Vehicles are one of major source of air pollution, contributing to smog, respiratory problems, and other health issues. To address this concern, the European Union established the Euro standards, a series of regulations that set progressively stricter limits on the amount of pollutants allowed in the exhaust gases of new vehicles. This article will explore the Euro standards in detail, including what they regulate and how they are being implemented in countries like Indonesia.
The Euro standards were first introduced in 1992, with Euro 1, and have since evolved through several iterations, each with progressively stricter limits on emissions. The Euro 2 introduced in 1996, then Euro 3, 4 and 5 were introduced in 2000, 2005 and 2009 respectively. As of now, the latest standard is Euro 6, which was implemented in 2014 for passenger cars and light commercial vehicles, and later extended to heavy-duty vehicles.
What is Regulated in the Euro Standard
The Euro standards regulate several key pollutants emitted by internal combustion engines. The main pollutants targeted by these standards include:
- Nitrogen Oxides (NOx): NOx emissions are a major contributor to air pollution and have significant health impacts, including respiratory problems and the formation of ground-level ozone.
- Carbon Monoxide (CO): CO is a colorless, odorless gas that can be harmful when inhaled in large amounts. It can cause dizziness, confusion, and even death at high concentrations.
- Hydrocarbons (HC): Unburned hydrocarbons contribute to the formation of ground-level ozone and smog, which can have severe health and environmental consequences.
- Particulate Matter (PM): PM consists of tiny particles that can penetrate deep into the lungs and even enter the bloodstream, causing a range of health issues from respiratory problems to cardiovascular diseases.
The Euro standards specify maximum allowable amounts of these pollutants, measured in grams per kilometer (g/km) for vehicles and grams per kilowatt-hour (g/kWh) for ships. Each new Euro standard progressively tightens these limits, pushing manufacturers to develop cleaner technologies.
The Euro standards have progressively tightened the allowable limits for these pollutants. For example:
- Euro 1 focused on reducing CO and HC emissions.
- Euro 2 introduced limits for NOx and added PM limits for diesel vehicles.
- Euro 3 and Euro 4 further reduced CO, HC, and NOx limits and added stricter PM limits.
- Euro 5 introduced more stringent limits for NOx and PM, especially for diesel vehicles, and began regulating direct-injection petrol engines.
- Euro 6 imposed the strictest limits to date, particularly on NOx and PM emissions from diesel vehicles, and introduced particle number (PN) limits to address ultrafine particles.

Implementation of Euro in Indonesia
Indonesia, like many other countries, faces significant challenges with air pollution, particularly in its urban areas. As a response, the Indonesian government has taken steps to adopt and implement Euro standards to improve air quality and public health.
The implementation of Euro standards in Indonesia began with the adoption of Euro 2 standards for new vehicles in 2007. This marked a significant step forward in regulating vehicle emissions in the country. In 2018, Indonesia announced the adoption of Euro 4 standards, which came into effect for all new vehicles in 2021. This move was aimed at significantly reducing NOx, CO, HC, and PM emissions from vehicles, aligning the country’s emission regulations more closely with international standards.
The Euro standards represent a critical framework for controlling vehicle emissions and improving air quality. By setting stringent limits on harmful pollutants, these standards help protect public health and the environment. Indonesia’s efforts to adopt and implement Euro standards, from Euro 2 to Euro 4, demonstrate a commitment to reducing air pollution and enhancing the quality of life for its citizens. Continued progress and stricter enforcement of these standards will be essential for achieving long-term environmental and health benefits.
