A self contained field sampling system for measuring engine exhaust emissions includes a mini-dilution tunnel adapted for the collection of proportional samples of emissions to be analyzed, an engine air intake flow measurement instrument, a system controller and data acquisition system, and an optionally portable generator to provide electrical power. Several probes withdraw dilute and undiluted exhaust for emission analysis. Various engine emissions may be isolated. As well, engine emissions mass rate may be calculated by reference to engine RPM, inlet flow rate, exhaust temperature and emissions output rate.

Emissions Management is designed to support all emissions relevant processes in large industrial corporations. This comprises the provision of functionality required on operational level for single plants and facilities as well as for corporate demands. It involves three roles, which includes emissions manager, emissions administrator and corporate compliance manager. They integrate people and processes across different business units on high quality level thereby, contributing significantly to risk mitigation. It is needed to manage and reduce their emissions of greenhouse gases following the ratification of the Kyoto Protocol.
