- Complete view of GHG emissions associated with the production of saleable coal, presented from the mine perspective
- Like-for-like comparison of thermal and metallurgical coal through carefully defined supply chain system boundaries
- Includes physical production parameters, including tonnages of ROM coal, met coal for export, thermal coal and total saleable coal
- Emissions are accounted for by energy source. Methane emission estimates are based on best available data. The product includes a tool for flexing methane Global Warming Potential (GWP) assumptions
Emission data is presented as total tonnes of CO2e and tonnes of CO2e per tonne of saleable coal (thermal + metallurgical).
For our metallurgical coal model E0 and E1 emissions are defined as follows:
E0: Emissions at mine site from mining and processing.
E1: E0 plus freight emissions to port of delivery.
The analysis provides comprehensive coverage of seaborne metallurgical coal market. This includes exports from Australia, Brazil, Canada, Mozambique, Mongolia and USA and Russian production.
All assets include emissions to the port at final country of import. For mines in Australia, all metallurgical coal exports are to China. For other countries, a typical export split is assumed between Europe, Americas and Asia based on government / company export statistics.
Fugitive emissions. These are as reported, or benchmarked based on location of mine and mining method (surface / underground Methane capture and flaring are netted off Scope 1 emissions. Clients can flex Global Warming Potential (GWP) factors for methane from those reported by a company to the latest GWP factors. Carbon credits from methane capture and flaring are netted off from Scope 1 emissions.
Emission intensities are on coal production basis. Intensities are calculated at each mine by dividing total Scope 1 & 2 emissions by total saleable coal production, both thermal and metallurgical coal.
