AHMEDABAD: The implementation of the ambitious emission trading scheme (ETS) for Narol industrial units to curb particulate matter (PM) 2.5 emission has slowed down significantly. One of reasons is availability of semiconductors required to assemble the Continuous Emission Monitoring System (CEMS) — which is the key instrument required for the ETS.
The machine consists of a combination of sensors and flow meters. Senior Gujarat Pollution Control Board (GPCB) officials said that 119 CEMS machines were planned for installation across industrial units, but only 98 sensors and 70 odd flow meters could be arranged. “The company installing CEMS machines imports it from Germany. But since China supplies some key semiconductor components for this instrument, there are issues with the assembly of the instruments,” said the senior GPCB official.
