Ferroalloy production

Production-based methodology

The category /business/processes/production/ferroalloy/production contains data and a methodology based on generic emission factors for each ferroalloy type related to the quantity of ferroalloy produced. The methodology represents the Tier 1 (default values) approach described by the IPCC Guidelines for National Greenhouse Gas Inventories (NGGIP).

Raw materials-based methodology

The category /business/processes/production/ferroalloy/rawmaterials contains data and a methodology based raw material inputs to the ferroalloy production process. The methodology represents the Tier 2 and Tier 3 approaches described by the IPCC Guidelines for National Greenhouse Gas Inventories (NGGIP).

Ferroalloy methane emissions

The category /business/processes/production/ferroalloy/ch4 contains data and a methodology for calculating methane emissions associated with ferroalloy production. The methodology represents the Tier 1 and Tier 2 approaches described by the IPCC Guidelines for National Greenhouse Gas Inventories (NGGIP).
