In which year was China 5 implemented?

China 5, the fifth-stage national motor vehicle emission standard, was implemented nationwide from January 1, 2017. The emission control level of the China 5 standard is equivalent to the fifth-stage emission standard implemented in Europe. The European Union has been enforcing it since 2009, with stricter limits on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles compared to the China 4 standard. More details are as follows: 1. From China I to China IV, each upgrade in the standard reduces single-vehicle pollution by 30% to 50%. Additionally, starting from April 1, 2016, all imported, sold, and registered light gasoline, light diesel passenger vehicles, and heavy-duty diesel vehicles (only for public transportation, sanitation, and postal purposes) in the Beijing-Tianjin-Hebei region must comply with the China 5 emission standard. 2. The motor vehicle pollutant emission standards are formulated to implement environmental protection laws, reduce and prevent pollution from vehicle exhaust, protect the ecological environment, and ensure human health. 3. Compared to the China 4 standard, the China 5 standard reduces harmful gas emissions such as nitrogen oxides by 43% for heavy-duty vehicles and by 25% for new standard light-duty vehicles, significantly improving the environment and benefiting everyone's health.
I remember the nationwide implementation of China's National V emission standards was in 2017, specifically starting from January 1st, 2017, for light-duty gasoline vehicles. Actually, Beijing took action much earlier, implementing the equivalent Beijing V standard as early as 2013, while places like Shanghai and Jiangsu also adopted it ahead of schedule in 2016. The SUV I bought at that time was among the first batch of National V compliant vehicles, with more accurate fuel consumption display compared to older models. National V mainly regulates the emission levels of nitrogen oxides and particulate matter in exhaust gases, with much stricter testing requirements than National IV, prompting many automakers to upgrade their technologies in advance. Most vehicles on the road today still comply with National V standards, but with the introduction of National VI in recent years, new vehicles have basically switched to the new standard.
When it comes to the implementation of China V emission standards, what impressed me the most was that Beijing started enforcing it as early as February 2013, which was called Beijing V standards at the time—essentially an early version of China V. First-tier cities like Guangzhou and Shenzhen also acted swiftly, implementing China V standards for light-duty vehicles in 2015. The nationwide unified implementation didn't occur until January 2017, and my neighbor happened to buy a sedan that was among the first batch compliant with the new standards. The China V standards for heavy-duty diesel vehicles were delayed until July 2017, mainly targeting large trucks and similar vehicles. After that upgrade, many gas stations also switched to higher-quality fuel, and the queues at vehicle emission testing stations became shorter. It genuinely contributed to improved air quality.
