Biofuels are being promoted as a low-carbon alternative to fossil fuels they could help reduce greenhouse gas (GHG) emissions and the related climate change impact from transport. However, there also concerns that their wider deployment lead unintended environmental consequences. Numerous life cycle assessment (LCA) studies have considered other impacts of biofuels. findings often conflicting, with wide variation in estimates. Thus, aim this paper is review analyse latest available evidence provide greater clarity understanding different liquid It evident outcomes LCA highly situational dependent on many factors, including type feedstock, production routes, data variations methodological choices. Despite this, existing suggests that, if no land-use (LUC) involved, first-generation biofuels can—on average—have lower GHG than fuels, but reductions for most feedstocks insufficient meet savings required by EU Renewable Energy Directive (RED). second-generation have, general, potential emissions, provided LUC. Third-generation do not represent feasible option at present state development higher those fuels. As discussed paper, several show achieved expense impacts, such acidification, eutrophication, water footprint biodiversity loss.

Abstract Lignocellulose is the most abundant biomass on Earth, with an estimated 181.5 billion tonnes produced annually. Of 8.2 that are currently used, about 7 from dedicated agricultural, grass and forest land another 1.2 stem agricultural residues. Economic environmentally efficient pathways for production utilization of lignocellulose chemical products energy needed to expand bioeconomy. This opinion paper arose research network “Lignocellulose as new resource platform novel materials products” funded by German federal state Baden‐Württemberg summarizes original presented in this special issue. It first discusses how supply lignocellulosic can be organized sustainably suggests perennial crops (PBC) likely play important role future regional European biorefineries. Dedicated PBC has advantage delivering reliable quantity quality. The tailoring quality through crop breeding management support integration value chains. Two biorefinery concepts using then compared discussed: syngas biorefinery. Syngas biorefineries less sensitive qualities technically relatively advanced, but require high investments large‐scale facilities economically feasible. Lignocellulosic multiple processing steps separate recalcitrant lignin cellulose hemicellulose convert intermediates into valuable products. refining processes high‐quality fractions still need further developed. A concept a modular could flexibly adapted range feedstock combining appropriate technologies either at same location or decentralized form.

The undeniable environmental ramifications of continued dependence on oil-derived jet fuel have spurred international efforts in the aviation sector towards alternative solutions. Due to limited options for decarbonisation, successful implementation bio-aviation is crucial contributing roster greenhouse gas emissions mitigation strategies sector. Since fleet replacement with low-carbon technologies may not be a feasible option, due long lifetime and significant capital cost aircraft, 'drop-in' alternatives, which can used engines existing aircraft seamless transition, required.

Abstract Natural revegetation, afforestation, and lignocellulosic crops for bioenergy, possibly coupled with a developing technology like carbon capture storage, are the most common land-based climate change mitigation options. However, they can compete land threaten food security or nature conservation. Using abandoned cropland their deployment minimize these risks, but associated potentials unclear. Here, we compare alternative options by integrating historical future (up to 2050) site-specific biomass yields life-cycle emissions. Considering natural revegetation in biodiversity priority areas different measures remaining achieve potential of 0.8–4.0 GtCO 2 -equivalents yr −1 (2–11% 2021 global CO emissions). Afforestation generally provides larger benefits than bioenergy storage delivers highest locations. Overall, results offer refined estimates from highlight opportunities context-specific measures.

Biofuels represent source energy, but their production raised concerns regarding possible impacts on food security. Indeed, current biofuel primarily relies crops and arable lands. That is in conflict with need produce more increasing world population. To overcome this incongruence, it proposed cultivate second-generation marginal lands, since option could bring benefits terms security sustainability. Based scientific literature, we addressed following critical points: (i) whether land worldwide can be considered reasonable lands production; (ii) evaluate sustainability respect unintended negative consequences crop cultivation such indirect use change, social insecurity loss biodiversity.
