25  Interactive effects
 (1) The project proponent must identify the interactive effects and interactive equipment for each implementation.
 (2) If a change in emissions is an interactive effect for the baseline measurement period, the change is to be treated as an interactive effect for each reporting period for the implementation.
Note: For the purposes of calculating emissions abated by the implementation under Part 4, a change in emissions that is either a reduction in emissions or an immaterial or minor increase in emissions may be accounted for within the boundary for the implementation or identified as an interactive effect.
As required under subsection 19(2), a change in emissions that is a material increase in emissions must be accounted for within the boundary for the implementation if it was reasonable to expect an emissions change of this kind as a result of having undertaken the implementation.
If, as a result of undertaking the implementation, there is an increase in emissions outside of the boundary for the implementation that could not reasonably have been expected, that emissions change must be accounted for as an interactive effect unless it can be excluded under section 43.
 (3) For each interactive effect, the project proponent must choose an approach for estimating the interactive effect that:
 (a) uses data from the records of the site of the implementation; and
 (b) uses either:
 (i) regression baseline emissions modelling or engineering baseline emissions modelling that is consistent with this determination; or
 (ii) a generally accepted energy efficiency measurement and verification practice that applies to changes of that kind; and
 (c) is consistent with relevant measuring and estimation requirements under the NGER (Measurement) Determination that apply to the combustion of fuel, consumption of electricity and production of industrial process emissions; and
 (d) results in an estimate that is measurable, capable of being verified and conservative; and
 (e) is credible and robust.
 (4) However, in estimating the interactive effect using an approach chosen in accordance with subsection (3), the project proponent must:
 (a) work out emissions factors for each greenhouse gas j released due to the consumption of fuel type i using the approach that applies for working out EFi,j in section 53; and
 (b) work out the energy content factor of fuel type i using the approach that applies for working out ECi in section 53; and

 (c) work out emissions factors for the consumption of electricity using the approach that applies for EFElec in section 53; and
 (d) work out industrial process emissions using the approach that applies for EProc,h,m  in section 53.
