EPA iron and steel production methodologies

The category at business/processes/production/ironandsteel/epa provides methodologies for calculating greenhouse gas emissions associated with the production of iron and steel. These methodologies are sourced from the guidelines published by the Climate Leaders industry-government initiative for reporting and reducing greenhouse gas emissions.

See the following subcategories for further detail.

Primary production

The category at /business/processes/production/ironandsteel/epa/primary provides a methodology for calculating greenhouse gas emissions associated with the production of primary iron and steel. This methodology accounts for the CO₂ emissions due to carbonate calcination and adjusts stationary combustion emissions by accounting for carbon which remains contained within process products or by-products.

The category at /business/processes/production/ironandsteel/epa/eaf provides a methodology for calculating greenhouse gas emissions associated with Electron Arc Furnace (EAF) steel facilities. This methodology accounts for the CO₂ emissions due to carbonate flux and the use of carbon electrodes. Any emissions from coke and/or coal consumption should be calculated using a methodology for stationary combustion.
