🔍 Key Concepts

• MARPOL Annex VI fuel oil sulfur limits (global cap, not Emission Control Areas) • Difference between percentage by weight (m/m) and old higher historical sulfur contents • Timeline of sulfur cap reductions under Annex VI (original limit vs later stricter limits)

💭 Think About

• Is this question asking about the original Annex VI global sulfur cap, or the much lower limit that came into force later (after 2020)? • Which of the options looks most like an earlier regulatory cap, rather than an unregulated, older "typical" high-sulfur fuel value? • How do the answer choices compare to known historical steps: very high pre‑regulation sulfur, first MARPOL cap, then later tightened caps and ECAs?

✅ Before You Answer

• Verify what the initial global sulfur cap was when MARPOL Annex VI first entered into force, before later amendments reduced it. • Confirm that the question is about fuel oil used onboard ships generally, not specifically in Emission Control Areas (ECAs). • Check that the value you choose is a maximum allowed sulfur content by mass (percent m/m) that matches the early Annex VI global cap.
