This session will provide comprehensive information to decarbonize site construction details. We will explore methods to reduce the embodied carbon of landscape structures including pavements, walls, decks, railings, and other site structures. Resources and techniques for measuring and evaluating the carbon footprint of details and materials will be discussed.

Learning objectives:

  • Understand embodied, operational, stored, and sequestered carbon, and how these concepts are applied in design and construction detailing.
  • Explore a wide range of construction materials and details to understand their carbon impacts, along with methods to reduce the impacts in all life-cycle phases.
  • Identify sources of data to assist with the comparison of embodied carbon in materials and details.
  • Explore viable decarbonization strategies for a variety of site structures including pavements, walls, decks, and railings.
