Not applicable to this type — never a gap in our current method

The criterion does not apply to this methodology. Our current method never counts it as a gap.

  • Grid emission factorCM-N-GRID-EF
  • Buffer poolCM-N-BUFFER
  • Fraction of non-renewable biomass (fNRB)CM-N-FNRB
  • Usage rate of the devicesCM-N-USAGE
  • Tracking of the end useCM-N-END-USE-TRACKING

The general rules apply as well. Read the general rules.
