Environmental crime is one of the most profitable areas of international criminal activity. Criminal organisations earn approximately $10-12 billion per year for dumping waste. Growing international concerns regarding these types of environmental crimes have led to several global Multilateral Environmental Agreements; the Stockholm, Basel and Rotterdam Convention. Building on the Multilateral Environmental Agreements, the Regional Enforcement Network for Chemicals and Waste, (REN) was set- up with the aim to build a network for improved cooperation and capacity building of front line officers on national and regional levels to reduce illegal transboundary movement of chemicals and waste. 
Sida has provided financial support to the Regional Enforcement Network for Chemicals and Waste (REN) program with 11 million SEK from 2011-2018.  The overall goal of the program has been to reduce unwanted trans boundary movement of hazardous chemical and waste in Asia by preventing illegal trade and encouraging legal trade. Through the improved enforcement cooperation regionally and globally and the targeted problem- solving capacity building at the national level through a network, the program enabled enforcement officers to monitor and control trans boundary movements of chemicals and waste more efficiently.  
REN had five priority areas within the framework of the objective 1) Technical assistance for problem-solving2) Information and intelligence sharing 3) Enforcement operations and the Asia Environment Enforcement Award 4) Networking and awareness 5) Partnership for sustainability
REN consisted of a network of 25 countries across North-East, South and South-East Asia coordinated by UN Environment. Example of countries in the network were Cambodia, Thailand, India, Indonesia, Malaysia, China and Vietnam.
