Mitigating the Carbon Footprint of Concrete - 1.25 PDH (LA CES/HSW) / 1.0 GBCI SITES-Specific CE

Expiration Date: Dec 31, 2026

Credits: None available.

Members: $40.00
Associates: $30.00
Students: $0.00
Standard: $50.00


The carbon footprint from the billions of tons of concrete placed each year is substantial, resulting in nearly 8% of total global emissions. This session will provide attendees with tools to reduce the carbon footprint of concrete through use of high-volume cement substitutes, concrete mix optimization, and carbon sequestering technologies.

The GBCI course ID for this course is 920025327, providing SITES-specific CE hours required to maintain SITES AP credentials. Participants will need to pass the exam at the end of the presentation in order to receive a certificate of completion. Participants will need to self-report CE hours through their credentials account on https://sitesonline.usgbc.org.

Please complete a brief evaluation of this Online Learning presentation.

Learning Objectives:
  • Understand the carbon impacts of concrete and Portland Cement, and methods to mitigate the impacts.
  • Identify Portland Cement substitutes, both natural pozzolans and industrial byproducts, and the effects they have on concrete structures during placement and use.
  • Understand technologies for carbon sequestration in cement, manufactured aggregates, and concrete.
  • Recall the benefits, costs and challenges of technologies and materials to reduce the carbon footprint of concrete structures.
