Technical Paper | Electricity-specific emission factors ...

To give an example, the emission factor for UK grid electricity in 2009 is 0.48322 kgCO. 2. per kWh generated (Defra 2011a), and so if a company uses 1,000 kWh of grid electricity the associated Scope 2 emissions are 483.22 kgCO. 2. . Country-specific emission factors for grid electricity are published for some countries, for example

Emission intensity - Wikipedia

Particularly for non-CO 2 emissions, there is often a high degree of uncertainty associated with these emission factors when applied to individual countries. In general, the use of country-specific emission factors would provide more accurate estimates of emissions than the use of the default emission factors.

Emission intensity - Wikipedia

Emission factors assume a linear relation between the intensity of the activity and the emission resulting from this activity: Emission pollutant = Activity * Emission Factor pollutant. Intensities are also used in projecting possible future scenarios such as those used in the IPCC assessments, along with projected future changes in population, economic activity and energy technologies.
