1 Introduction

Biofuel has been recognized as a promising solution to sustainable and low-
carbon transport, because it can be produced from various types of biomass
to substitute the petroleum-derived fuel and reduce emissions from transport
sector (Hao et al., 2018). Biofuel is one of the most promising renewable
energy carriers, and it can be produced from various feedstocks such as bio-
mass, algal, and some other nonstaple food crops (Liang et al., 2016). How-
ever, there are also some challenges for promoting the development of
biofuels including the relatively higher production, the negative impacts
on food security, and competition with some other renewable energy
resources (Ren et al., 2015a). Meanwhile, there are also some emissions
in the whole life cycle of biofuels, because there is also some consumption
for cropping, transportation of biomass resources, biofuel production, trans-
portation of biofuels, and so on (Ren et al., 2014). Therefore the
