Bioenergy with carbon capture and storage (BECCS) is a key greenhouse gas removal option, proposed by many integrated assessment model outcomes to help achieve negative emissions in the coming century to offset residual emissions in "difficult-to-abate" sectors - in order to meet net zero emissions targets to which Scotland and the UK are committed (Smith et al., 2016). One of the critical challenges to delivering BECCS relates to the sustainability of the biomass feedstock and the supply chains for that feedstock. This project addresses exactly this issue. What is the sustainability profile of different bioenergy feedstock supply chains - and how can they be selected and optimise to not only do least harm to ecosystem services and the UN sustainable development goals (SDGs; minimise trade-offs), but how could they contribute positively (maximise co-benefits and synergies)? Building on the work of Smith et al. (2019) and Albanito et al., (2019), the work in this project will involve using data from Drax, Europe's largest biomass-fuel power station, to examine impacts on ecosystem services and the UN SDGs of various stages of the biomass supply chain - and to quantify likely impacts through modelling of actual and alternative supply chains. The findings will also be used to help inform and refine biomass supply sustainability criteria for the industry, to help capture the benefits of BECCS while also delivering the best environmental and societal outcomes. The student will be trained in quantitative data analysis, statistics, life cycle assessment and mathematical modelling.Albanito, F. et al. 2019.

碳捕获与封存生物能源（BECCS）是一种关键的温室气体减排方案，由许多综合评估模型结果提出，有助于在下个世纪实现负排放，抵消“难以减排”行业的残余排放——从而实现苏格兰和英国承诺的净零排放目标（Smith 等，2016）。提供 BECCS 的关键挑战之一涉及生物质原料和该原料供应链的可持续性。这个项目正是解决这个问题。不同生物能源原料供应链的可持续性概况是什么？如何选择和优化它们，不仅可以最大限度地减少对生态系统服务和联合国可持续发展目标（SDG；最大限度地权衡）的损害，而且可以如何做出积极贡献（最大化共同利益和协同效应）？以史密斯等人的工作为基础。 (2019) 和 Albanito 等人 (2019) 中，该项目的工作将涉及使用欧洲最大的生物质燃料发电站 Drax 的数据来研究生物质供应各个阶段对生态系统服务和联合国可持续发展目标的影响链 - 并通过对实际和替代供应链进行建模来量化可能的影响。研究结果还将用于帮助制定和完善该行业生物质供应的可持续性标准，以帮助获得 BECCS 的优势，同时提供最佳的环境和社会成果。学生将接受定量数据分析、统计、生命周期评估和数学建模方面的培训。Albanito, F. 等人。 2019。英国国内生物质生产集中式与分布式 BECCS 的缓解潜力和环境影响。全球变化生物学生物能源（早期在线）。Smith, P. 等人。 2016。二氧化碳负排放的生物物理和经济限制。 《自然·气候变化》6, 42-50。Smith, P. 等人。 2019。陆基温室气体清除方案对生态系统服务和联合国可持续发展目标的影响。环境与资源年度回顾 44, 4.1-4.32。 doi: 10.1146/annurev-environ-101718-033129。碳捕获和储存生物能源 (BECCS) 是一种关键的温室气体清除方案，旨在帮助在下个世纪实现负排放，以抵消“难以减少的地区”的残余排放“部门 - 为了实现苏格兰和英国承诺的净零排放目标。提供 BECCS 的关键挑战之一涉及生物质原料和该原料供应链的可持续性。这个项目正是解决这个问题。不同生物能源原料供应链的可持续性概况是什么？如何选择和优化它们，不仅对生态系统服务和联合国可持续发展目标（最小化权衡）造成损害最小，而且如何做出积极贡献（最大化共同利益和协同作用）？生物科学是解决这些问题的核心 - 因此该项目完全符合 BBSRC 战略重点的职权范围：可再生资源和清洁增长的生物科学。
