Ferroalloy production

The category business/processes/production/ferroalloy for calculating greenhouse gas emissions from ferroalloy production. These methodologies are sourced from the IPCC Guidelines for National Greenhouse Gas Inventories (NGGIP). See the following subcategories for further details.

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).
