High-Emitter Identification Service (HEIS)

A fleet auditing service that uses automated Plume Chasing to screen vehicles in real-world driving and identify the small percentage of 'super-emitter' vehicles responsible for most fleet pollution. New evidence strengthens the case: real-world emissions often exceed certification limits even on modern SCR-equipped trucks, and current in-use compliance tests sample only a small fraction of engine operation. Because PEMS remains the reference method in EU legislation, the service works as a screening layer whose 'hit list' is confirmed by low-cost on-board sensors or PEMS before any enforcement or decommissioning action.
