As a residual product, its combustion releases significant quantities of carbon dioxide (CO2), contributing to greenhouse gas emissions. Often referred to as bunker C fuel oil or residual fuel oil, this substance is the bottom fraction remaining after the distillation of crude oil, making it highly viscous and energy-dense.

Furthermore, the formation of asphaltenes—hard, brittle particles—in stored fuel can lead to filter blockages and engine failures, necessitating constant monitoring and the use of dispersant additives to maintain fuel stability. Environmental Impact and Carbon Intensity Beyond sulfur, the heavy bunker oil sector faces intense scrutiny regarding its carbon footprint.
Its low cost per unit of energy has historically made it the fuel of choice for the international shipping industry, underpinning the complex supply chains that move consumer goods across continents. Many vessels now rely on Very Low Sulfur Fuel Oil (VLSFO), while others have installed exhaust gas cleaning systems, known as scrubbers, to continue using the higher-sulfur heavy bunker oil while remaining compliant with emissions standards.

5%, in stark contrast to the low-sulfur diesel used in road vehicles. The industry is under pressure to adopt alternative fuels, such as liquefied natural gas (LNG), biofuels, and eventually hydrogen or ammonia.
