Biofuels Obligation Scheme

The BOS Scheme places an obligation on suppliers of mineral oil to ensure that 11.111% (by volume) of the motor fuel (generally gasoline and motor diesel) they place on the market in Ireland is produced from renewable sources, e.g. ethanol and biodiesel. The obligation was increased from the 1st January, 2019. It was previously 8.695%.

Under the terms of the National Oil Reserves Agency Act 2007 (Returns and Biofuel Levy) Regulations 2010, a Biofuel Levy of 2.00 cent per litre is payable on the sales of all Biofuels into the market with effect from 1st July 2010.


Article 3 of the Renewable Energy Directive (1) sets out mandatory national overall targets and measures for the use of energy from renewable sources for all EU Member States. Ireland’s target for the share of its gross final consumption of energy to come from renewable sources, by 2020, is 16%.

Although Member States may set individual targets for heat and electricity, item 4 of Article 3 places the following obligation on all Member States.

Each Member State shall ensure that the share of energy from renewable sources in all forms of transport in 2020 is at least 10 % of the final consumption of energy in transport in that Member State.

It is in the context of this obligation that Ireland has implemented the Biofuel Obligation Scheme (BOS) which was given effect in law by the Energy (Biofuel Obligation and Miscellaneous Provisions) Act 2010 (2). The Scheme is one aspect of a twin approach in meeting the EU target for the use of renewable energy in transport; the second is to encourage the accelerated development and usage of electric vehicles, for which the target is 10% of vehicles by 2020.

Under this legislation, The National Oil Reserves Agency (NORA) is the body charged with administering the BOS. In June 2010, following an open tendering process, a consortium of Byrne Ó Cléirigh and LHM-Casey McGrath (BÓC-CMG) was appointed to assist NORA to implement and administer the BOS.
