New Research Brief: Ending Childhood Lead Poisoning Through Business Action – Insights from Bangladesh

This research brief, developed by The Centre for Child Rights and Business in partnership with UNICEF, explores childhood lead poisoning through a private-sector lens. It examines how business activities, supply chains and market incentives contribute to lead exposure risks in Bangladesh, while highlighting the critical role companies can play in preventing harm and protecting children's rights.

Drawing on desk research, expert interviews and supply chain analysis, the brief focuses on two sectors where lead-related risks are particularly significant: lead-acid batteries and lead-containing pigments used in manufacturing. It explores how lead moves through supply chains, where exposure risks emerge, and the governance, traceability and market challenges that can make those risks difficult to address.

Childhood lead poisoning is one of the most widespread and preventable environmental health threats globally. In Bangladesh, an estimated 20 million children are affected by elevated blood lead levels, with consequences for health, learning, development and future economic opportunities. Lead exposure remains deeply embedded in the way some products are manufactured, traded and recycled, making business engagement essential to achieving sustainable solutions.

The brief highlights opportunities for businesses to strengthen human rights due diligence, improve supply chain transparency and adopt safer practices that reduce exposure risks for children, workers and communities. It also outlines practical recommendations for governments, businesses, investors and international buyers to accelerate progress toward ending childhood lead poisoning.
