Back
The nautical industry is undergoing a profound transformation driven by new international regulations aimed at reducing the environmental impact of ships. These regulations, spearheaded by the International Maritime Organization (IMO), are designed to decrease greenhouse gas emissions, primarily CO2, and enhance energy efficiency in vessels.
Context of the New Regulations
The most significant changes include the adoption of the EEXI (Energy Efficiency Existing Ship Index) and the CII (Carbon Intensity Indicator). Both mechanisms focus on controlling and reducing carbon dioxide emissions from ships. These standards mainly apply to vessels with a gross tonnage exceeding 5,000, encompassing much of the commercial fleet, luxury yachts, and industrial ships.
*EEXI (Energy Efficiency Existing Ship Index)
EEXI establishes an efficiency index for each vessel based on its carbon emissions per ton of cargo transported and per nautical mile traveled. To comply with these standards, vessels need to enhance their energy performance. Solutions include:
- Engine efficiency upgrades through technological advancements.
Fuel consumption optimization.Installation of emission reduction systems like scrubbers or wind-assisted propulsion systems.
*CII (Carbon Intensity Indicator)
CII assesses a ship's annual CO2 emissions and ranks them on a scale from A to E, with "A" indicating the best performance. Vessels rated "D" for three consecutive years or "E" in any year must undergo significant modifications. These may include operational improvements or technological upgrades, such as retrofitting with more efficient engines or adopting alternative fuels like ammonia or hydrogen.
Impact on the Industry and Compliance
These regulations directly influence fleet planning and commercial operations. Non-compliance can result in penalties, port access restrictions, and loss of competitiveness. Shipowners must adapt their vessels using technological solutions that reduce emissions without compromising performance. This has led to increased investments in:
- Alternative propulsion technologies, such as wind assistance or air lubrication.
- Eco-friendly fuels with low or zero carbon content, though many are not yet widely available.
Compliance is not limited to large ships. Yachts and recreational vessels are also beginning to be affected by local and international regulations. Owners of these vessels must anticipate requirements and adopt energy-efficient solutions to avoid future issues.
