The factors help to estimate emissions from various sources of air pollution. In most cases, the factors are simply averages of all available data of acceptable quality, and are generally assumed to be representative of long-term averages. The equation for the estimation of emissions before emission reduction controls are applied is: E = A × EF
The Emissions & Generation Resource Integrated Database (eGRID) is a comprehensive source of data on the environmental characteristics of almost all electric power generated in the United States. eGRID is issued by the U.S. Environmental Protection Agency (EPA).
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 ...
Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry. Methane and nitrous oxide are measured by other instruments.
[7] [8] [2] This means that for specific amount of cumulative CO 2 emissions, a known global temperature change (within a range of uncertainty) can be expected, which indicates that holding global temperature change to below specific thresholds is a problem of limiting cumulative CO 2 emissions, leading to the idea of a carbon budget.

Organizations will often set an emissions baseline, create targets for reducing emissions, and track progress towards them. The accounting methods enable them to do this in a more consistent and transparent manner. The main reasons for GHG accounting are to address social responsibility concerns or meet legal requirements. Public rankings of ...

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.
