NEA is proposing to control 18 types of Hydrofluorocarbons (HFCs) under the Second Schedule of the Environmental Protection and Management Act (EPMA). Under the proposed control, companies importing or exporting the listed HFCs, whether in pure or mixture forms, are required to obtain a Hazardous Substances (HS) licence from NEA (Pollution Control Department). Licence holders are required to comply with the stipulated licensing conditions.
The 18 types of HFCs that will be listed in Second Schedule of EPMA are as follows:
