RESEARCH ON DEVELOPING A GREENHOUSE GAS EMISSION REDUCTION SCENARIO IN THE STEEL PRODUCTION SECTOR IN VIETNAM

Abstract

The study presents a greenhouse gas (GHG) emission reduction scenario for the steel industry based on calculating the emissions using specific emission factors. This forms the basis for constructing a baseline scenario and an emission reduction scenario for the steel production sector from 2015 to 2030. The results indicate that in the baseline scenario, emissions increase significantly from over 5 million tons CO₂tđ in 2015 to over 64 million tons CO₂tđ in 2030. Specifically, emissions from BF-BOF increase from over 4 million tons CO₂tđ to over 63 million tons CO₂tđ, and emissions from EAF increase from over 0.5 million tons CO₂tđ to over 1 million tons CO₂tđ. This can be explained by the crude steel production, which was 5.647 million tons in 2015 and is projected to reach 32.5 million tons in 2030. With a moderate reduction scenario, applying technological solutions in energy and fuel savings, including solutions for EAF electric arc furnace energy and fuel savings, coke oven energy and fuel savings, and iron and steel refining energy and fuel savings, the GHG emissions are reduced by over 18 million tons CO₂tđ compared to the baseline scenario.
