Gold

• Data is presented from the mine perspective, including supply chain emissions up to  production of refined gold
• Physical production parameters are presented, including ore mined, heap leached and/or milled, ore grades, strip ratios and by-product metal production
• For base metal concentrates containing gold, emissions are fully allocated to the primary metal in concentrate with gold being free-carried, up to the anode slime stage. Emissions from refining of anode slimes are allocated to gold
• Allocation of emissions by company is added according to equity ownership of mine assets, including emissions for minority shareholdings, which are often excluded from company sustainability reports)
• The dataset includes total cash costs and all-in sustaining costs,  based on the World Gold Council Guidelines

Emission data is presented as both total tonnes of CO₂e and tonnes of CO₂e per equivalent ounce of refined gold.

For gold, E₀ and E₁ emissions are defined as follows: 

E₀: Scope 1 and 2 emissions at mine site.

E₁: E₀ plus emissions from dore and concentrate freight, smelting and refining.
