### (a) What are the sulphur limits for fuel in use under MARPOL?
MARPOL Annex VI sets stringent regulations for the prevention of air pollution from ships, primarily targeting sulphur oxide (SOx) emissions. These regulations specify limits on the sulphur content of fuel oil used onboard ships, differentiating between global limits and more restrictive limits within designated Emission Control Areas (ECAs).
