Global Trends in Sulphur Reduction

This document summarizes evidence and policy pathways for cutting transport-related air pollution by lowering fuel sulphur and aligning fuels with vehicle emission standards. It links high particulate matter burdens in African cities to fuel quality and shows that sulphur content is proportional to PM and SO₂ emissions, affecting old and new fleets alike. t promotes a systems approach—low-sulphur fuels paired with Euro IV–VI standards—and cites projections that global adoption of Euro 6/VI with 10 ppm sulphur by 2030 would cut vehicle PM about 90% and avert over 210,000 early deaths, saving 25 million life-years.
