Emission factors – what are they and what are they for?

What are emission factors?
Carbon emission factors, sometimes called carbon conversion factors, are used to calculate the carbon emissions arising from an activity. For the greatest accuracy, the best way to measure carbon emissions would be to monitor them directly as they are emitted, for example by placing a sensor in a power station chimney.  Given the large number of different sources of carbon emission that can be associated with a particular activity, this method would quickly become impractical.  To simplify the calculation, emission factors were developed by measuring the average carbon emissions associated with a particular activity. 
Given the complexities of measuring carbon emissions directly, developing emission factors is a technical and scientific challenge.
