MARITIME – POLLUTION PREVENTION & ENVIRONMENTAL CALCULATOR
Eedi Calculation
A precise tool.
What is the Eedi Calculation & How does it work?
The Energy Efficiency Design Index (EEDI) is an internationally recognised metric that quantifies the CO₂ emissions per unit of cargo transport for new ships. It encourages ship designers to adopt technologies and operational strategies that reduce fuel consumption and greenhouse‑gas output throughout the vessel’s life‑cycle.
EEDI is calculated by comparing the ship’s installed engine power with its cargo‑carrying capacity, adjusted by a capacity factor that reflects the vessel type and its design speed. A lower EEDI value indicates a more efficient design, helping operators meet tightening IMO carbon‑reduction targets.
By entering the ship’s key parameters below, the calculator applies the standard EEDI formula and instantly shows the resulting index. Designers can iterate values such as power, deadweight tonnage, or capacity factor to explore trade‑offs and achieve compliance with the latest environmental regulations.
EEDI = frac{C times P}{DWT}
C = capacity factor (depends on ship type and design speed)
P = installed engine power (kW)
DWT = deadweight tonnage (tonnes)
P = installed engine power (kW)
DWT = deadweight tonnage (tonnes)

Frequently Asked Questions
What is EEDI and why is it important?
EEDI stands for Energy Efficiency Design Index. It measures CO₂ emissions per unit of cargo transport, encouraging ship designers to reduce fuel consumption and greenhouse gas output.
How do I calculate my ship's EEDI?
To calculate your ship's EEDI, input the installed engine power, cargo-carrying capacity, and vessel type into our calculator. The tool will adjust for a capacity factor based on these details.
Does EEDI apply to all types of ships?
EEDI applies to new ships built after January 1, 2015, and is designed to encourage efficiency improvements across various vessel types.
How does the capacity factor affect EEDI calculations?
The capacity factor adjusts the cargo-carrying capacity based on the ship's type and design. This ensures that different vessel types are compared fairly in terms of energy efficiency.
Can I use this calculator for existing ships?
This calculator is specifically designed for new ships built after January 1, 2015. For existing ships, refer to the International Maritime Organization's guidelines on EEDI.
What are the benefits of reducing a ship's EEDI?
Reducing a ship's EEDI leads to lower CO₂ emissions, improved fuel efficiency, and potentially reduced operational costs. It also contributes to global efforts in combating climate change.
Where can I find more information about EEDI regulations?
For detailed information on EEDI regulations, visit the International Maritime Organization's website or consult maritime law resources specific to your country.
