The Carbon Tax on Businesses document (Failte Ireland, 2010) gives information about expected cost increases because of taxes on carbon emissions. The carbon tax at EUR 15 per tonne came into effect on 10 December 2009 in respect of petrol and auto diesel, and from 1 May 2010 has also been applied to kerosene, marked gas oil {i.e. 'green diesel' or 'agricultural diesel’), liquefied petroleum gas (LPG), fuel oil and natural gas. The application of the tax to coal and commercial peat is subject to a Commencement Order.
