Overview
UNEP is the UN Environment Programme, the United Nations body responsible for the environment. It sets the global agenda on environmental issues and provides the home for many of the international agreements that govern chemicals and waste.
Several of those agreements sit under its wing. UNEP hosts the Stockholm Convention on persistent organic pollutants, the Minamata Convention on mercury and the Basel Convention on the transboundary movement of hazardous waste.
Why it matters for products
The treaties UNEP hosts set the starting point for EU law. When the Stockholm Convention lists a substance, the EU writes it into its POP Regulation, which bans or limits persistent organic pollutants in products across the bloc. The same path runs from the Minamata and Basel conventions into EU rules on mercury and waste, so a global decision taken under UNEP can end up as a duty you have to meet on a specific product.
