Industry, pavement owners, and other stakeholders are developing ambitious goals to significantly reduce greenhouse gas (GHG) emissions. Efforts to achieve these climate related goals will affect all aspects of the U.S. economy, including a new focus on reducing the embodied carbon emissions associated with constructing and maintaining America’s pavements and other infrastructure assets. Through the Infrastructure, Investment, and Jobs Act (IIJA) of 2021, the Inflation Reduction Act (IRA) of 2022, and other federal programs, unprecedented levels of federal funding will be used to reduce greenhouse gas (GHG) emissions throughout the U.S. economy. In the IRA, $4.5 billion is directed towards quantifying and reducing GHG emissions in the construction materials sector.
In 2022, NAPA released The Road Forward, a vision and long-range goal for the asphalt pavement community to achieve net zero greenhouse gas (GHG) emissions by 2050. This report supports The Road Forward by providing a reference document for decarbonizing asphalt pavements, covering the following topics:
-Understanding the sources and relative magnitude of GHG emissions throughout the entire life cycle of asphalt pavements.
-Exploring opportunities for agencies and industry to reduce GHG emissions using readily available technologies and practices.
-Identifying research needs to better quantify and further reduce GHG emissions associated with asphalt pavements toward an ultimate goal of achieving net zero GHG emissions.
-Providing an overview of key tools used to quantify GHG emissions and inform decision making.
This report focuses on specific actions that can be implemented by individual companies and agencies to reduce GHG emissions. The intended audience includes pavement engineers, asphalt mix producers, paving contractors, policy makers, and other stakeholders with an interest in reducing embodied carbon
emissions associated with asphalt pavements
