DENR-EMB issues Chemical Control Orders (CCOs) that prohibit, limit, or regulate the use, manufacture, import, transport, processing, storage, possession, and wholesale of those priority chemicals that DENR-EMB determined to be regulated, phase-out, or banned because of the serious risks they pose to public health, workplace, and environment. At any one time, DENR-EMB may impose a regulation, a phase-out plan, or a ban on a chemical or chemical substance when it determines that such action is necessary.

Chemicals and chemical substances that pose an unreasonable risk to public health or the environment are potentially subject to CCOs. Each year, after due consideration to industrial needs, the health and environment risks, the Philippine commitment to international and regional treaties and conventions, and DENR-EMB’s capabilities and resources to manage the controlled chemicals, DENR-EMB may determine what chemicals listed as priority (PCL) should be regulated, controlled, or phase out.
