USGBC California Hosts an Innovative Carbon Forward Summit in L.A.

A recent industry gathering in Los Angeles, the Carbon Forward Summit, brought together building professionals to talk about cutting the carbon footprint of construction ahead of the 2028 L.A. Olympics and Paralympics. The focus was on concrete and other building materials, since the Olympics will drive a wave of new construction in the city. Panels covered "low embodied carbon" concrete, meaning concrete made with materials or processes that release less carbon dioxide than standard mixes. Examples included concrete made with combusted biosolids, ground glass, and other alternative ingredients, along with newer materials like hemp-based cement blocks and mass timber.

Speakers also discussed LEED v5, the newest version of a widely used green building certification system, which now requires projects to account for the full lifecycle carbon impact of their materials, not just energy use once a building is running. The Intuit Dome in Inglewood, home to the LA Clippers, was highlighted as an example of this kind of low-carbon construction already in practice. Data centers came up too, with some discussion of whether their waste heat could eventually be captured and reused for heating elsewhere, though this idea remains largely conceptual.

For homeowners, this event does not create any new program, rebate, or rule to act on. It signals a direction the building industry and California policy may be heading: more scrutiny of the carbon embedded in construction materials, not just a building's energy use. Over time, that shift could affect the products and certifications available to homeowners doing renovations, but no specific homeowner incentives or requirements came out of this summit.
