Inequalities in the production and use of cement and concrete, and their consequences for decarbonisation and sustainable development

Concrete is vital for constructing infrastructure and housing, and cement is the key binding material within concrete. Concrete is an enabler of development, as concrete structures are key to delivering societal services in many sectors. Much recent research on cement and concrete has focussed on technical solutions to decarbonisation; however, there is a knowledge gap around how cement and concrete intersect with other facets of sustainable development. This study explores the intersection of cement and concrete with inequalities, both through their production as commodities and through their use in built assets. An exploratory analysis of this issue was carried out, comprising an evaluation of industry associations' conceptions of sustainable development and inequalities, an analysis of underlying power dynamics for several inequality issues using Lukes' three dimensional framework of power, and a reflection on how certain inequalities may pose risks to achieving decarbonisation and sustainable development aims. Our study shows that industry associations' narratives around sustainable development generally lack a detailed vision for addressing inequalities, in comparison to their focus on decarbonisation. We find that inequalities are a systemic issue for cement and concrete, spanning intra- and inter-national scales, and all three dimensions of power. These findings highlight that several inequalities are consequential from structural, underlying inequalities, whilst other inequalities are specific to the sectors themselves. The cement and concrete sectors are recommended to develop their conception of inequalities in relation to sustainable development: this can help reduce inequalities within their own workforces more effectively, and also reduce the risks of missing their decarbonisation targets. For large, complex socio-technical systems, such as cement and concrete, it is vital for consideration of inequalities to inform strategic planning with regards to decarbonisation and sustainable development.
