Predictive Emissions Monitoring Systems (PEMS) are software-analytical models that use automation data (DCS/PLC/SCADA/OPC) to predict concentrations and flows of pollutants in emissions. A properly implemented PEMS allows enterprises to reduce capital and operating costs, improve emissions management, and access real-time analytics.

Industry 4.0 is not magic but a set of technologies (IIoT, analytics, cloud, machine learning, AR, etc.) that connect data and physical processes. For industrial enterprises — from CHP plants to oil and gas assets — it is primarily a tool to improve reliability, reduce costs, and enhance environmental control.
