Separate Reporting for Biogenic Carbon

In eTool, our LCI Sources starting from v17 have aligned with EN15804+A2 (2009) and reports the following environmental indicators separately.

Summary below, see EN15804 for more details:

  • Global Warming Potential Total (GWP): Total GWP equals the sum of the below indicators
  • Global Warming Potential Fossil (GWP F): 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.
  • Global Warming Potential Biogenic (GWP B): 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.
  • Global Warming Potential LULUC (GWP L): 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.

With our 2024 June (version 5.31.0) software release, users can now align how biogenic carbon is calculated at the end of life (all sequestered biogenic carbon is released) with EN15804+A2 by selecting the ‘EN15978 (EN15804+A2)‘ Calculation Standard in eTool. For more information on how to do this, please refer to the following support post: Calculation Standard.

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

1. Analysis Tab

One of the ways 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.

2. All Impact Details Report

You can also extract the biogenic data for your Design from the All Impact Details report in eTool. You can generate the report under the ‘Reports’ tab in your Design.

Open the excel file after you’ve downloaded it and you can find the information under the ‘Environmental Pivot Table’ or ‘Data Tab’ sheet.
