Energy use for transport comprises a significant and ever increasing proportion of energy use in Ireland. From 1990 to 2005, the transport sector?s share of the total final energy consumption increased from 27.8% to over 40%. Final energy use in the transport sector has grown by 151% (6.3% per annum on average) between 1990 and 2005. The transport sector is also the sector most dependant on imported fossil fuels with resultant impacts on security of fuel supplies and exposure to oil price fluctuations. CO2 emissions from the transport sector in 2005 were 15 270 kilotonnes, representing over 33% of total energy-related CO2 emissions. Using biofuels reduces dependency on imported oil and the environmental impacts of transport energy use, in particular greenhouse gas emissions. Using biofuels also creates national and local economic benefits by creating an indigenous biofuels industry.

The use of ethanol?diesel blends in the transport fleet would provide another alternative biofuel for use in centrally fuelled diesel engines which would complement the existing alternative fuels: PPO, biodiesel and EN 590 biodiesel blends. Like other biofuels, it offers the potential to reduce CO2 emissions from transport and reduce dependency on imported fossil fuels while fostering an indigenous biofuels industry. eDiesel offers the benefit of easy use in existing engines without modification, and can directly replace (i.e. is fungible) diesel, allowing operators to fill eDiesel trucks with diesel from forecourts. An important differentiation factor between eDiesel and other biofuels is the reduction in smoke, particulate and NOx emissions from engines that is achieved due to the oxygenation effect of the fuel. This is an important benefit in terms of air quality and national emission inventories, but very few of the fleet operators surveyed viewed this as a significant benefit.

Description of Geographical Characteristics of This Project or Dataset
The exact locations of the 81 companies, representing 71 separate organisations surveyed to determine the extent of centrally fuelled captive fleets and the potential market for eDiesel is private. However these companies are currently operating on the island of Ireland. Responses were received, and phone interviews conducted with 33 of the organisations surveyed. The highest response rate was from local authorities with the lowest being in general fleet operators and logistics/haulier companies.
