Reference Answer
### **Introduction**
International shipping is responsible for approximately 3% of global Greenhouse Gas (GHG) emissions, primarily Carbon Dioxide (CO₂) from the combustion of marine fuels. In response, the International Maritime Organization (IMO), under MARPOL Annex VI, has implemented a comprehensive regulatory framework to mandate and measure the energy efficiency of ships. GHG Ratings have thus become a critical benchmark for regulatory compliance, commercial viability, and environmental stewardship. These ratings evaluate a vessel's efficiency from its design phase through to its operational life.
