Bangladesh kilns cut pollution by 30% but workers earn no more

Bangladesh’s brick industry has cut pollution, but the benefits haven’t reached the workers who produce the bricks, a new study finds. Researchers measured emissions from traditional kilns and from kilns that use simple, cleaner technologies such as pre‑heating fuel and improved combustion. The cleaner kilns released up to 30 % less carbon dioxide and used 40 % less fuel. Bricks produced were stronger and more uniform, which could lower costs for builders. Yet the study shows that the cost savings went to kiln owners, not to the laborers who load and fire the bricks.

The country’s brick sector is a major source of air pollution, especially in rural districts. Kilns burn wood or coal in poorly ventilated spaces, spewing fine dust and toxic gases that hurt local communities. In recent years the government, NGOs and private investors have promoted cleaner kiln designs to meet growing environmental standards and to reduce health risks. The new research builds on earlier pilot projects that introduced pre‑heating and better airflow, but it also highlights that the economic gains from lower fuel costs and higher quality bricks have not translated into higher wages or safer working conditions for the 1.5 million people employed in the sector.

Data from the study show that while emissions fell and brick quality improved, workers’ wages stayed flat and most still worked in dusty, poorly lit environments. The owners of the kilns reported that the lower fuel bill allowed them to lower the selling price of bricks, boosting sales. The workers, who are mostly women and teenagers, saw no increase in pay or benefits. The study points out that without a regulatory framework to redistribute savings, environmental progress can leave the most vulnerable workers behind. It also notes that the health risks from dust exposure remain high, with many workers suffering chronic respiratory problems.

Researchers call for new policies that link environmental upgrades to worker welfare. They suggest subsidies for small kiln owners to share savings with laborers, mandatory training on safety, and wage floors tied to productivity gains. The government has begun reviewing labor standards for the brick industry, but enforcement remains weak. If the sector can align environmental and social goals, Bangladesh could set a model for other developing economies. The next step will be to monitor how policy changes affect both emissions and workers’ livelihoods.
