The MIT Concrete Sustainability Hub (CSH) has released a research brief that presents pathways to net-zero concrete pavements by 2050. The three-page brief, written by Dr. Hessam AzariJafari of the CSH describes the need to address strategies and methods for offsetting and reducing embodied greenhouse gas emissions in concrete pavements.

A few of the key messages include:

  • Concrete mixtures with zero embodied carbon can be attained using the simultaneous benefits of reduction, replacement, reuse, recycling, and CO2 sequestration.
  • Technical and economic barriers, as well as market acceptance, should be considered in future work to investigate their feasibility in different regions.
  • The order of implementation will determine the contribution of each attribute to the total GHG savings.
