Asphalt is America’s most recycled material. 

But recycling is just one reason that asphalt is the most sustainable pavement. Asphalt pavements that are designed and constructed as Perpetual Pavements never need to be removed and replaced. Our industry continuously explores methods and practices to contribute to a sustainable infrastructure and a healthy environment for generations to come. 

GHG Emissions Inventory for Asphalt Mix Production in the United States

This first-of-its-kind report documents the asphalt pavement's contribution to GHG emissions nationwide, including avoided emissions achieved with current technologies, along with comparisons to related sectors and research needed to continue reducing emissions. (SIP-106, June 2022)

Tools for the Industry

NAPA offers a number of tools that help asphalt mix producers and contractors improve their environmental performance.



Take a deeper dive into specific pavement-related sustainability topics.

Member Benefit – GBI Professional Certification

As a special member benefit, employees of NAPA member companies can earn professional certifications from the Green Building Initiative (GBI) at no cost. GBI administers the Green Globes sustainability rating system for buildings and the Guiding Principles Compliance Assessment Program for federal agencies. There is a separate credential for each of the two programs:

  • Green Globes Professional (GGP)
  • Guiding Principles Compliance Professional (GPCP)

Candidates must meet the minimum qualifications and submit an application form or résumé to GBI. Once approved by GBI, candidates will receive access to a certification package which includes training materials, final exam, and initial two-year certification. More details about each of the programs can be found on the GBI website

The application fee ($75) and the certification package ($750) is waived for NAPA members. 

If you’re interested in earning either of these two credentials, please contact Joseph Shacat. This is a limited opportunity. Access will be granted on a first-come-first-served basis.
