Further expansions will have uncertain, but potentially significant, effects on food prices, greenhouse gas emissions, and the U.S. farm economy. To address the market-mediated effects of expanding FOG feedstock consumption, U.S. transportation fuel program regulations are being changed in contradictory and precedent-setting ways. On the one hand, the largest U.S. state (California) is curtailing crediting for vegetable oil feedstocks. On the other hand, federal programs are restricting incentives for imported waste feedstocks like used cooking oil and tallow. These policy changes have created uncertainty about the “FOG” that will be used in biofuels production, since assessing the net effect of these changes is challenging. In this paper, I calculate the effect that these revised and proposed policies have on FOG feedstock incentives. First, I describe how federal and state transportation fuel programs incentivize FOG feedstock consumption. Second, I calculate how program adjustments change the incentives for various FOG feedstocks. I find that the changes have little net effect on U.S. soybean oil and distiller's corn oil (DCO) biomass-based diesel (BBD) incentives in California. Elsewhere in the U.S., soybean oil BBD incentives increase. In contrast, incentives for BBD produced with imported feedstocks are considerably reduced. In summary, the revisions imply that FOG feedstock incentives will be higher for DCO than for other feedstocks.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"18 2","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.70101","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146002276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To identify superior Miscanthus types, we estimated radiation use efficiency (RUE), yield and water use efficiency (WUE) from within-season measurements made over three contrasting growing seasons. Temporal variations in RUE and WUE for different genotypes varied significantly and two novel hybrids, WAT6 and WAT8, achieved the highest yields. To achieve goodness of fit to yield measurements, genotype-specific parameters for process descriptions in the model MiscanFor were adjusted for the two superior genotypes. These parameters included earlier shooting and an increased threshold of overheating. When the model was run over ten years, despite generating the highest yield values, WAT8 accumulated less biomass than WAT6 over the longer term. The response of WUE to variation in soil capillary pressure and vapour pressure deficit was examined. WUE of <i>M</i> × <i>g</i> increased with the severity of water stress then declined again.

Nitrogen recycling in <i>M. sinensis</i> is known to be efficient, but the extent of intra-specific variability and its translation into distinct functional strategies remain unknown to date. Our objective was to assess the intergenotypic variation in nitrogen uptake and recycling and their relation to biomass yield in a diploid <i>M. sinensis</i> progeny. Endogenous remobilization fluxes were calculated for 80 genotypes from seasonal nitrogen dynamics under nitrogen deficient conditions, showing substantial intergenotypic variation, ranging from 0.2 to 85 kg N ha<sup>−1</sup> in spring and 5 to 158 kg N ha<sup>−1</sup> in autumn. Recycling efficiency, defined as the remobilized nitrogen relative to maximum nitrogen quantity, did not correlate with biomass yield, indicating that nitrogen recycling was independent of plant size. Exogenous nitrogen uptake varied widely (5–241 kg N ha<sup>−1</sup>) and was strongly correlated with biomass yield (<i>r</i> = 0.72), making it the dominant factor influencing productivity, while principal component analysis highlighted the contribution of nitrogen recycling traits. Three functional groups emerged from hierarchical clustering on the principal components. The first group comprised nitrogen-acquisitive genotypes with high uptake and productivity, suitable for low-input bioenergy systems and potential ecosystem services like nitrate removal in water catchment areas. The second group followed a conservative strategy, with efficient belowground nitrogen storage and endogenous recycling, supporting resilience to environmental stress. The third group comprised nitrogen-deficient genotypes with low uptake, remobilization, and productivity. These findings demonstrate that substantial variation in nitrogen economy traits defined distinct functional groups in <i>M. sinensis</i>, providing a framework for breeding ideotypes that sustain biomass under nitrogen-limited conditions through enhanced uptake or remobilization, while delivering ecosystem services through contrasting remobilization strategies that can support nutrient retention, soil nitrogen conservation, and water quality regulation.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"18 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.70096","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145824722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long, FRS (Steve) was born in London in 1950. His passion for plant science was the result of an inspiring schoolteacher, Ms. Muriel Hoskins, and recognition that new science and biotechnology were needed to address the famines being experienced by the Global South in the 1960s. As a result, he studied agricultural botany at Reading University, graduating with a B.Sc. in 1972. He then went on to earn a Ph.D. from Leeds University in 1976 for research that revealed that plants with C4 photosynthesis were naturally present in the UK and not limited to tropical regions. He added to this formal education while visiting Kenya and India as a teacher for the United Nations Environment Programme (UNEP) during the 1970s and 1980s. These formative experiences underpinned a research agenda that Steve would pursue with remarkable success for the rest of his career, i.e., understanding and engineering photosynthesis to improve agricultural productivity, resilience and sustainability in the face of global environmental change. His landmark contributions included work on C4 photosynthesis, photosynthetic responses to both heat and cold, photosynthetic and productivity responses to atmospheric changes, photosynthetic productivity of biomass crops, cross-scale modelling of photosynthesis and plant function, and engineering of photosynthesis to improve crop yield. Along the way, Steve consistently kept pace with the latest technologies, finding ways to leverage them to accelerate progress.

The latter, including applications in the construction, textile, chemical, or agricultural sector, is becoming increasingly relevant today. In general, it is hypothesised that biobased products are advantageous in terms of their greenhouse gas (GHG) performance when compared to conventional—in particular fossil—alternatives. To investigate this, the life cycle assessment methodology is typically applied. However, assessments are subject to uncertainty and variability due to assumptions and methodological choices. Given the increasing interest in miscanthus-derived material applications, this study aims to draw more general conclusions about their GHG performance and relative mitigation potential. This should support a better understanding of their contribution to climate change mitigation objectives and guide the selection of promising products or product groups. A systematic review of peer-reviewed literature was conducted. In total, 20 studies reporting on 188 comparisons of the GHG performance of miscanthus-derived and alternative products were assessed. Most comparisons indicated potential GHG mitigation through miscanthus-derived products, with the majority ranging between 20% and 100% savings. Key parameters defining the relative performance include the selection of the reference product, consideration of soil carbon changes, changes in product and process design, as well as the incorporation of indirect Land Use Change (iLUC) impacts. Overall, we conclude that miscanthus-derived material applications have the potential to contribute to GHG emission mitigation if iLUC effects are minimised. Given the limited availability of agricultural land, miscanthus-derived products with high absolute GHG mitigation potential per unit of biomass used and long product lifetime are preferable.
