Boston University Scholar Examines International Frameworks for Global Chemical Governance

Amajor new policy brief authored by Professor Henrik Selin of Boston University's Frederick S. Pardee School of Global Studies provides an in-depth analysis of the evolving international framework governing hazardous chemicals, toxic waste, and global pollution. As international leaders, environmental scientists, and diplomats prepare for pivotal global negotiations under the auspices of the United Nations Environment Programme, Selin's research highlights critical gaps in current multilateral agreements while offering actionable pathways for effective governance.

Chemical contamination and pollution represent one of the three planetary crises identified by international authorities, alongside climate change and biodiversity loss. Despite the expansion of global trade in synthetic chemicals and industrial materials over recent decades, the regulatory mechanisms designed to mitigate risks remain fragmented across various isolated treaties. Selin's policy brief underscores the urgent necessity for a cohesive, modernized global framework capable of managing the life-cycle impacts of hazardous substances from production to waste disposal.

Key Treaties and Governance Frameworks Analyzed: The policy brief provides a thorough assessment of existing multilateral environmental agreements, including:

• The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal.
• The Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade.
• The Stockholm Convention on Persistent Organic Pollutants.
• The Minamata Convention on Mercury.

Selin highlights that while these individual conventions have achieved notable progress in banning or restricting specific toxic compounds like mercury and polychlorinated biphenyls, they often struggle to keep pace with the massive volume of new chemical compounds introduced to market every year. Furthermore, modern challenges such as microplastics, per- and polyfluoroalkyl substances (PFAS), and e-waste fall into regulatory grey areas or lack comprehensive, binding international enforcement mechanisms.

Addressing the Science-Policy Gap: A central theme of the policy brief is the establishment of an independent science-policy panel on chemicals, waste, and pollution prevention, similar to the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Selin argues that robust, peer-reviewed scientific syntheses are crucial for guiding international policymakers, establishing evidence-based safety thresholds, and preempting industrial pushback against chemical bans.

The brief emphasizes that global disparities in monitoring infrastructure severely weaken governance outcomes. Developing nations often bear a disproportionate burden of toxic waste dumping and industrial runoff while lacking the technical capacity, laboratory facilities, and financial resources needed to enforce strict safety standards. Selin calls for enhanced financial mechanisms, technical assistance, and technology transfer from high-income nations to bolster regulatory capacity across the Global South.

Roadmap for Future Governance: Looking ahead, Selin advocates for a systemic shift towards circular economy principles, green chemistry initiatives, and extended producer responsibility schemes. By holding chemical manufacturers accountable for the full life cycle of their products, global governance can transition from reactive pollution abatement to proactive risk elimination. The policy brief serves as a timely call to action for diplomats, researchers, and multilateral organizations striving to safeguard global public health and ecological stability against toxic degradation.
