Abstract

To achieve carbon neutrality, the development and application of low-carbon, zero-carbon, and negative-carbon technologies are crucial for transforming energy and industrial structures. Prospective Life Cycle Assessment (PLCA) serves as a vital tool in this transformation by providing a forward-looking framework for evaluating the future environmental impacts of emerging technologies. PLCA not only considers the scaling of technologies but also focuses on resource efficiency and energy system optimization. However, current PLCA frameworks often face challenges related to data limitations and inconsistencies in evaluation models, which can lead to uncertainties in environmental impact assessments. This paper proposes a robust and scientifically PLCA framework to reduce modeling uncertainties and support the carbon neutrality goal.

Based on the summary of the current research and application of PLCA, focusing on its role in assessing low-carbon, zero-carbon, and negative-carbon technologies in key sectors such as industry, transportation, construction, and agriculture, the paper identifies critical issues that PLCA must address to support the future development of these technologies. Through this enhanced PLCA framework, the paper aims to offer methodological support for decision-making in technology selection and energy optimization, providing policymakers with a clear path to advance carbon-neutral strategies while ensuring environmental sustainability and economic efficiency.

实现碳中和目标的前瞻性生命周期评估：框架应用与挑战

为了实现碳中和，开发和应用低碳、零碳和负碳技术对于能源和工业结构的转型至关重要。前瞻性生命周期评估（PLCA）为评估新兴技术对未来环境的影响提供了一个前瞻性框架，是实现这一转变的重要工具。前瞻性生命周期评估不仅考虑技术的规模，还关注资源效率和能源系统优化。然而，当前的 PLCA 框架经常面临数据限制和评估模型不一致等挑战，这可能导致环境影响评估的不确定性。本文在总结当前 PLCA 研究和应用的基础上，重点关注 PLCA 在评估工业、交通、建筑和农业等关键领域的低碳、零碳和负碳技术中的作用，提出了 PLCA 必须解决的关键问题，以支持这些技术的未来发展。通过这一强化的 PLCA 框架，本文旨在为技术选择和能源优化决策提供方法论支持，为政策制定者提供一条清晰的路径，以推进碳中和战略，同时确保环境可持续性和经济效益。
