生命周期评估（LCA）在通知可持续和循环生物经济的发展的作用进行了讨论。我们分析了在使用生命周期评估方面仍然存在的关键挑战，并提出了解决未来发展挑战所需的改进措施。生物基系统往往是技术和做法的复杂组合，在地理上分散在很远的地方，具有各种各样和不确定的指标和影响。最近的研究提供了方法上的建议，如何可以改善生命周期评估的可持续性的生物为基础的系统，新的重点是新兴的系统，帮助确定环境和社会的机会之前，大规模的研发投资。然而，实现规模经济和提高转化效率，同时保持广泛的可持续性指标的兼容性和公众的接受程度，仍然是生物经济面临的主要挑战。LCA可以提供信息，但本身不能解决这个复杂的可持续性问题。未来旨在促进生物经济和支持战略价值链的政策干预措施将受益于LCA的系统使用。然而，LCA社区需要开发所需的机制和工具，以达成协议并协调标准和激励措施，以支持成功的生物基过渡。系统的利益相关者参与和使用多学科分析结合LCA是紧急LCA方法的重要组成部分。这篇文章是“新兴技术的生物衍生和生物启发的可持续先进材料（第1部分）”主题的一部分。
The role of life cycle assessment (LCA) in informing the development of a sustainable and circular bioeconomy is discussed. We analyse the critical challenges remaining in using LCA and propose improvements needed to resolve future development challenges. Biobased systems are often complex combinations of technologies and practices that are geographically dispersed over long distances and with heterogeneous and uncertain sets of indicators and impacts. Recent studies have provided methodological suggestions on how LCA can be improved for evaluating the sustainability of biobased systems with a new focus on emerging systems, helping to identify environmental and social opportunities prior to large R&D investments. However, accessing economies of scale and improved conversion efficiencies while maintaining compatibility across broad ranges of sustainability indicators and public acceptability remain key challenges for the bioeconomy. LCA can inform, but not by itself resolve this complex dimension of sustainability. Future policy interventions that aim to promote the bioeconomy and support strategic value chains will benefit from the systematic use of LCA. However, the LCA community needs to develop the mechanisms and tools needed to generate agreement and coordinate the standards and incentives that will underpin a successful biobased transition. Systematic stakeholder engagement and the use of multidisciplinary analysis in combination with LCA are essential components of emergent LCA methods. This article is part of the theme issue ‘Bio-derived and bioinspired sustainable advanced materials for emerging technologies (part 1)’.
