The Portuguese government will change the discount on the Special Tax on Petroleum Products (ISP) starting next week. The changes were published through an ordinance in the Official Gazette.
For diesel, the ISP discount will increase by 0.109 cents per liter. This rise represents a benefit for consumers of this fuel.
In contrast, gasoline will see its ISP discount reduced by 0.956 cents per liter. This decrease contrasts with the increase applied to diesel.
The changes were formalized today, September 11, through publication in the Official Gazette, taking effect the following week.
