New scientific study led by Olufemi Oni, a renowned chemical and environmental engineer, is shedding light on the environmental impact of sulphur dioxide (SO₂) emissions and offering practical solutions for cleaner fuel management in developed countries. The study provides actionable insights that aim to support global energy sustainability and air pollution control efforts.
Published in the Journal of Energy, Environmental and Chemical Engineering in 2024, Olufemi’s research—titled “Determination of Sulphur Dioxide Air Emission of Refined Petroleum Products by Emission Factor Approach for Air Pollution Control”—focuses on three fuel products: Premium Motor Spirit (PMS), Automotive Gas Oil (AGO), and Dual-Purpose Kerosene (DPK).
Using advanced analytical techniques and a robust emission factor approach, Oni developed a process to accurately quantify sulphur content in refined petroleum products and estimate the resulting SO₂ emissions. This innovative approach includes a seven-year emission forecast, designed to help oil and gas companies evaluate the environmental footprint of their products before distribution or export.
A major finding from the study revealed that diesel fuel (AGO) contains the highest sulphur levels among the three products studied—an insight that underscores the urgent need for data-driven regulatory controls and cleaner refining practices in diesel production. “This research is intended to empower policymakers, refineries, and environmental agencies with the data they need to make informed decisions,” said Oni. “By aligning industry practices with environmental standards, we can protect public health while ensuring long-term energy sustainability.”
The study not only calls for rigorous emission monitoring but also reinforces the integration of science-based strategies into national and international environmental policy. It supports global initiatives such as the United Nations Sustainable Development Goals (SDGs), particularly those addressing clean energy
(Goal 7), climate action (Goal 13), and good health and well-being (Goal 3).
