Life cycle assessment and environmental product declaration services provider WAP Sustainability has launched Theta EPD for Aggregates with National Stone, Sand & Gravel Association support. The first tool of its kind programmed specifically for North American producers, Theta Aggregate builds on WAP’s expertise in LCA and EPD generation software for ready mixed concrete, concrete pipe, cement and slag. The firm offered LCA and EPD insights to NSSGA during the Product Category Rules update process—critical to ultimate document validation—while in turn learning from the group on specific aggregate industry needs. 

Theta Aggregate EPDs can be used as standalone stone or sand & gravel declarations, or  upstream inputs into Theta Concrete and other building product LCAs or EPDs. The tool joins  Theta EPD, the Buy Clean Compliance Software, which WAP Sustainability maintains to help producers meet green procurement initiatives like the General Services Administration’s Inflation Reduction Act-driven pilot for low embodied carbon construction materials. “Theta Aggregate offers an industry specific, simplified way to demonstrate requirements necessary within many states and on certain federal projects,” says NSSGA Vice President of Government & Regulatory Affairs Michele Stanley. “We have anxiously awaited the time to provide a tool like this for our members.”  

“Theta Aggregate is a huge improvement in ease of EPD creation for construction aggregates,” notes WAP Sustainability Manager Lianna Miller, who led the firm’s aggregate product LCA efforts. As the construction sector requests more transparency documentation on the life cycle impacts of products, she adds, the Theta family of EPD tools helps suppliers or manufacturers to measure, report and disclose the environmental impacts of their products accurately and efficiently.
