Amendments to two key pieces of National Greenhouse and Energy Reporting (NGER) legislation have been made that will affect reporting procedures for the FY15/16 reporting year.
The National Greenhouse and Energy Reporting (Measurement) Amendment Determination 2015 (No. 1) and National Greenhouse and Energy Reporting Amendment (2015 Measures No. 1) Regulation 2015 see a number of changes to the NGER reporting process.
Of critical importance is the change to the Global Warming Potential to Methane, which will increase from 21 tCO2-e to 25 tCO2-e. A common reportable substance in the solid waste and waste water sectors this will lead to a significant impact on emission profiles for businesses reporting in these sectors. The Global Warming Potentials, furthermore, for each NGER reportable greenhouse gas have been updated. Table 1 details each change.

We expect that all changes to emission factors will be incorporated into EERS. Reporters likely to be affected should incorporate the updated emissions factors into their calculations processes for continuous monitoring purposes.
Further changes are also detailed, in particular the annual updates to emission factors associated with electricity consumption. The changes for the Measurement Determination are detailed here and the Regulation are detailed here.
Both amendments do not apply for the FY14/15 reporting year.
