Reference

This section describes all available custom functions provided by IBM Envizi for Excel.

Each function calls the IBM Envizi Emissions API from Excel to calculate greenhouse gas (GHG) emissions based on provided inputs.

General Notes

  • All functions must be entered directly into Excel cells.

  • Arguments in square brackets ([ ]) are optional.

  • Errors are returned as Excel error messages.

  • Units must follow the supported unit conventions defined in Envizi.
