is true for road construction: emissions that occur from the manufacturing of raw materials, asphalt mix production and paving are embodied. The emissions that occur after a road has been paved with asphalt are operational. Joseph Shacat said, “What we are seeing is that agencies at the federal, state, and local level are beginning to require contractors to submit EPDs because they want to know what the environmental impact is of the products they purchase. Once a government organization has the report, the organization can require or incentivize lower emissions on projects.“ After gathering specific information about each company, the RFI asked about seven areas of interest. The first was cradle-togate EPDs for asphalt mixes: how they are generated, whether there is any non-EPD documentation, and whether EPDs have attracted business customers. The second was the question of market demand for low embodied carbon asphalt and what strategies are being used to reduce carbon emissions, such as EPDs, and whether the responding company has a dedicated or specialized sustainability staff. The third RFI question pertained to companies producing or supplying low embodied carbon asphalt, and the production details and cost comparisons about innovative or outstanding environmental attributes, and the performance attributes associated with manufacturing, installing or using asphalt. The fourth question was about obstacles (technical, economic, or regulatory) and for suggestions about reducing asphalt manufacturing’s carbon footprint. The final three questions related to product testing, states using environmentally preferable asphalt, and the location of asphalt plants. They wanted to know about challenges, implementation lessons and best practices when using environmentally-preferable asphalt. They also wanted to know if mobile plants are used at remote sites and if the company could recycle pavement on-site. Richard Willis, Ph.D., NAPA’s vice president for engineering research and technology, attended the Utah Asphalt Conference 2022, held Feb. 1-2, 2022, at Mountain America Expo Center. While there, he also presented about EPDs. UAPA contacted him after the conference to talk about EPDs and The Road Forward. He said, “The Road Forward presents an opportunity for contractors in Utah and throughout the country to become better businesses. The program allows everyone to look holistically at how their businesses are positively affecting the community.” Mr. Willis and Mr. Shacat are part of the task force leadership that produced The Road Forward program.
