Fighting Winter Smog: Why the Green Emission Sticker is Essential

Every winter, Punjab’s skyline disappears under a thick blanket of smog — turning daily commutes into health risks. According to IQAir’s real-time monitoring in Lahore, the Air Quality Index (AQI) currently stands at ~165 (“Unhealthy”) with hourly forecasts showing only a slight improvement overnight — dropping to ~159–152 by 9-11 PM and ~149–137 by early morning. PM2.5 concentration remains extremely high at ~76 µg/m³, which is about 15 times higher than the World Health Organization’s safe guideline.

The “Emission Inventory of Punjab 1990–2020” further reveals that the province’s total anthropogenic emission load has reached 7,017 kilotons per year (kT/y), with road transport identified as one of the largest contributors to this growing pollution crisis.

These alarming figures actually represent a drastic drop in Punjab’s air quality. This thick, toxic fog not only reduces visibility but also worsens health conditions and impairs vehicle performance.

Starting November 15, 2025, the Punjab Environmental Protection Agency (EPA) will ban vehicles without a valid Green Emission Sticker from public roads.

.This rule isn’t just a government formality; it’s a move toward cleaner cars, safer air, and a healthier Pakistan.

In this blog, we will walk you through:

What is a Green Emission Sticker and who needs it?

  1. What it is
  2. Who’s required to get it (older than 3 years)
  3. What authority issues it (Punjab EPA)
  4. How and Where to get your Vehicle Tested

The Green Emission Sticker is the official compliance badge issued by the Punjab EPA (Environmental Protection Agency). This diagnostic procedure determines the amount and type of pollutant your vehicle emits. Moreover, the EPA has taken this initiative to tackle the smog and pollution caused by vehicle emissions. 

Who’s required to get it?

According to credible sources, vehicles older than three years must pass this test. The new cars are temporarily exempted, but rules are evolving. 

How and where to get your vehicle tested?

The Emission test is performed with the help of mobile testing units (vans equipped with emission-testing machines i, i.e., an exhaust gas analyzer or other devices for checking vehicles on the spot). In addition, you can have your cars tested at fixed emission-testing stations throughout the city. 

You can download the “Green Punjab App” if you need any help or want to report a vehicle emitting excessive smoke. It also provides features like air quality tracking, traffic alerts, and updates on complaint status. 

Apart from this, you can also call the 1373 helpline for any queries or reports related to vehicle emission control, testing procedures, or pollution complaints.

What does the green vehicle test check?

The Green Vehicle test determines the amount of the following components;

As the concentration of these gases increases, they harm the environment, pollute the air, and affect human respiratory health.

If the car passes specific quality standards, then you’ll get a certificate and a sticker “with QR code” as shown in the image below.

Why is emission test important for your car?

The Green Emission test is essential for cars, as it is a major contributor to a clean, pollution-free environment, improves engine life, and ensures the vehicle’s legal compliance with environmental safety standards. 

Failing the test usually reveals neglected maintenance, such as clogged air filters, worn-out oxygen sensors, and dirty or failing catalytic converters. 

For your convenience, we have provided an inspection checklist for your review. Curious to know? If yes, keep reading this informational guide! 

Maintenance tips for passing the emission test

You need to follow these maintenance guidelines to ensure that you will clear the test. 

Dirty or clogged air filters can restrict airflow into the engine, leading to incomplete combustion and increasing the risk of harmful emissions. It is important to check air filters every 12,000-15,000 miles (19,000-24,000 km).

 Always check your car’s owner manual for specific recommendations.

    The second step is to check the color of exhaust smoke. If you see thick white, black, or blue smoke, then you should seek a proper diagnosis of your vehicle. 

   Key Insight: Don’t ignore that smoke! Book a PakWheels Car Inspection today and let experts find out what’s wrong before your emission test does.

     The O₂ (oxygen) and MAF (mass air flow) sensors help your engine burn fuel efficiently.  The O2 sensor is located in the exhaust system, and the MAF is near the air intake. Both adjust the air-fuel mixture, and if they fail to do so, it can lead to higher fuel consumption, increased emissions, and a risk of failing emission tests.

       You should keep your catalytic converter intact, as it helps turn harmful gases into less toxic ones. If it’s damaged or removed, your car emits more pollution and may fail the emission test.

Doing this ensures your car meets vehicle emission testing standards and helps you earn your Green Emission Sticker on the first try.

Step Action Why It Matters
1 Confirm if your vehicle is older than 3 years Older vehicles must be tested under the emission inventory Punjab regulations
2 Visit an authorized ETS center Only EPA-approved centers issue the sticker
3 Inspect your car first Fix smoke, filters, or sensors before testing
4 Take the emission test Tests CO, HC, NOx, and opacity
5 Pass = Get your sticker Receive certificate and display visibly
6 Fail = Fix & retest Repair issues and return for testing
