Mandated volumes driving growth
US RFS2 … 36 Bln gals by 2022
That’s 25% of gasoline volumes
EU RED … 10% volume by 2020
“Whatever the economic picture,
it is clear that renewable fuels are here to stay and that
legislative mandates will secure
their future production.”
Robin Hunt, Infineum

“…those of us who work in and came to love this
business at traditional oil companies have to consider
that ethanol and some form of advanced renewable
fuel is no longer a temporary part of the oil business.”
Douglas Haugh, EVP & CIO, Mansfield Oil Company
