The purpose of this document is to carry out a critical review of the existing literature by specifically addressing the following: (i) the integration of life cycle assessment and life cycle cost assessment from the perspective of research topics, category and scope of study, authors, institutions, countries, and journals working on or publishing related studies, and (ii) the main aids, challenges, opportunities, methodological difficulties, and current research efforts on the integrated approach of both tools. A systematic review was conducted to identify studies with an integrated use of life cycle assessment and life cycle cost in several areas. An analysis of the main aspects of the studies identified, such as bibliographic reference, year of publication, institution where the research was conducted, country, area of application, category of study, journal of publication, impact factor, and number of citations was conducted. After a search in the Science Direct, Scopus, and Web of Science databases, 349 documents were identified. After a series of filters (excluding gray literature, reading titles and keywords, reading abstracts, and reading full-texts), which helped ruling out articles that did not contribute to investigating the integration of life cycle assessment and life cycle cost assessment, 90 documents were selected for a detailed analysis. The leading role of the USA and European countries in this issue should be highlighted. The integration of life cycle assessment and life cycle cost seems to be most advanced in the areas of building design and civil construction. Different strategies for the integration of the methodologies are also found, being mathematical modelling and programming for optimization, and multi-criteria decision-making the most recurrent methods. Moreover, there seems to be more challenges than opportunities in said integration. The challenges include the monetization of environmental impacts, higher volatility of economic data compared to environmental data, and differences in environmental and economic background data. These challenges can be turned into opportunities in the development of more comprehensive methodological approaches. Challenges (e.g., time-, resource- and knowledge-intensive, different scopes) and opportunities (e.g., common system boundaries, benefitting from LCA structure to conduct LCC) for the integration of life cycle assessment and life cycle cost were identified. This combined approach allows projects, products, and services to reduce environmental and economic impacts, which can be quantified and compared through improved assessment of potential trade-offs.

整合生命周期评估和生命周期成本：环境经济研究回顾

本文件的目的是通过具体解决以下问题对现有文献进行批判性审查：(i) 从研究主题、研究类别和范围、作者的角度，生命周期评估和生命周期成本评估的整合、从事或发表相关研究的机构、国家和期刊，以及 (ii) 主要帮助、挑战、机遇、方法上的困难，以及目前关于这两种工具的综合方法的研究工作。进行了系统评价，以确定在多个领域综合使用生命周期评估和生命周期成本的研究。对确定的研究主要方面的分析，例如参考书目、出版年份、进行研究的机构、国家、应用领域、进行了研究类别、出版期刊、影响因子和引用次数。在 Science Direct、Scopus 和 Web of Science 数据库中进行搜索后，确定了 349 篇文档。经过一系列过滤（排除灰色文献、阅读标题和关键词、阅读摘要、阅读全文），排除了对调查生命周期评估和生命周期成本评估的整合没有贡献的文章，90篇文献被选中进行详细分析。美国和欧洲国家在这个问题上的主导作用应该得到强调。生命周期评估和生命周期成本的整合在建筑设计和土木建筑领域似乎是最先进的。还发现了整合这些方法的不同策略，用于优化的数学建模和编程以及多标准决策是最常见的方法。此外，在上述整合中，似乎挑战多于机遇。挑战包括环境影响的货币化、与环境数据相比经济数据的更高波动性以及环境和经济背景数据的差异。这些挑战可以转化为开发更全面的方法论方法的机会。确定了整合生命周期评估和生命周期成本的挑战（例如，时间、资源和知识密集型，不同范围）和机会（例如，共同系统边界，受益于 LCA 结构进行 LCC）。这种组合方法允许项目、产品、
