Brick kilns in Bangladesh produce damaging air pollution, accounting for 30-50 percent of particulate matter (PM2.5) emissions, which can cause cardiovascular and respiratory disease and even death. The Bangladesh government has attempted to regulate these kilns, but weak enforcement and underreporting have allowed the kilns to continue to operate. Using satellite remote sensing, this project will collect objective information on the number, type, and location of brick kilns in use across Bangladesh. The data will be disseminated through a publicly available website and used to catalyze a discussion among stakeholders in the public, private, and community sectors to work towards a system of brick manufacturing that is less harmful to human health and the environment.
