Platinum Group Metals:

• Data is presented from the mine perspective, providing a complete view of supply chain emissions associated with the production of PGMs from mining, refining, base metal and PGM concentrate smelting
• Smelting emissions for PGM concentrates vary considerably, depending upon the composition of the concentrate (high/low chrome, Merensky/UG2/Platreef/other ores).  In our methodology base metal concentrate smelting emissions are fully allocated to the primary base metal in concentrate with precious metals being free-carried. Refining emissions are allocated based on 6E production output
• Includes emissions for minority shareholdings which are often excluded in company sustainability reports

Emission data is presented as total tonnes of CO₂e and tonnes of CO₂e per ounce of PGM.

Users can view data on a platinum, palladium or rhodium equivalent basis, or on a 4E or 6E PGM production basis. Data is also available for ruthenium and iridium.

For PGMs  E₀ and E₁ emissions are defined as: 

E₀: Scope 1 and 2 emissions at mine site.

E₁: E₀ plus emissions from concentrate freight, smelting and refining to produce refined PGM metals.
