Carbon Costs of IMO 2020?

CO2 intensity of oil refineries could rise by 20% due to IMO 2020 regulations, according to the estimates in this data-file, if a refinery chooses to convert all its high-sulphur fuel oil into low-sulphur diesel.

The drivers are an extra stage of cracking, plus higher-temperature hydrocracking and hydrotreating, which will also have the knock-on consequence of increasing hydrogen demands.

Higher CO2 intensity conflicts with the industry’s aim of lowering its net emissions, and a 20% increase would effectively undo 30-years of prior efficiency gains in the refining industry.
