Data is presented from the mine perspective, including physical production parameters such as ore mined and ore grades, plus mining method and deposit type.
Coverage of lead smelter GHG emissions is in development
Emission data is presented as total tonnes of CO2e and tonnes of CO2e per tonne of lead equivalent production.
Lead mine E0 emissions are defined as Scope 1 and 2 emissions from mining activities and ore processing at the mine site.
Downstream emissions for lead smelting and refining will be available in future versions of the product, allowing for a full E1 intensity analysis.
Scope 1 (Direct) Greenhouse Gas Emissions are derived from sources that are owned or controlled by the reporting organisation – often to the ‘minegate’ boundary or smelter/refinery gate for integrated operations. They typically include emissions from consumption of diesel in haulage trucks or onsite power generators along with emissions from other sources such as natural gas, aviation fuel, fugitive emissions, use of explosives, etc. Intensity numbers are calculated as total tonnes of CO2e divided by lead metal equivalent production.
Scope 2 (Indirect) Greenhouse Gas Emissions are generated at sources owned or controlled by another organisation. This is generally electricity purchased by the mine (or smelter for integrated assets) from the grid. The Grid Carbon Factors sheet in this model provides a high level summary of the grid emission data.
