Reference Answer
### Introduction to EEDI
The Energy Efficiency Design Index (EEDI) is a technical measure mandated by the International Maritime Organization (IMO) under MARPOL Annex VI, Chapter 4. It aims to promote the use of more energy-efficient equipment and engines in new ships. The EEDI is a non-prescriptive, performance-based mechanism that leaves the choice of technologies to the industry. For a new ship to be certified, its calculated EEDI must be below a specific regulatory limit.
This framework is built upon two core concepts: the **Required EEDI**, which acts as the regulatory benchmark, and the **Attained EEDI**, which is the actual calculated value for a specific ship.
