Why is Libyan crude oil valued by countries with strict pollution standards?

Libyan crude oil is highly valued by countries with strict environmental regulations because it is low in sulfur content.1

In the petroleum industry, sulfur compounds are considered undesirable impurities. When present in fuels, they can cause engine corrosion, reduce the effectiveness of additives, and complicate the operation of exhaust-treatment systems. Furthermore, because sulfurous emissions are subject to stringent restrictions in many developed areas, the low-sulfur nature of Libyan oil makes it a preferred choice, as it results in less pollution and less equipment corrosion compared to most other crude oils.21
