The construction sector has significant environmental impacts. It contributes substantially to the world’s energy demand, global emissions, and extensive use of minerals. To address these challenges, it is crucial to develop and implement strategies that reduce the environmental footprint of construction supply chains. Among common construction materials, concrete stands out due to its substantial impact. This study investigates decarbonisation and circularity strategies within the concrete supply chain from the perspective of cleaner processes. The study encompasses a range of scenarios, including a business-as-usual scenario, as well as scenarios incorporating cleaner electricity, transportation, and thermal energy sources. Following the guidelines of Life Cycle Assessment, the methodology is applied across various stages of the concrete supply chain, spanning from cement and concrete production to the construction of a building. Three different functional units are used for this assessment, namely the production of 1 ton of cement, 1 m3 of concrete, and the construction of 1 m2 of a reinforced concrete building. The work presented in this paper is part of the efforts of the UKRI and EPSRC-funded Interdisciplinary Circular Economy Centre for Mineral-based Construction Materials (ICEC-MCM). The aim of the centre is to develop the multidisciplinary understanding that will serve as the basis to support the transition to a sustainable Circular Economy, particularly for the case of the built environment. Apart from academics, the centre is supported by a network of more than 60 partners from different sectors of the construction industry, government agencies, and non-governmental organisations (NGOs).
