NAPA’s Verified EPD Tool

Emerald Eco-Label, NAPA’s verified Environmental Product Declaration (EPD) tool, makes it easy to quantify the environmental impact of an asphalt mix. Created by industry professionals and stakeholders and evaluated by sustainability experts, the Emerald Eco-Label EPD tool was developed in conformance with ISO 14025 and EN 15804, which establish principles and procedures for developing a Type III environmental declaration program and describes the potential environmental impacts of a product. ACCESS THE EPD TOOL HERE

CAPA hosted the first of two Industry Stakeholder meetings on April 20th.  CDOT provided an update on the HB 21-1303 "Buy Clean Colorado Act" and their efforts to make an effective start to Environmental Product Declaration (EPD) collection.  They also provided a summary of targeted /most impactful construction materials, a plan for successful implementation and and overview of Industry capability/readiness.  A working draft of the proposed specification and Protocol document were provided for stakeholder review and comment.  The second stakeholders meeting was held on April 27 and addressed Industry review comments and discussion of the next steps (approval/issue schedule, likely impacted projects and phased data collection for 2022 and beyond).  Key takeaways of the draft EPD Protocol include:

  • 13 Focus Bid Items - Limited to items based on industry readiness
  • Some items will be considered “on-deck” for future iterative growth
  • EPD Data Collection on Projects over $3 Million based on Engineers Estimate
  • Small Quantity/Cost Limits on EPD asks

Here is a new effort underway to help with the Environment and how asphalt can save the environment

BLACK is the new GREEN!

The National Asphalt Pavement Association (NAPA) has introduced two new publications, a sustainability report and a companion brochure. In announcing the new publications, NAPA President Mike Acott commented, "For decades, the asphalt pavement industry has been proactive in reducing the impact of its operations on the environment. The new report discusses some of the products we have developed – warm-mix asphalt, reuse/recycling, porous asphalt, and Perpetual Pavements – and shows how an accelerated deployment program could lead to even greater achievements." Click here to visit the National Asphalt Pavement Association website.
