Forty cement and concrete manufacturers representing 80% of the global cement industry volume outside China have published a roadmap to reach net zero carbon emissions within 30 years.
Around 14 billion m³ of concrete was produced globally in 2020 and the global cement and concrete products market’s value totalled $440 billion, according to the association. The GCCA roadmap includes an immediate pledge to reduce greenhouse gas emissions by up to 25% by the end of this decade.
“We will accelerate our CO₂ reductions through … increased clinker substitution – including fly ash, calcined clays, ground granulated blast-furnace slag and ground limestone; fossil fuel reductions and increased use of alternative fuels; improved efficiency in concrete production; improved efficiency in the design of concrete projects and use of concrete during construction, including recycling; investment in technology and innovation; and carbon capture usage and storage technology (CCUS) and infrastructure development,” GCCA said.
Prominent members of the association include HeidelbergCement, Holcim Group, CEMEX and several large Chinese manufacturers. GCCA has antipodean affiliates including Cement Concrete & Aggregates Australia (CCAA); the Cement Industry Federation (CIF) of Australia; and Concrete NZ. Members produce Portland cement clinker and other natural cementitious clinkers.
CEO of HeidelbergCement, Dominik von Achten, said swift and decisive political action was needed to create the right framework conditions, particularly in the area of CO₂ infrastructure and market incentives for low-emission building materials.
