Reference Answer

### (a) International Maritime Organization (IMO) Data Collection System (DCS)
The IMO Data Collection System (DCS) for fuel oil consumption of ships is a regulatory framework established under MARPOL Annex VI, Regulation 22A. Its primary objective is to collect standardized data on fuel consumption, which can be used as a basis for future policy decisions to enhance energy efficiency and reduce greenhouse gas (GHG) emissions from international shipping.
#### (i) Applicability of Ship Size (GT)
The IMO DCS regulation applies to all ships of **5,000 Gross Tonnage (GT) and above** engaged in international voyages. This threshold ensures that the regulation covers the vast majority of the fuel consumed by the international shipping fleet, as larger vessels are disproportionately responsible for total emissions.
