| Description | The German Federal Ministry for Housing, Urban Development, and Building provides the OEKOBAUDAT, an extensive database of emission factors for materials and equipment used in construction and building design. |
| Source type | Governmental |
| Original dataset URL | URL |
| Year released | 2024 |
| Geography | Multiple regions |
| Sector | |
| Type of data | Activity-based |
| Emission results | CO2e |
| Data Transformation | The source reports emissions in terms of CO2e per unit of product, where the unit varies (e.g., kg, m3 etc). To ensure consistency within our database, this data has been normalized to CO2e per standard unit (e.g., per 1 kg, per 1 m3 etc). This normalization is achieved by dividing the reported CO2e values by their respective reference sizes, regardless of the unit of measurement. |

| Methodology description | Oekobaudat follows EN 15804:2012+A2:2019 "Sustainability of construction works. Environmental product declarations. Core rules for the product category of construction products". There are three components to each total emission factor: Total = fossil + biogenic + land use land-use change The source fields are GWPtotal, GWPfossil, GWPbiogenic, GWPluluc EN 15804 is one of the few standards that requires biogenic carbon dioxide emissions and removals to be included; it follows a "-1/+1" approach whereby removals (into biomass) are multiplied by -1 and subsequent emissions (e.g. through combustion) are multiplied by 1. This is in contrast to the usual "neutral" approach which multiplies both by 0. This is particularly relevant to timber and products derived from biomass used in construction; the total emission factor will include the carbon dioxide captured as carbon in the product. This means that the total emission factor will be lower than under the neutral approach and may be negative where biogenic removals exceed fossil and land use change emissions. This means that Oekobaudat emission factors are typically not suitable for corporate reporting. |
| Limitation / key issues to note | Oekobaudat follows the EN 15804:2012+A2:2019 standard which requires a -1/+1 approach to biogenic carbon dioxide. This means that the emission factors are generally not suitable for corporate reporting. |
