an overview of available emission estimation methods and an example showing the application of different techniques to estimate emissions for a paint manufacturing facility. Note that the use of site-specific emissions data is always preferred over the use of default values developed through use of industry emission averages.
Introduction Climate change is an urgent global challenge. Reduction in global greenhouse gas (GHG) emissions of 41–72% by 2050 and 78–118% by 2100 compared with the level in 2010 are required to maintain the temperature change below 2 °C relative to pre-industrial levels. 1 The current society heavily relies on metals for a …

An emission factor relates the quantity (weight) of pollutants emitted to a unit of source activity. Emission factors reported in AP-42 are used to: 1. Estimate areawide emissions. 2. Estimate emissions for a specific facility. 3. Evaluate emissions relative to ambient air quality. This report provides background information from test reports ...
