US: Providing a direction to carbon neutrality for the cement and concrete sectors by 2050, the Portland Cement Association (PCA) has published a roadmap. It says that the strategy document demonstrates how the US cement and concrete industry, along with its entire value chain, can address climate change, decrease greenhouse gases and eliminate barriers that are restricting environmental progress. It added that the document is a ‘major step’ towards engaging US policymakers, industry partners and non-government organisations.
The PCA’s roadmap also outlines a number of reduction strategies across the various phases of the built environment including production at cement plants, construction including designing and building and everyday infrastructure in use. It also recognises five main areas of opportunity: clinker; cement; concrete; construction; and carbonation (using concrete as a carbon sink).
Moreover, the roadmap also noted the necessity of carbon capture and storage/utilisation (CCUS) for reducing CO2 emissions from cement production. However, is pointed out that there are no commercial-scale CCUS installations at any cement plant within the US, location and permitting challenges remained and that infrastructure investment would be required to deal with the captured CO2 .
