Jakarta's Pollution Crisis: A Dire Situation

Jakarta, Indonesia's bustling capital, is known for its vibrant culture and economic opportunities. However, it has been dubbed the most polluted city in the world by Swiss air quality technology company IQAir. Jakarta's air quality has fluctuated between good and OK since 2018, but there has been a recent increase in pollution. This is due to a combination of factors, including vehicular emissions, industrial pollutants, and the burning of forests. The health impacts of air pollution in Jakarta are severe, with an estimated 2,000 deaths per year caused by heart attacks, strokes, lung cancer, and other health conditions linked to air pollution. The economic costs of air pollution in the city amount to $1.1 billion annually.

Jakarta is the world's most polluted city

Jakarta, Indonesia's bustling capital, has been dubbed the world's most polluted city. More than 10 million residents of Jakarta have to breathe polluted toxic air every day. The air pollution in the city has been so severe that even President Joko Widodo has been affected by the problem.

There are several factors contributing to Jakarta's poor air quality. Firstly, the dry season and motorized vehicles are the main causes of air pollution in the city. The lack of rainfall and higher temperatures during the dry season lead to a buildup of harmful particulate matter, such as PM2.5, PM10, and Black Carbon, which are associated with vehicle emissions, coal combustion, and industrial processes. Vehicular emissions, particularly from the ever-increasing number of cars and motorbikes in the city, release high levels of carbon monoxide and other toxic gases into the atmosphere, making outdoor activities like jogging or cycling challenging in built-up areas.

Secondly, Jakarta is surrounded by coal power plants and industrial zones that emit pollutants such as sulfur dioxide and other toxins. Inadequate emissions controls and monitoring have allowed these industrial pollutants to accumulate, further deteriorating air quality. Construction activities and rapid urban development also generate dust and pollutants, with unregulated construction practices often lacking proper dust control measures. The concreting over green spaces and woodlands has reduced the city's natural capacity to absorb pollutants.

The health impacts of Jakarta's air pollution are significant. A 2022 report by the Air Quality Life Index (AQLI) found that air pollution reduces the life expectancy of Jakarta citizens by three to four years. Additionally, an analysis by CREA estimated that air pollution causes nearly 2,000 deaths per year in Jakarta, primarily due to heart attacks, strokes, lung cancer, and chronic respiratory diseases. The economic costs of air pollution in Jakarta are also substantial, amounting to approximately USD 2,943.42 million annually.

While the Widodo administration is building a new national capital on the island of Borneo to alleviate some of these issues, Jakarta's air pollution crisis remains a pressing concern for its residents and a challenge for the government to address.

Air pollution reduces life expectancy by 1.5-4 years

Jakarta, Indonesia's capital, has recently been named the world's most polluted city. More than 10 million residents of Jakarta have suffered from some of the worst air pollution recorded anywhere in the world. Vehicular emissions are a primary contributor to Jakarta's air pollution, with high levels of carbon monoxide and other toxic gases being released into the atmosphere. The city's surrounding industrial zones also emit pollutants such as sulfur dioxide, and the burning of coal, the most polluting of fossil fuels, has further deteriorated air quality. Construction activities, deforestation, and the concreting of green spaces have also contributed to the problem.

The impact of air pollution on the health of Jakarta's residents is significant. A 2022 report by the Air Quality Life Index (AQLI) found that air pollution slashes three to four years off Jakarta citizens' life expectancy. This is due to the increased risk of heart attack, stroke, lung cancer, chronic respiratory disease, and other health conditions linked to air pollution. Another study, using data from 2018 and 2019, found that air pollution was responsible for over 10,000 deaths in Jakarta each year.

On a global scale, air pollution is estimated to reduce average life expectancy by around 1.8 years, with the impact being greater in less-developed areas. Regions with high levels of ambient PM2.5, such as the Middle East, North Africa, and South, Central, and East Asia, tend to have the largest losses in life expectancy due to air pollution. For example, in Egypt, air pollution results in a loss of 2.11 years of life expectancy, while in India, the loss is estimated to be 1.51 years.

The effects of air pollution on life expectancy are complex and influenced by various factors, including individual characteristics such as age, sex, and underlying health status. Countries with older populations tend to be more heavily impacted by air pollution, as diseases worsened by air pollution occur mainly in older individuals. Additionally, the impact of air pollution on life expectancy can be influenced by socioeconomic factors, with higher-resourced countries experiencing a greater impact from PM2.5 and lower-resourced countries being more affected by household air pollution.

Addressing air pollution in Jakarta is crucial to improving the health and well-being of its residents. While the Indonesian government has proposed building a new capital in Borneo to alleviate the problem, it is essential to implement measures to reduce emissions, promote sustainable transportation, and regulate construction practices to mitigate the impact of air pollution on the city's residents.

Motor vehicles are a major cause

Jakarta, Indonesia's bustling capital, has been dubbed the “most polluted" city in the world, with air quality plunging to alarming levels. The city's more than 10 million residents have to cope with the harmful effects of toxic air pollution on a daily basis. One of the primary contributors to Jakarta's poor air quality is vehicular emissions from the growing number of motor vehicles on the roads.

The Indonesian government has implemented measures to address this issue, such as the odd-even policy, which restricts vehicles based on number plates. Additionally, gasoline vehicles produced after 2007 must meet certain emission standards, with CO2 levels below 1.5% and hydrocarbon levels below 200 parts per million. Despite these efforts, the impact of motor vehicles on Jakarta's air quality remains a significant concern.

To further mitigate the impact of motor vehicles on air pollution, Jakarta has introduced Low Emission Zones (LEZs), where motorized vehicles are restricted, and only pedestrians, cyclists, public transport, and low-emission vehicles are allowed. The city has also focused on promoting sustainable transportation and improving public transport options, such as the MRT, to encourage residents to leave their cars at home.

While motor vehicles play a significant role in Jakarta's air pollution, it is important to recognize that there are other contributing factors as well. These include emissions from surrounding industrial zones, coal-fired power plants, and the burning of forests and peatlands. However, addressing the issue of motor vehicle emissions remains a crucial aspect of the city's overall strategy to improve air quality and protect the health of its citizens.

The dry season worsens air quality

Jakarta, Indonesia's bustling capital, is known for its vibrant culture and economic opportunities. However, smog and air pollution have become an increasingly prominent issue. In 2023, Jakarta was named the 'most polluted' city in the world, with air quality plunging to some of the worst levels ever recorded.

The dry season significantly worsens air quality in Jakarta. Indonesian authorities have identified the dry season and motorized vehicles as the primary causes of the city's air pollution. The combination of these factors leads to a haze blanketing the city's main business district. Exhaust emissions from the growing number of cars, motorbikes, and scooters on the roads contribute to high levels of carbon monoxide and other toxic gases in the atmosphere. This makes outdoor activities like jogging, cycling, or walking challenging in Jakarta's built-up areas.

The dry season also exacerbates the impact of other sources of pollution in Jakarta. The city is surrounded by coal power plants, and inadequate emissions controls have allowed industrial pollutants to accumulate, further deteriorating air quality. Construction activities and unregulated urban development generate dust and pollutants, with limited controls in place to mitigate dust pollution. The concreting over of green spaces and woodlands has reduced the area's natural capacity to absorb pollutants.

Additionally, the burning of forests in Indonesia has contributed to the haze over Jakarta during the dry season. Deforestation in the rainforests of Kalimantan and Sumatra, often referred to as the lungs of Indonesia, is occurring at alarming rates. This loss of vegetation worsens the effects of climate change, leading to hotter and drier conditions that can further impact air quality.

The air pollution in Jakarta has severe health and economic consequences. According to a 2022 report by the Air Quality Life Index (AQLI), air pollution reduces the life expectancy of Jakarta citizens by three to four years. It is estimated to cause nearly 2,000 deaths per year and USD 1.1 billion in economic costs. These deaths are attributed to heart attacks, strokes, lung cancer, chronic respiratory diseases, and other health conditions linked to air pollution.

Industrial emissions are a key factor

Jakarta, Indonesia's bustling capital, has consistently ranked among the most polluted cities globally. The city's more than 10 million residents have to deal with the harmful effects of toxic air pollution on a daily basis. Industrial emissions are a key factor in this.

The industrial zones surrounding Jakarta emit pollutants such as sulfur dioxide and other toxins. Inadequate emissions controls and monitoring have allowed these industrial pollutants to accumulate, severely degrading the city's air quality. Jakarta's rapid urban expansion has also led to the concreting of green spaces and woodlands, reducing the natural capacity of the area to absorb pollutants. The city's expansion has been accompanied by a rise in motor vehicles, leading to increased vehicular emissions and traffic congestion. This has resulted in high levels of carbon monoxide and other toxic gases in the atmosphere, making outdoor activities like jogging or cycling difficult in the more built-up areas.

The burning of Indonesia's forests has also contributed to the haze over Jakarta. Additionally, the city's power supply still relies on coal, the most polluting of fossil fuels. The combination of industrial emissions, vehicular emissions, and forest burning has resulted in dangerously high levels of pollution, particularly during the dry season when a lack of moisture in the atmosphere allows pollutants to accumulate.

The health impacts of Jakarta's air pollution are severe. A 2022 report by the Air Quality Life Index (AQLI) found that air pollution reduces the life expectancy of Jakarta's citizens by three to four years. An analysis by CREA estimated that air pollution causes nearly 2,000 deaths per year in Jakarta, primarily due to heart attacks, strokes, lung cancer, and chronic respiratory diseases. Other health impacts include new cases of asthma and preterm births.

To address the issue of industrial emissions, Jakarta needs to implement stricter emissions controls and monitoring. This could include the implementation of carbon taxes on high-emitting industries. Additionally, the city should focus on promoting sustainable transportation and expanding its public transportation systems to reduce the number of vehicles on the road. By addressing these issues, Jakarta can work towards improving its air quality and reducing the health risks associated with industrial emissions.
