Fuels make up a large share of global energy demand (*66%). The development
of CO2-neutral fuels is one of the most urgent challenges facing in our society, to
reduce gaseous emissions and their consequential climatic changes, greenhouse
and global warming effects. Biofuel production is expected to offer new opportunities
to diversify income and fuel supply sources and can help to reduce the
adverse effects of the frequent oil supply crisis, as well as developing long-term
replacement of fossil fuels, helping non-fossil–fuel-producing countries to reduce
energy dependence. This will in turn promote employment in rural areas, reduce
greenhouse gas (GHG) emissions, boost the decarburization of transportation
fuels, increase the security of energy supply and promote environmental
sustainability.
