GHG Emissions Inventory for Asphalt Mix Production in the United States

The asphalt pavement production industry has set an ambitious goal of achieving net zero greenhouse gas (GHG) emissions associated with the production of asphalt pavements. To reach net zero carbon, the industry must understand, identify, and continue to reduce both the carbon intensity of materials used in, and energy consumption associated with, the production of asphalt pavement mixtures. This report assesses and documents a cradle-to-gate emissions inventory for asphalt pavement mixtures for the years 2009-2019. This report is the first national cradle-to-gate assessment of GHG emissions associated with the production of asphalt pavement mixtures focused on the A1-A3 life cycle stages. Although this report provides an estimate for the national average GHG emissions associated with asphalt mix production, it is not an industry average Environmental Product Declaration (EPD) and should not be used as a benchmark for project-level decision making during procurement or project delivery.
