California’s Concrete producers are engaged in a wide range of initiatives to reduce the carbon footprint of their product and from their operations. Nationally, concrete producers have reduced their carbon footprint by 21% since 2014. These are examples of their sustainability initiatives:

  • Use of recycled concrete materials
  • Reuse of returned fresh concrete.
  • Using supplementary cementitious materials, such as fly ash, slag, and rice hulls
  • Recycling materials from waste streams, such as glass and plastic
  • Converting their mixer truck fleets to alternative fuels
  • Sequestering carbon from manufacturing operations in concrete
  • Evaluation of environmental impact in Environmental Product Declarations (EPD)

Resources to assist with providing low-carbon concrete:
