End-of-Life Recycling GHG

Emissions from ship recycling - towing to yard, beaching or dry-docking, dismantling, steel recovery, waste disposal. Net balance is usually NEGATIVE (CO₂ avoided) because recovered scrap steel displaces virgin blast-furnace steel.

Formula, assumptions, and limits

\text{Net} = \text{CO}_2^\text{tow} + \text{CO}_2^\text{yard} - m_\text{scrap} \cdot (\text{EF}_\text{BF-BOF} - \text{EF}_\text{EAF})

Symbol	Meaning	Unit
$\text{CO}_2^\text{tow}$	CO₂ from final tow	t
$\text{CO}_2^\text{yard}$	Yard operations CO₂	t
$m_\text{scrap}$	Recovered scrap steel	t
$\text{EF}_\text{BF-BOF}$	Virgin steel emission factor (BF/BOF)	t CO₂ / t
$\text{EF}_\text{EAF}$	Scrap-based EAF emission factor	t CO₂ / t

In short

End-of-life GHG balance - tow-fuel CO₂ + yard operations vs scrap-steel credit.
