Abstract
• Green infrastructure has the potential to benefit 32 SDG targets. • Maximising ecosystem services while minimising costs is essential for green infrastructure planning. • Data Envelopment Analysis (DEA) can be a useful approach for evaluating environmental efficiency. • Integrating DEA with machine learning is a promising approach for measuring environmental efficiency. Green infrastructure (GI) planning is a strategy to cope with climate change and can potentially contribute directly or indirectly to all Sustainable Development Goals (SDGs). Given resource limitations, integrating the concept of environmental efficiency into GI planning is essential for enhancing cost-effectiveness. However, there is limited research on the environmental efficiency of GI, as well as its specific contributions to SDG targets. This study aims to explore how the planning of GI can help achieve the SDGs by applying an environmental efficiency perspective and identifying existing research gaps. A bibliographic analysis of 427 scientific articles is used to identify current trends in the field. The key findings highlight that a) GI can contribute directly to SDG 2, 3, 6, 10, 11, 13, 14, and 15; b) GI has the potential to benefit 32 SDG targets; c) the Data Envelopment Analysis (DEA) method may be suitable for assessing environmental efficiency; and d) integrating machine learning algorithms with DEA can enhance the reliability of environmental efficiency measurement. In summary, environmental efficiency plays a vital role in planning GI and helps decision-makers realise the SDG targets.
