4.6 Project Boundary
The spatial extent of the project boundary is defined in ACM0001 as the site of the project activity
where the gas is captured and destroyed/ used.
The following GHG sources are to be accounted as project emissions:
(a) If the electricity for project activity is sourced from grid or electricity generated by the landfill
gas captured would have been generated by power generation sources connected to the grid,
the project boundary shall include all the power generation sources connected to the grid to
which the project activity is connected.
(b) If the electricity for project activity is from a captive generation source or electricity generated
by the captured landfill gas would have been generated by a captive power plant, the captive
power plant shall be included in the project boundary.
