Reference Answer
### Introduction to GHG Ratings in Shipping
Greenhouse Gas (GHG) ratings are standardized metrics used to assess and regulate the environmental performance of ships, primarily focusing on Carbon Dioxide (CO₂) emissions, which constitute the majority of GHGs from shipping. With the maritime industry contributing approximately 3% of global GHG emissions, the International Maritime Organization (IMO) has implemented a comprehensive regulatory framework to drive down this environmental impact. These ratings are not merely for compliance; they are critical commercial differentiators influencing a vessel's charterability, operational costs, and overall market value.
### Types of GHG Ratings in International Shipping
The IMO has established a multi-faceted approach to regulate GHG emissions, targeting different aspects of a ship's lifecycle and operation.
