What National Emission Standard Should a Car Produced in 2014 Comply With?

[JulietLee]

Cars produced in 2014 could comply with either National IV or National V emission standards. You can check the environmental label located at the upper right corner of the vehicle's windshield, which indicates the specific emission standard the car meets. The primary pollutants emitted by automobiles include carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM). These pollutants originate from the exhaust pipe, crankcase, and fuel system. The National IV emission standard represents the fourth phase of China's motor vehicle pollutant emission regulations, targeting key pollutants such as HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). This standard achieves reduced emission levels through advanced technologies like improved catalytic converter active layers, secondary air injection systems, and cooled exhaust gas recirculation systems, effectively controlling and minimizing vehicle emissions below specified thresholds.

I remember when I bought that car in 2014, the salesperson said the mainstream standard was China IV, but some new models had already upgraded to China V. This was because emission standards were transitioning that year, with stricter environmental policies requiring better pollutant control, such as slightly lower nitrogen oxide levels. China IV cars were still fine for daily driving, but if you're buying a used car now, you'd better confirm the standard, as some big cities like Beijing might have unfriendly restrictions for China IV vehicles. Generally, cars from 2014 were either China IV or China V, and you can check the vehicle registration information at the DMV to find out.

As a car enthusiast, I've studied the evolution of China's emission standards. 2014 was the transition period from China IV to China V. Early-year vehicles were mostly China IV compliant, while later batches produced China V compliant cars. The main difference lies in exhaust purification requirements, with China V having stricter particulate matter control. Policy-wise, China introduced the China V standard by late 2013, but implementation varied by region—coastal cities in southern China might have adopted it earlier. You can confirm the standard by checking the vehicle's nameplate or environmental label, which affects both environmental performance and used car resale value.

Last month I wanted to buy a used 2014 car, so I first checked the emission standards. Many 2014 cars meet China IV standards, but some high-end or newer models are China V compliant. When purchasing, check the environmental compliance list as the standard affects annual inspections and urban driving restrictions. For example, China IV vehicles are banned from city centers in some areas. I recommend directly asking the owner or checking 4S store records for a quick and easy solution.

From an environmental perspective, most vehicles in 2014 adopted China IV or China V emission standards. The China V standard began its promotion in that year, aiming to reduce tailpipe pollutants such as hydrocarbons and nitrogen oxides, thereby helping to improve air quality. Driven by policy, automakers gradually transitioned at the beginning of the year. Opting for China V-compliant vehicles better supports green mobility, as emission standards directly impact planetary health—making this a priority when purchasing a car.

I've been driving my 2014 model car for almost ten years now, which was manufactured to meet China IV emission standards. It runs fine for daily use, though the standard affects some minor details. For instance, the fuel consumption is slightly higher than China V compliant vehicles, and exhaust emission tests during maintenance might take a bit more time. Emission upgrades are beneficial—China V is more environmentally friendly—but China IV is sufficient for daily commuting and doesn't compromise safety.
