Owing to its versatility, biomass can be used for a range of CO mitigation and removal options. The recent adoption of end-of-century temperature targets at the global scale, along with mid-century economy-wide net zero emission targets in Europe, has boosted demand forecasts for this valuable resource. Given the limited nature of sustainable biomass supply, it is important to understand most efficient uses of biomass, both in terms of avoided CO emissions (., substituted energy and economic services) and CO removal. Here, we quantify the mitigation and removal potential of key bio-based CO removal pathways for the transport, power, construction, and iron and steel sectors in Europe. By combining the carbon balance of these pathways with their economics, the optimal use of biomass in terms of CO avoidance and removal costs is quantified, and how these evolve with the decarbonization of the European energy system is discussed.
由于其多功能性，生物质可用于一系列二氧化碳减排和去除方案。近期全球范围内采用了本世纪末的温度目标，以及欧洲本世纪中叶全经济范围的净零排放目标，这推动了对这种宝贵资源的需求预测。鉴于可持续生物质供应的有限性，了解生物质在避免二氧化碳排放（如替代能源和经济服务）和去除二氧化碳方面的最有效利用非常重要。在此，我们对欧洲交通、电力、建筑以及钢铁行业关键的生物基二氧化碳去除途径的减排和去除潜力进行了量化。通过将这些途径的碳平衡与其经济情况相结合，量化了生物质在避免二氧化碳排放和去除成本方面的最优利用，并讨论了这些情况如何随着欧洲能源系统的脱碳而演变。
