legarda should just focus on her real passions — promoting the indigenous garments industry and concocting new dance music. She’s come a long way from being a DJ of Tito, Vic and Joey’s Discorama in the 70s to become a senator. She need not pretend she could be any smarter. It only makes her look more epal.

  • Ornbort Vortingeresdemesus

    What’s the reason for this? 

    • K Fun

      To make Metro Manila air better otherwise we will end up like Shanghai.

      • rey

         then, don’t exhale.

  • farmerpo

    Sabay sabay, huwag tayong huminga. CO2 ang lumalabas sa baga natin. 

  • K Fun

    Putting it back is a step towards a cleaner air.  A better step is to eliminate obvious smoke belching vehicles immediately by putting heavy fines by zones.  This waay if a belching vehicle is caught in one—it can be caught again in another zone thereby making these operators think twice in deploying them.

  • Garo Ungaro

    This is mandatory…in California it’s every (2) years…your car will not be registered until
    they got your computer smog check result…another source of corruptions if not properly

    • Komen To

      In case you didn’t know, we also have emission test here to pass before registration and it’s better than California coz its every year. Now, why do you still see smoke belching vehicles on the streets? Ask the senator

      • Garo Ungaro

        Thanks for the info…so, what is the issue now…another milking cow
        projects from the government????.

      • jerome

         Correct another source of income…How do you think that those old clunkers where able to be registered at first? See those jeepneys and buses that belch smoke at EDSA or even other streets

  • rey

    if all of the philippines do not use fuel for transportation, eat raw food (because cooking requires fuel that burns and emit carbon dioxide) and do not plant rice (because rice paddies emit methane, a gas that has 23 times more global warming potential that carbon dioxide), then we would reduce our contribution to global warming by 0.28%. yet we are the 3rd most vulnerable country to the impacts of climate change. while the great united states of america has yet to ratify the kyoto protocol. we are not even required by the kyoto protocol to reduce our greenhouse gas emissions. in this world, it’s just a choice of how do you want to die.

  • bagombong

    Yes, even in Maryland and Washington DC, every 2 yrs. you need to submit your car for emission , they are very strict when it comes to car pollution …kaya sa Pinas ang loob ng ilong mo nangingitim sa umaga dahil ang hinihinga mo is bad air…if you notice the outside walls the roads when it rains is maitim bec. polluted air…unlike here in US..masyadong corrupt ang sistema natin, at wala yatang  balak ang tao sa gobyerno natin na linisin ang kalikasan, sabagay matatanda na sila at malapit na silang mawala mundo kaya wala na silang pakialam, ang makalaga na ngayon sa kanila ay pera dahil puwedeng umalis sa Pinas at mamuhay sa ibang bansa ang kanilang mga anak kaya may mahalaga na masipsip nila ang kaban ng bayan….get me…  

    • Komen To

      They cannot even clean the government, and you expect them to clean the environment? Lol. Be a senator and receive your millions, then see if you spend it to clean the air

  • padrefaura

    first, clean up the system. while emission testing is good, ginagawang pugad ng corruption lang yan. rigged naman ang halos lahat ng tester, i experienced this first hand. 

  • Komen To

    This is a clear case of EPAL. Try visiting emission testing centers and you will be surprised how they allow smoke belching vehicles to pass the emission test. They turn off the engine, put the gadget inside the tailpipe, position their face near the pipe, smile and voila, a picture is taken. Palibhasa di ka nagko commute kaya di mo nakikita o naaamoy ang usok na binubuga ng mga jeep, track, tricycle, o ilang kotse sa kalye. Pano nakakapasa sa emission tests ang mga yan? Obviously, gatasan lang itong mga emission centers na to, gaya ng mga drug testing centers for drivers license

  • symonwho

    The LTO should fix the corrption attendant to emission testing. Just observe that many PUJs and PUBs which are obviously smoke belching are plying the roads.

    DOE should also ensure that gasoline and diesel sold in the market are within international standards specially sulfur content.

    Most human activities generate CO2 and the best way to reduce is to trap them in trees, ie. plant more trees. Require these gasoline companies to replant based on fuel sold. Same with vehicle manufacturing. For each vehicle sold, they should plant a hundred trees.

    Reduce traffic congestion in Manila since since this adds up to non-productive use of fuel.
    Sen. Legarda should better look at the traffic congestion if she is a true environmentalist.
    Even if all vehicles are compliant but then stuck in EDSA for hours, the volume of exhaust gases will be more.

  • kismaytami

    Asus naman si legarda, UMEEPAL, masulat lang ang pangalan. Ano bang nangyari sa mga pro-nature kuno mong mga kampanya, WALA.

  • Flugie

    The madame senator is clueless on what’s really happening at emission centers and the serious lobbying of some fronts to have the DOTC remove CO2 from the list – and yes, umeepal just like most politicians.

  • zendric anthero culilang

    What’s the point of testing CO2? Fuels(gasoline or diesel) + air = CO2 + N2 + water vapor + other gases(such as SO2)  if combustion is complete. Since our cars cannot totally burn the fuel there are small to large amount of CO, hydro carbons, nitrogen oxide and sulfur oxide. The bigger the percentage of CO2 in flue gas is better since it somehow shows your car is burning the fuel efficiently. To lessen CO2 emission is to minimize burning of anything on earth…

  • speedstream2

    More than anything else, what we really need is honest-to-goodness, consistent and across-the-board enforcement of applicable rules and regulations, and whatever mandatory tests, that involve public safety and health. But then again, we all already know this seems to be an eternally quixotic caveat.

  • NelsonBagatsing

    For me, i like what Loren Legarda’s project, mas ok na magkaroon ng mga test for cars para maging malinis ang air natin. ok sakin yan!

    • JamesCarag

      yeah, para sakin mas maganda yan! ok talaga si loren legarda!

  • CarlosAcantillado

    Mas ok nga ang ganyan..At least wala na masyadong mausok na sasakyan kung sakaling itutuloy ang test na yan..mas maganda yan sa kalikasan..

    • DanielMarquez

      oo naman!!! ayos din sakin yan!!!

  • TinaCarunungan

    Buti pa si ma’am loren merong concern sa environment natin… kaya gustong gusto ko sya.. paran naman maabutan naman ng mga anak ko ang magandang kalikasan ng Pilipinas.

  • lheckie

    sa emission testing center, ilalagay lang ung probe sa tambutso then that would be the reading. pasado na. ganun b tamang procedure kasi ang mga lgu, maglalagay ng emission testing sa kalsada tapos tatapakan ng husto ang silinyadaor mo. i bet maski ung gamit ni senator na vehicle hindi papasa sa ganitong proceure. gagawin lang tong gatasan ng mga lgu’s. wala pa akong nakita na vehicle na pumasa kapag pinara ng ASBU ng kahit anong lgu, kahit 2 years pa lang ang vehicle mo. either maglagay ka o pumunta ka sa city hall para ayusin pero kalalabasan maglalagy ka din sa cityhall. kung seryoso ang mga lgu sa ganyan, bakit hindi 100%, bakit ung trip lang nilang itesting ang tinetest.  ang hirap kay senator, hindi nyo nilalagay ang sarili mo sa sapatos ni juan dela cruz.
