The GHG Protocol encourages New Zealand organisations to use dual reporting & the BraveTrace Residual Supply Factor. The Greenhouse Gas Protocol (GHGP) is the most widely used framework for measuring GHG emissions. For New Zealand organisations, adherence to the GHG Protocol’s dual reporting requirements is essential for accurate greenhouse gas (GHG) emissions reporting. According to the protocol, organisations “shall” report their Scope 2 emissions—those related to purchased electricity—using both the location-based method and the market-based Method.
