• To develop a model for quantifying green cement technology’s potential in reducing carbon emissions from the production of concrete, the analysis projects California’s cement consumption through 2035 using a combination of expected housing construction and linear projections, based on the previous decade of use, of other uses for cement.
  • As currently there has been heightened infrastructure investments as a result of federal, such as the Infrastructure Investment and Jobs Act (IIJA; the bipartisan infrastructure bill) and the Inflation Reduction Act (IRA), and state legislation, such as SB 1 (the Road Repair and Accountability Act of 2017), it is projected that cement usage increases in sectors such as roadways, bridges, and other public infrastructure through 2026 before dropping back to more usual levels. However, it is still projected that in 2035, overall cement usage will be higher than that of 2022. The projection does not include any predictions of major changes in cement usage, future infrastructure legislation, natural disasters and repair, or economic cycles, all of which can greatly influence cement consumption. Rather than being a prediction, the model is intended to illustrate the potential an aggressive decarbonization campaign can have on emissions.
