联合国于1987年将可持续发展定义为既满足当代人的需求，又不损害后代人满足自身需求的能力的发展，这是本文的核心概念。这项工作承认可持续性的三个方面，即，经济、社会和环境，但它的重点是最后一个。数字双胞胎（DT）通常被描述为一个物理实体与一个虚拟的对手，以及数据，两者之间的连接，这意味着连接器和块的存在，以实现高效和有效的数据通信。本文提供了Meta系统文献综述（SLR）（即，关于基于DT的系统的可持续性要求。还选择了许多关于DT主题的论文，因为它们引用了分析的SLR，并被认为与本研究的目的相关。通过对29篇论文的选择和分析，发现了一些局限性和挑战：对可感知的信通技术的好处没有得到明确的理解;对整个产品生命周期或信通技术生命周期的信通技术没有进行充分的研究;尚不清楚信通技术如何有助于降低成本或支持决策;信通技术的技术实施必须得到改进，并更好地结合物联网; DT的保真度水平没有完全根据其参数、准确性和抽象级别进行评估;存储在DT中的数据的所有权应该得到更好的理解。此外，从我们的研究中，不可能找到一篇仅从环境可持续性角度讨论DT的论文。
Sustainable development was defined by the UN in 1987 as development that meets the needs of the present without compromising the ability of future generations to meet their own needs, and this is a core concept in this paper. This work acknowledges the three dimensions of sustainability, i.e., economic, social, and environmental, but its focus is on this last one. A digital twin (DT) is frequently described as a physical entity with a virtual counterpart, and the data, connections between the two, implying the existence of connectors and blocks for efficient and effective data communication. This paper provides a meta systematic literature review (SLR) (i.e., an SLR of SLRs) regarding the sustainability requirements of DT-based systems. Numerous papers on the subject of DT were also selected because they cited the analyzed SLRs and were considered relevant to the purposes of this research. From the selection and analysis of 29 papers, several limitations and challenges were identified: the perceived benefits of DTs are not clearly understood; DTs across the product life cycle or the DT life cycle are not sufficiently studied; it is not clear how DTs can contribute to reducing costs or supporting decision-making; technical implementation of DTs must be improved and better integrated in the context of the IoT; the level of fidelity of DTs is not entirely evaluated in terms of their parameters, accuracy, and level of abstraction; and the ownership of data stored within DTs should be better understood. Furthermore, from our research, it was not possible to find a paper discussing DTs only in regard to environmental sustainability.
