The Regional Enforcement Network for Chemicals and Waste (REN)  is a project financed by the Swedish International Development Cooperation Agency (SIDA) and implemented by UN Environmnet in 25 countries in Northeast Asian, South Asia and Southeast Asia (including Afghanistan, Bangladesh, Brunei, Bhutan, Cambodia, China, Fiji, India, Indonesia, Iran, Republic of Korea, Democratic Republic of Korea, Lao PDR, Malaysia, Maldives, Mongolia, Myanmar, Nepal, Pakistan, Philippines, Singapore, Sri Lanka, Thailand, Timore Leste, and Vietnam). The Project focused on the prevention and control of illegal transboundary movements of harmful substances and hazardous wastes (HSHW). It aims to reduce illegal trans-boundary movement of harmful chemicals and hazardous waste through improved capacity of frontline enforcement officials for combating illegal traffic of HSHW, and enhanced cooperation at both the national and regional levels for effective enforcement of chemical and waste related multilateral environmental agreements (MEAs).
REN is a project to set up an informal network serving as a platform on information exchange and experience sharing for the participating countries as well as the partners in order to enhance the capacity of the participating countries for improved prevention and control of illegal transboundary traffic of wastes and chemicals, should countries wish to be engaged in the network.
The activities of the project include: technical assistance for problem-solving, information and intelligence sharing, enforcement operations and Asia Environmental Enforcement Award, networking and awareness, partnership for sustainability. 
UN Environment as the Implementing Agency will oversee the execution of the project jointly with the project’s Coordinating Agencies through the mechanism of an Advisory Group. Activities will be implemented by UN Envrionment in collaboration with partner agencies that are carefully selected for each technical merit and operational capability, significantly enhancing the outreach of this project and the sustainability of regional enforcement networking beyond the life of this project. 






With the funding of Swedish International Cooperation Development Agency (Sida), The project“Multilateral Environmental Agreements Regional Enforcement Network (MEA-REN)” was initiated in 2007 to cover substances and goods that are controlled by all four MEAs concerning harmful substances and hazardous waste including the Montreal Protocol, the Basel Convention, the Rotterdam Convention and the Stockholm Convention. 

The project was successfully implemented during 2007-2011, and series of results had been achieved in terms of capacity buiding, information sharing and awareness raising in the participating countries in Asia.
