| Notes on dates | The source provides the following guidance on applying these factors to your GHG Inventory: |
-
By default EFs are effective for the calendar year
-
Where the reporting period ends part way through the calendar year, organisations should adopt the annual factors that cover the majority of the calendar year (e.g a period ending 31/03/23 would use the 2022 factors).
-
For reporting periods ending 30 June, entities should use the most recent calendar year’s EFs | | Release Frequency | Annual | | Sector | Multiple | | GHG Protocol Scope | Scope 1 Scope 2 Scope 3 | | GHG Protocol Sub-Category | Mobile Combustion Stationary Combustion Fugitive Emissions Electricity Scope 2: Other Purchased Goods and Services Capital Goods Fuel- and energy-related activities Transportation and distribution Waste Generated in Operations Business Travel Employee Commuting End-of-Life Disposal | | Type of Data | Activity Based | | Boundary | Cradle-to-Gate Well-to-Tank Combustion | | GHG Outputs | CO2e CO2 (limited) CH4 (limited) NO2 (limited) | | Spend-Base Info | | | Source Currency | N/A | | Time Value Base Year | N/A | | Transformations in Source Data | N/A | | Inflation adjusted by Sumday by default | N/A | | Data Quality | | | Data Quality assessed quantitatively by Source | No | | What the source says about its data quality | Source publishes a detailed methodology paper with each release, however data quality or uncertainty has not been qualified by the source. | | Sumday’s take | The emissions factors published by UK DESNZ are activity based factors, compiled by a reputable governmental source and are released frequently ensuring changes in the latest scientific understanding are incorporated. These factors would indicate a relatively high level of data quality, however it is important to note that they are still based on average data and that judgement should always be used in in the selection of emissions factors, especially if the dataset does not directly relate to geographic | | License | | | Type of License | Open Government License | | License URL | Link | | Sumday’s take | Use these factors to your hearts content, just remember to cite the good folks in the UK government |
