Which MARPOL Annex addresses Air Pollution?

• A. Annex IV
• B. Annex I
• C. Annex II
• D. Annex VI

Answer: (D)

Air pollution from ships is addressed by the MARPOL annex that sets limits on exhaust emissions and fuel quality, aiming to reduce pollutants like sulfur oxides and nitrogen oxides from ship engines. This annex also covers measures to improve energy efficiency, including the global sulfur content limit for marine fuels and NOx emission standards that vary by engine type and date. It even includes rules to curb other harmful emissions and to promote cleaner operating practices. The other MARPOL annexes focus on different pollution types: one deals with oil pollution from ships, another with chemical cargo pollution, and another with sewage from ships, among others. So the annex dedicated to air pollution is the one that governs these exhaust-related requirements and fuels.
