Overview

In the heart of South Asia, where economic growth and industrial expansion fuel rapid urbanization, an invisible crisis threatens public health—air pollution. Bangladesh, despite its economic progress, experiences some of the highest levels of air pollution globally. The average citizen's lifespan is reduced by 6.9 years due to poor air quality, with particulate matter (PM2.5) concentrations nearly 15 times the WHO guideline.

Among the primary contributors to this crisis are brick kilns, which account for 58% of Dhaka's fine particle pollution. Although regulations were introduced in 2014 to restrict kiln operations near residential areas, schools, and healthcare facilities, enforcement remains a challenge. The Department of Environment (DoE) reports that 60% of Bangladesh's 7,881 kilns operate without environmental clearance, significantly impacting air quality and public health.

To strengthen enforcement, the ARCED Foundation, in collaboration with the National University of Singapore and the University of Nottingham, has developed the Brick Kiln Tracker—a digital tool that leverages satellite imagery and machine learning to identify, locate, and assess the environmental impact of brick kilns. The tracker enables authorities to prioritize enforcement based on the kilns' proximity to population centers, schools, and healthcare facilities, ensuring that efforts are directed where they will have the greatest impact.

A Data-Driven Approach to Environmental Enforcement

Addressing a challenge as complex as air pollution requires more than just policy mandates—it demands precise, data-driven interventions that can guide enforcement where it is most needed. The Brick Kiln Tracker is designed to bridge this gap, equipping regulatory authorities with real-time insights to enhance enforcement efficiency and reduce public health risks.

At its core, the initiative follows a structured theory of change, ensuring that technology translates into tangible environmental and health benefits:

• From Data to Action: Providing regulators with a clear, real-time view of brick kiln locations and their environmental impact enables targeted enforcement rather than broad, resource-intensive inspections. The goal is to ensure that the most harmful kilns—those posing the greatest health risks—are prioritized.
• Shaping Industry Behavior: As enforcement becomes more strategic, kiln owners face a clear choice: comply with environmental standards, upgrade to cleaner technologies, or cease operations. This shift encourages the adoption of gas and electric kilns and promotes alternative low-emission building materials, reducing long-term reliance on traditional brick kilns.
• Improving Public Health Outcomes: As regulatory oversight strengthens and compliance increases, air quality improves, directly reducing exposure to harmful pollutants. This, in turn, lowers the incidence of respiratory diseases, cardiovascular conditions, and other pollution-related health issues.
• Ensuring Sustainability: To embed these improvements into Bangladesh's environmental governance, the project aims to transfer the technology to the DoE upon successful implementation. Government officials will receive comprehensive training to update and maintain the system, ensuring that data-driven enforcement remains an integral part of regulatory frameworks.

Implementation and Progress

Since its launch, the Brick Kiln Tracker Initiative has made significant strides in strengthening environmental enforcement and promoting cleaner alternatives.

• Mapped and assessed 7,881 brick kilns across Bangladesh using satellite imagery and machine learning, providing authorities with an unprecedented level of visibility into kiln operations.
• Trained district-level officials from all DoE offices on how to effectively use the tracker, enhancing their capacity to target enforcement actions toward high-impact polluters.
• Engaged with policymakers, including multiple high-level meetings with the Ministry of Environment, Forestry, and Climate Change, ensuring institutional buy-in and long-term policy integration.
• Conducted baseline and midline surveys with 100-plus DoE officials and 600 kiln owners, capturing critical insights into enforcement challenges and industry responses to regulatory measures.
• Launched the tracker in February 2023 at a workshop hosted by the DoE, marking a milestone in digitizing environmental governance.
• Initiated a large-scale randomized controlled trial (RCT) to rigorously evaluate the impact of the tracker on enforcement effectiveness, pollution reduction, and technology adoption in the sector.
• Explored alternative solutions to traditional brick kilns, such as gas and electric kilns and concrete blocks, to promote sustainable construction materials and reduce reliance on high-emission technologies.

With enforcement authorities actively using the tracker and the ongoing evaluation providing real-time insights, the project is well-positioned to drive meaningful policy changes and improve air quality across Bangladesh.

Looking Ahead

The project has the potential to significantly improve air quality and public health in Bangladesh. If successful, it will serve as a model for enhancing environmental enforcement through technology, with applications beyond brick kilns to other forms of industrial pollution. The ultimate goal is to integrate data-driven governance into long-term regulatory frameworks, ensuring that environmental standards are effectively upheld.

By leveraging technology, policy, and enforcement, this initiative represents a strategic step toward sustainable air quality management in Bangladesh.
