Reference Answer

**(a) What are the sulphur limits for fuel in use under MARPOL?**
Under MARPOL Annex VI, the International Convention for the Prevention of Pollution from Ships, stringent sulphur limits for fuel oil in use are imposed globally and within designated Emission Control Areas (ECAs). These limits are critical for reducing harmful sulphur oxide (SOx) emissions, which contribute to acid rain, respiratory illnesses, and particulate matter.
* **Global Sulphur Cap:**
* Since **1 January 2020**, the global limit for the sulphur content of fuel oil used on board ships operating outside designated ECAs has been **0.50% m/m** (mass by mass).
