In this direction, the
European Directive on biofuels (EU-Directive 2009/28/EC, 2009)
established the goal of reaching a 10% share of renewable energy in
the transport sector in Community by 2020 and introduced mandatory
sustainability criteria which biofuels must meet under this Directive.
Biofuels must deliver greenhouse gas savings of at least 35% compared
to fossil fuels, rising to 50% in 2017 and to 60%, for biofuels from new
plants, in 2018. According to this premise and taking into account the
default values for GHG emission savings of some biofuels included in
the annex V of this Directive, new sustainable crops and process are required
to be investigated in order to achieve the European renewable
targets.
