The Role of Concrete in Life Cycle Greenhouse Gas Emissions of US buildings and Pavements

Changes to concrete production as well as in building and pavements systems—the largest consumers of concrete—can lead to more than 50% reductions in associated GHG emissions by 2050. Over this period, the operational phase of newly constructed buildings and pavements still generates most GHG emissions unless the electrical grid, heating, and transportation are decarbonized aggressively. Meeting decarbonization targets will require lowering the GHG emissions of concrete production as well as innovative uses to lower building and vehicle fuel consumption. Owing to their low abatement costs, several concrete solutions should be prioritized in climate change policies. More than one-third of the embodied impacts of building and pavement construction can be offset by implementing concrete solutions. Life cycle assessment inventory data and spreadsheet datasets have been deposited in OSF ().
