The Department of Energy and Climate Change (DECC) produce and publish a range of emissions factors, some in partnership with Department for Environment, Food and Rural Affairs (Defra) for many greenhouse gas emitting activities.
For electricity generation, there are a range of different emissions factors used by different policy areas, such as:
- The UK’s Greenhouse Gas Inventory
- The EU-ETS
- DECC/Defra Company reporting factors
- Climate Change Agreements (CCA)
- The CRC Energy Efficiency Scheme
- Fuel Mix Disclosure
The aim of this note is to explain the differences between these electricity emissions factors and the reasons for these differences.
