Jakarta Ranks Fourth-Worst in the World for Air Quality
Jakarta’s Morning Air Quality Reaches Unhealthy Level
Kabarsaji.com – Jakarta began Friday under unhealthy air conditions, placing the Indonesian capital fourth on the global list of cities with the poorest air quality at the time of measurement. The reading highlighted continuing concerns over fine-particle pollution as the city approaches its annual dry-season period.
At 05:55 local time, Jakarta recorded an Air Quality Index, or AQI, of 169. The figure was classified as unhealthy, with PM2.5 concentrations measured at 87 micrograms per cubic meter. PM2.5 refers to extremely small airborne particles that can remain suspended in the air and are a key indicator used in air-quality assessments.
The unhealthy classification signals conditions that may affect people and sensitive animal populations, while also posing risks to vegetation and reducing environmental quality. Residents, particularly those more vulnerable to polluted air, are encouraged to reduce time spent outdoors where possible.
Advice for Residents During Poor Air Conditions
People who need to be outside are advised to wear a mask and limit unnecessary outdoor activity. Keeping doors and windows closed can also help reduce the amount of polluted outdoor air entering homes and workplaces.
Air-quality readings can change during the day, so residents may find it useful to monitor local conditions before planning outdoor exercise, travel, or other extended activities outside. The AQI is intended to give the public a simple indication of the potential health implications of current pollution levels.
A “Good” air-quality category represents conditions that do not create health risks for people or animals and do not harm plants, buildings, or visual environmental quality. In the supplied scale, this category corresponds to PM2.5 values from 0 to 50.
The next level, “Moderate,” covers readings from 51 to 100. At that stage, air quality is not expected to affect human or animal health, though sensitive vegetation and aesthetic conditions may be affected.
More severe classifications bring greater concern. A “Very Unhealthy” reading falls within the 200 to 299 range and can harm groups exposed to the pollution. The “Hazardous” category, ranging from 300 to 500, indicates air conditions that can cause serious health problems across the population.
Other Cities on the Global Pollution List
Lahore in Pakistan held the worst air-quality position with a score of 208. Manama, Bahrain, followed with 181, while Kolkata, India, registered 178. Delhi, India, recorded 159, placing it below Jakarta’s 169 reading in the ranking at that time.
Such comparisons offer a snapshot rather than a permanent order. Air quality can vary because of weather conditions, seasonal patterns, emissions, and the movement of airborne particles. Still, Jakarta’s position near the top of the list underscores the scale of the challenge facing one of Southeast Asia’s largest urban areas.
Dry-Season Response Plans
The Jakarta Provincial Government is preparing a rapid response to address air pollution during the dry season, which is forecast to run from early May through August. The planned measures include improvements to air-quality monitoring and motor vehicle emissions testing.
Strengthening monitoring systems can help authorities identify pollution conditions more quickly and provide clearer information to the public. Emissions tests for vehicles are also part of the immediate response being prepared for the seasonal period, when air-pollution concerns can become more prominent.
Officials are also reviewing Jakarta’s Air Pollution Control Strategy, known as SPPU. The evaluation covers several areas, including trends in PM2.5 pollution, emissions produced by different sectors, and the consequences of poor air quality for public health.
The focus on PM2.5 is significant because these particles are small enough to be a central measure in assessing whether air is safe, moderate, unhealthy, or more dangerous. Tracking their movement over time can help show whether pollution-control efforts are producing improvements and where further action may be needed.
Need for Regional Cooperation
Jakarta’s provincial administration has stressed that air pollution cannot be resolved through isolated action by a single jurisdiction. The issue requires coordinated work among government agencies and cooperation across the wider region, including surrounding areas.
This approach reflects the fact that air does not remain within administrative boundaries. Pollution affecting residents in Jakarta may be influenced by activities across a broader area, making joint planning and consistent action important to long-term control efforts.
For residents, Friday’s unhealthy reading serves as a reminder that air quality is not simply an environmental measurement. It can shape everyday decisions, from whether to exercise outdoors to whether additional precautions are needed when travelling or spending time outside. As Jakarta prepares for the dry season, public information, monitoring, emissions controls, and regional coordination will remain central to efforts to reduce pollution exposure.
