What is 'emission factor' in SAP EHS-CI - SAP Carbon Impact?

emission factor - Overview

• Component: EHS-CI

• Component Name: SAP Carbon Impact

• Description: A representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant. These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant for example, kilograms of particulate emitted per megagram of coal burned. The general equation for emissions estimation is: E = A x EF x 1-ER/100 where: E = emissions; A = activity rate; EF = emission factor, and ER = overall emission reduction efficiency, %

  Key Concepts: 
  Emission factor is a numerical value used to estimate the amount of a pollutant released into the atmosphere from a particular source. It is used in the calculation of the total emissions from a given source. In SAP Carbon Impact, emission factors are used to calculate the carbon dioxide equivalent (CO2e) emissions from a given source. 
  
  How to use it: 
  In SAP Carbon Impact, emission factors are used to calculate the CO2e emissions from a given source. The user can select an appropriate emission factor from the list of available emission factors in the system. The user can also create their own custom emission factors if needed. 
  
  Tips & Tricks: 
  When selecting an emission factor, it is important to consider the accuracy of the data and the relevance of the emission factor to the specific source. It is also important to ensure that the emission factor is up-to-date and reflects current regulations and standards. 
  
  Related Information: 
  The Intergovernmental Panel on Climate Change (IPCC) provides guidance on selecting appropriate emission factors for different sources. The US Environmental Protection Agency (EPA) also provides guidance on selecting appropriate emission factors for different sources.
