Concrete, the most widely used construction material globally, has significant environmental impacts despite its durability and versatility. The cement and concrete industry is increasingly required to decarbonize its operations and products to reduce global energy-related CO2 emissions. This paper provides a comprehensive review of more than 800 studies and proposes ways to decarbonize the industry. A socio-technical perspective is used to assess key factors that will drive a net-zero transition in the long term.
Concrete is the most highly used construction material globally. This is largely due to its durability, versatility and manufacture from inexpensive and readily available materials. Although concrete has become an essential and ubiquitous construction material for modern society, its use has significant environmental impacts. The full cement and concrete lifecycle, from production to final disposal, accounts for nearly 10% of global energyrelated CO2 emissions with the majority of these emissions produced from cement, which is the binding material that holds concrete together. The cement and concrete industry (CCI), which is integral to global infrastructure development, is therefore confronted with a growing need to decarbonize its operations and products, as well as to support the decarbonization of associated end-user sectors. This paper provides a systematic and critical review of more than 800 studies to highlight ways in which the CCI can decarbonize. A socio-technical perspective is used to understand the full range of industrial and economic activities where a decarbonized paradigm for cement and concrete production is relevant. This perspective is further used to assess key technical, economic, social and political factors that will drive a net-zero transition in the CCI over the long term.
