eTool – LCI Source V.17, V18 and latest V19 are aligning with EN15804 2019 A2 and reports the following environmental indicators separately.
Summary below, see EN15804 for more details:
- GWP Total: Total GWP equals the sum of the below indicators
- GWP Fossil: GWP from the oxidation or reduction of fossil fuels or materials containing fossil carbon (e.g. combustion, incineration, landfilling, etc.). This indicator also accounts for GWP from GHG emissions e.g. from peat and calcination as well as GHG removals e.g. from carbonation of cement-based materials and lime.
- GWP Biogenic: GWP from removals of CO2 into biomass from all sources except native forests, as transfer of carbon, sequestered by living biomass, from nature into the product system declared as GWP-biogenic.
- GWP LULUC: This indicator accounts for GHG emissions and removals (CO2, CO and CH4) originating from changes in the defined carbon stocks caused by land use and land use changes associated with the declared/functional unit.

Biogenic Carbon reporting in eTool automated LCA report
Global Warming Potential Biogenic (GWP B) is reported as a separate indicator in eTool automated LCA report.
In addition, when reporting the total Global Warming Potential (GWP), the Highest and Lowest Impact Materials and Templates tables now include Biogenic Carbon.
How to extract Biogenic Carbon data from eTool
The best way to extract the biogenic carbon data from eTool is to use the Analysis tab. However in order to do that, you’ll first need to turn on these indicators for your project in the Project level’s ‘Indicator’ tab. Please note that these indicators are only available in LCI datasets v17 and later. If you do not have access to this, please submit a Support Request.
Once these indicators have been turned on, navigate to the ‘Analysis’ tab in your design and change the reported impacts to the biogenic indicators by clicking on ‘Load All Impacts’.
You can use the ‘Custom’ button to generate a customised table to display the data as you need. For more guidance on how to use the Analysis tab, please refer to Module 6 of the Intermediate Course.
