Issues related to fuels are governed in the European Union by Directive 98/70/EC of the European Parliament and of the Council of 13 October 1998 relating to the quality of petrol and  diesel fuel, and amending Council Directive 93/12/EEC, whose last substantial amendment was effected by Directive of the European Parliament and of the Council 2009/30/EC of 23 April 2009 amending Directive 98/70/EC as regards the specification of petrol, diesel and gas-oil and introducing a mechanism to monitor and reduce greenhouse gas emissions and amending Council Directive 1999/32/EC as regards the specification of fuel used by inland waterway vessels and repealing Directive 93/12/EEC.

Recent amendments to the directive have mainly introduced changes to fuel specification, such as higher contents of fuel biocomponents in diesel fuel which were  increased to 7% and to 10% for petrol.

The Directive also regulates such issues as reduction of greenhouse gas emissions across the entire fuel life cycle and sustainable development as regards raw materials used in production of biocomponents.
These directives were implemented into the Polish legislative framework by act of 25 August 2006 on the monitoring and the auditing scheme for the quality of fuel (Journal of Laws from 2006 No 169, pos. 1200, as amended).
