Addendum to “Gasoline ether oxygenate occurrence in Europe, and a review of their fate and transport characteristics in the environment”

Report no. 3/18: Ether oxygenates are added to certain gasoline (petrol) formulations to improve combustion efficiency and to increase the octane rating. In 2012 Concawe published the findings of research to support effective environmental management practices for gasoline ether oxygenates (GEO) in Concawe Report 4/12 "Gasoline ether oxygenate occurrence in Europe, and a review of their fate and transport characteristics in the environment" (Concawe, 2012).

This addendum report provides an updated appraisal of trends in 1999-2015 fuel GEO content as well as trends in the ethanol (EtOH) content of gasoline from 2010-2015.
