FHWA Steps Up Efforts to Tackle Greenhouse Gas Emissions from Highway Construction with $7.1 Million for ‘Climate Challenge’ Participants

Challenge will advance the use of sustainable pavements and quantify environmental impacts

As part of the U.S. Department of Transportation’s ongoing work to address climate change, the Federal Highway Administration (FHWA) today announced $7.1 million for 25 state departments of transportation involved in FHWA’s Climate Challenge. FHWA launched the Climate Challenge Initiative earlier this year to quantify the impacts of sustainable pavements and to demonstrate ways to reduce greenhouse gas emissions in highway projects using sustainable construction materials. The new funding is being announced as part of the Federal Buy Clean Initiative to promote the use of American-made, lower-carbon construction materials in Federal procurement and Federally-funded projects.

“As the sector of the U.S. economy that produces the most carbon emissions, transportation must be a central arena for solutions in our fight against climate change,” said U.S. Transportation Secretary Pete Buttigieg. “Sustainable pavement may not sound glamorous, but it’s an example of the kind of creative and important work needed in this moment, and we’re proud to support innovative efforts in this field across the country.”

The Climate Challenge Initiative is part of a department-wide effort announced during Earth Week 2022 to encourage transportation agencies and others to identify innovative ways to reduce transportation sector greenhouse gas emissions. The challenge presents a unique opportunity to improve the sustainability of pavement structures and work towards net-zero emissions. It also supports the new Bipartisan Infrastructure Law funded Carbon Reduction Program (CRP) announced earlier this year that unlocks $6.4 billion in formula funding over five years for states and localities to develop carbon reduction strategies and to address the climate crisis.

“To achieve our goal of addressing climate change, we must encourage investment in more sustainable transportation, and the Climate Challenge Initiative is one way to do that,” said Acting Federal Highway Administrator Stephanie Pollack. “Today the Climate Challenge Initiative will provide state transportation agencies with resources to inform pavement engineering decisions that support reduced environmental impacts in highway transportation projects. This is critical in the Nation’s all-of-the-above efforts to achieve our Net Zero emissions goals.”

The Climate Challenge Initiative provides funding, training, and technical assistance to help state departments of transportation (DOTs) and other public sector stakeholders explore the use of Life Cycle Assessments (LCAs) and Environmental Product Declarations (EPDs). Together LCAs and EPDs illustrate the environmental impacts of pavement materials and products, including quantifying greenhouse gas emissions. These standard practices can inform decisions for highway construction projects, pavement material, and design.

During this first cycle of the Climate Challenge Initiative, FHWA plans to host peer exchanges and webinars and develop case study reports to share lessons learned, outcomes, and next steps for further implementation. Over the next two years participants will receive training and work with various stakeholders including industry and academia to implement projects that quantify the environmental impacts of pavements using LCAs and EPDs.
