CSUKEEIO Scope 3 Factors
Carbon Saver Climate Researchers have created the CSUKEEIO (Carbon Saver UK Environmentally Extended Input Output Model) using an extensive catalog of the latest official UK government statistics.
The CSUKEEIO forms the basis of our Scope 3 Footprinting Tools. It is the most complete, uptodate, timeseries dataset for UK organisations to calculate their scope 3 emissions. They cover emissions sources based on the Climate Change Act, which are used to by the UK government to monitor progress towards Net Zero targets.
Environmentally-extended input output (EEIO) models
Environmentally-extended input output (EEIO) models estimate energy use and/or GHG emissions resulting from the production and upstream value chain activities of different sectors and products within an economy. The resulting EEIO emissions factors can be used to estimate GHG emissions for a given industry or product category. EEIO data are particularly useful in screening emission sources when prioritizing data collection efforts.
EEIO models are derived by allocating national GHG emissions to groups of finished products based on economic flows between industry sectors. EEIO models vary in the number of sectors and products included and how often they are updated. EEIO data are often comprehensive, but the level of granularity is relatively low compared to other sources of data.
The Carbon Saver UKEEIO carbon factors for Scope 3 emissions are based on the latest available official UK Government statistics. Our Climate Scientists have done the hard work to make your scope 3 footprinting straightforward
Data Sources
When choosing a set of Scope 3 Factors ensure they are:
- Based on official, credible statisitics and data
- Geographically relevant eg. Grid Electricity UK = 0.21 is half the USA = 0.42 which is half South Africa = 0.90. Therefore UK Scope 3 Factors with have less carbon intensity than the USA or South Africa etc.
- Factors take imports and exports into account
- Updated annually to reflect changes in carbon intensity, eg. electricity decarbonisation, resource and energy efficiency, etc.
- Factors are available for multiple years so you can set a base year and model your Scope 3 Emissions reductions
- The same data set is consistantly applied each year to quantify reduction trends towards Net Zero
- Do not mix and match factors between years otherwise the results will be like comparing apples with pears
The Carbon Saver UKEEIO Model meets all of these requirements and are available for the last 22 years (2000 to 2022)
