Calculators

Emissions and energy threshold calculator

The GHGR threshold calculator is designed to assist users in determining their GHGR obligations. 

It enables estimation of scope 1 and scope 2 emissions, energy production, and energy consumption.

To facilitate optimal use of the calculator, we provide a user guide, which can be downloaded for reference.

Uncertainty calculator

The GHGR uncertainty calculator is designed to assist in the assessment and reporting of uncertainty associated with scope 1 emissions. It can be employed by those utilising methods beyond method 1 for the reporting of fuels or energy sources. Furthermore, it can be utilised by those required to calculate uncertainty using non-default values.

The Emissions and Energy Reporting System (EERS) automatically calculates uncertainty associated with scope 1 emissions where method 1 has been employed.

Solid waste calculator

The GHGR solid waste calculator can help you assess the greenhouse gas emissions from landfill operations.

Domestic and commercial wastewater calculator

The GHGR wastewater domestic and commercial calculator can help you assess the greenhouse gas emissions from domestic and commercial wastewater.
