Emission testing is a government-mandated process for all motor vehicle owners.
It ensures your vehicle complies with environmental standards by measuring the pollutants it releases.
If your vehicle passes, you’ll receive a Certificate of Emission Compliance (CEC), a primary document for vehicle registration renewal. Without it, you cannot renew your car’s registration.
Emission testing is conducted at LTO-accredited Private Emission Testing Centers (PETCs) and Motor Vehicle Inspection Centers (MVICs).
Testing fees range from Php 430.00 to Php 600.00, depending on the vehicle type and location.
The validity of the test is one year, aligning with your vehicle’s registration cycle.
If you are a car owner planning to renew your registration, emission testing is a non-negotiable requirement.

Why Emission Testing Matters
Every motor vehicle on the road contributes to air quality.
Emission testing controls the release of harmful pollutants like carbon monoxide and particulate matter.
By making sure your vehicle passes emission standards, you help promote cleaner air and a healthier community.
For car owners, it’s not just about compliance—it’s about doing your part for the environment.
Failing to undergo emission testing can delay your vehicle registration, leading to fines or legal consequences.
Who Needs Emission Testing
All registered motor vehicle owners must undergo emission testing before renewing their vehicle registration.
This includes owners of:
- Private vehicles (cars, motorcycles, SUVs)
- Public utility vehicles (PUVs), such as jeepneys, taxis, buses
- For-hire vehicles and company fleets
- Motorcycles and tricycles
- New vehicle imports (prior to registration)
There are exemptions in rare cases—vehicles used for government operations, certain electric vehicles, and hybrids may have separate requirements.
Always check with your local LTO branch for specific guidelines.
What You Need to Bring
For a smooth and quick emission testing process, prepare these documents ahead of time:
- Original and photocopy of your vehicle’s Official Receipt (OR)
- Original and photocopy of your Certificate of Registration (CR)
- Valid government-issued ID
- Previous Certificate of Emission Compliance (CEC), if available
- Tax exemption endorsements or other special permits (if applicable)
Pro tip: Double-check if the testing center requires originals or additional documents.
Missing papers can delay your testing or registration.

How the Process Works
Understanding the process can ease your worries and help you plan your day.
- Arrive early. Some centers operate on a first-come, first-served basis.
- Present your documents. Staff will verify your OR, CR, and ID.
- Initial inspection. Your vehicle undergoes a basic check (lights, horn, etc.).
- Emission test.
- The exhaust pipe is connected to an emission analyzer.
- If the vehicle has an Onboard Diagnostics (OBD-II) port, a scanner is used.
- The test measures pollutants like CO2 and particulate matter.
- Results. You’ll be informed if your vehicle passed or failed.
- Certificate issuance. If you pass, you’ll receive the Certificate of Emission Compliance (CEC).
The entire process usually takes 10 to 15 minutes but can vary depending on the queue.
Costs and Fees Explained
The price of emission testing varies based on your vehicle type and the testing center’s location.
- Standard range: Php 430.00 to Php 600.00
- Bulacan reports: Php 200.00 to Php 300.00 (varies and not guaranteed)

Tips for Passing the Test
Worried your car might fail? Here are practical tips to improve your chances:
- Regular maintenance: Change oil, clean air filters, and ensure engine health
- Warm up your engine: A warmed-up engine burns fuel more efficiently
- Check your tires and brakes: Some tests include basic roadworthiness checks
- Use quality fuel: Poor fuel can lead to higher emissions
- Avoid last-minute fixes: Make repairs days before the test to ensure stability
Failing the test means additional costs for re-testing and potential repairs.
Taking care of your vehicle saves you time and money in the long run.
The Law Behind Emission Testing
The Clean Air Act (Republic Act 8749) mandates emission testing for all motor vehicles.
Enacted in 1999, it aims to reduce air pollution by setting emission limits for vehicles.
The LTO and the Department of Environment and Natural Resources (DENR) are responsible for enforcing this law.
Vehicles that fail to comply with these emission standards are barred from registration renewal.
Simply put, no emission test certificate—no registration.
What Happens If You Fail the Emission Test
Failing isn’t the end of the road, but it does mean extra steps:
- Identify the problem. The testing center should provide details on why your vehicle failed.
- Repair the issue. Bring your vehicle to a trusted mechanic to fix the emission problem.
- Re-inspection. After repairs, you can have your vehicle re-tested.
- Additional fees. Expect to pay for re-inspection (PHP 300.00 for motorcycles/tricycles).
A failed test may delay your registration process, so it’s best to fix potential issues before testing.
How to Save Money on Emission Testing
Being cost-conscious is smart. Here’s how you can save:
- Shop around: Check prices at multiple PETCs
- Ask about packages: Some centers offer discounted rates for multiple services
- Maintain your vehicle: A healthy car is less likely to fail, avoiding re-test fees
- Schedule wisely: Avoid peak months when prices might increase due to demand
- Look for discounts: Some centers offer promos for early-bird or bulk customers (fleet owners)
