What does MARPOL Annex VI regulate and what are Emission Control Areas (ECAs)?

• A. It regulates ballast water management; ECAs are zones with ballast water exchange requirements.
• B. It regulates garbage disposal from ships; ECAs are zones with strict trash handling rules.
• C. It regulates oil pollution from ships; ECAs are zones with oil discharge limits.
• D. It regulates air pollution from ships; ECAs are zones with stricter emission limits for SOx, NOx, and particulates.

Answer: (D)

MARPOL Annex VI governs air pollution from ships and designates Emission Control Areas where emissions limits are stricter for sulfur oxides, nitrogen oxides, and particulates. It sets global limits on the sulfur content of fuel and NOx standards for new engines, and within ECAs those limits are tightened even further. Compliance in ECAs is achieved by using low-sulfur fuels, installing NOx-reducing technologies, or employing alternative fuels and propulsion methods to meet the tougher requirements. ECAs exist in regions such as the North Sea, Baltic Sea, and certain North American waters, aiming to reduce ship-related air pollution and its health and environmental impacts. The other options describe areas outside MARPOL Annex VI: ballast water management relates to ballast water rules, garbage disposal to Annex V, and oil pollution to Annex I.
