Bangladesh is one of the fastest growing economies in South Asia. Caused by decades of rapid economic growth, Bangladesh grapples with a severe waste and pollution problem. The entire country, but in particular its capital, are subject to fast unplanned urbanization and population growth. Today, with almost 24 million people, Dhaka represents one of the biggest metropolitan areas worldwide. Given the pace of development, the local infrastructure, traditional methods for production and
construction and waste management, in combination with insufficient policies are not fit-for-purpose. Almost the entire population of Bangladesh lives in bad air, with the central part of the country, including Dhaka, being the most polluted. Given its population density, Dhaka faces the culmination of the national problems like a magnifying glass and as a result, it has become one of the most polluted cities worldwide.
Following a description of the issue of air pollution in Dhaka, part 1 of this essay examines the main environmental and social consequences, as well as the effectiveness of current policy implementation, in light of the Environmental Kuznets Curve (EKC) hypothesis. This section of the essay also sheds some light on the key stakeholders in relation to the severe air pollution issue. Part 2 presents a range interventions to address the problem from various angles in order to achieve a sustainable improvement of air quality. The conclusion at the end synthesizes previous thoughts and provides suggestions for further research on the matter.
An indicative questionnaire is furthermore presented in Appendix III, with the objective to guide qualitative interviews with users of the Dhaka transportation system. The gathered information is deemed useful for decision-makers who aim at greening Dhaka’s transportation sector.

Zusammenfassung der Kapitel (Chapter Summaries)
1. Introduction: This introductory chapter sets the stage by highlighting Bangladesh's rapid economic growth and the resulting severe waste and pollution problem, particularly in Dhaka. It emphasizes the city's rapid unplanned urbanization and population growth, leading to inadequate infrastructure and insufficient policies for waste and pollution management. The chapter outlines the essay's structure, focusing on the environmental and social consequences of air pollution, policy effectiveness, potential interventions, and concluding remarks. The inclusion of an appendix with a questionnaire for qualitative interviews is also mentioned.
2. Air pollution in Dhaka and why it matters: This chapter details the alarmingly poor air quality in Dhaka, consistently ranking among the worst globally. It presents data illustrating the significant increase in fine particulate matter (PM2.5) concentration over three decades, a regression of SDG indicator 11.6.2. The chapter uses figures to visually represent the poor air quality index over the period of 2016-2020, showcasing the limited time Dhaka experienced good air quality. Root causes are identified, including rapid urbanization, industrialization, traffic congestion, inadequate regulations, and weather patterns, with specific examples like brick kilns, traffic, and fossil fuel dependency. The chapter further highlights the interconnectedness of air pollution across South Asia, demonstrating that Dhaka's pollution is not solely a local issue.
3. The Environmental Kuznets Curve (EKC) and air pollution in Dhaka: This section explores the Environmental Kuznets Curve (EKC) hypothesis, which suggests that air pollution initially increases with economic development before decreasing at higher levels. Bangladesh's situation, where strong economic growth coincides with worsening air quality, suggests the country is on the ascending side of the EKC. This implies that significant improvements in air quality may require considerably higher levels of economic development.
4. The urgency for effective action: This chapter stresses the urgent need for action to mitigate the devastating effects of air pollution in Dhaka. It highlights the projected increase in urban populations in less developed countries by 2050, positioning Dhaka as a representative case study for many developing megacities. The disproportionate burden of air pollution on low- and middle-income countries is emphasized, emphasizing that solutions for Dhaka could serve as a global blueprint, with the potential for economies of scale to facilitate innovative interventions.
Part 1 - Main social and environmental consequences of air pollution in Dhaka and effectiveness of policy implementation: This part details the environmental and social impacts of air pollution in Dhaka, acknowledging that the municipal-level impacts likely mirror, and potentially exacerbate, national-level effects. The *Environmental consequences* section discusses the effects on plants, trees, and ecosystems, impacting food production and ecological balance. The *Social consequences* section focuses on public health, emphasizing premature deaths attributed to air pollution and the loss of life expectancy for Dhaka residents, relating these effects to relevant SDG indicators.
