We are writing to share the perspective of the aggregates, cement and concrete industries about the possible impacts of the America’s Revegetation and Carbon Sequestration (ARC) Act. We represent more than 600,000 workers at thousands of aggregates, cement and concrete businesses across the country who manufacture and deliver critical materials for our nation’s built environment. Our members collectively serve every residential, commercial, and public works project in the United States and generate more than $100 billion in economic activity each year. We have significant concerns with policies and programs that promote specific buildings materials. Every day, concrete construction competes with wood construction for market share in the low- and mid-rise residential and commercial construction market. Engineers and construction professionals make decisions about which materials to use to meet the codes, standards and specifications of a project. For these reasons, we are concerned with provisions of the ARC Act that promote mass timber construction. We believe that decisions about the use of construction materials should be left to the discretion of engineers and construction professionals.
