2 emissions are measured in pounds per hour using both an SO 2 pollutant concentration monitor and a volumetric flow monitor. For NO x, both a NO x pollutant concentration monitor and a diluent gas monitor are used to determine the emissions rate in weight per volume or weight per heat value (for example lbs/million Btu, lbs/ft 3, kg/kWh or kg ...
An emission inventory (or emissions inventory [1]) is an accounting of the amount of pollutants discharged into the atmosphere.An emission inventory usually contains the total emissions for one or more specific greenhouse gases or air pollutants, originating from all source categories in a certain geographical area and within a specified time span, usually a specific year.

Pillar 3 – Secondary armament with, for example, guided missiles (French lead) Pillar 4 – Communication, command and deployment system (French-German lead)
A CATI PEMS being strapped down inside a vehicle. A portable emissions measurement system (PEMS) is a vehicle emissions testing device that is small and light enough to be carried inside or moved with a motor vehicle that is being driven during testing, rather than on the stationary rollers of a dynamometer that only simulates real-world driving.
Google, H&M, Stripe and other members of the climate-focused Frontier coalition will buy $80 million of carbon credits from a firm using oil industry technology to capture paper mill emissions and ...
It is the first improved analyzer that is able to detect more than one component of a sample gas at one time. Earlier analyzers were held back by the fact that a particular gas also has lower absorption bands in the infrared. The invention of 1975 has as many detectors as the number of gases to be measured.
