According to Rob (2008), the
worldwide production of cellulosic ethanol will amount
to at least 16.5 billion gallons in 2020, if the target set in
the United States, China, Europe, Japan and Brazil are
achieved. Based on currently proposed and signed
legislation, the United States would account for over
63.9% of that market, while the EU and China would
account for 10.4% and 11.5% respectively.
