Carbon Reduction Program

The Carbon Reduction Program (CRP) provides funding for road projects designed to reduce carbon dioxide emissions.

The Infrastructure Investment & Jobs Act (IIJA)/Bipartisan Infrastructure Law (BIL) established the Carbon Reduction Program to provide funds for projects designed to reduce transportation emissions, defined as carbon dioxide (CO2) emissions from on-road highway sources. 

WSDOT allocates CRP funds to Metropolitan Planning Organizations (MPO’s) for prioritizing and selecting projects that align with their regional priorities involving all entities eligible to participate in a public project.

Suballocation of CRP

65 percent of CRP funding is suballocated to MPOs based on population as follows:

  • Urbanized areas greater than 200,000 population.
  • Urbanized areas greater than 50,000 but no more than 200,000.
  • Urban areas greater than 5,000 but no more than 49,999.
  • Areas with population of 5,000 or less.

35 percent is available for use in any area of the state and allocated to WSDOT projects.

Types of projects eligible to receive CRP funding are:

  • A project to replace street lighting and traffic control devices with energy-efficient alternatives.
  • A transportation alternative project eligible under 23 USC 101(a)(29)
  • A public transportation project eligible under 23 USC 142, etc.

The development of a statewide Carbon Reduction Strategy is required to be developed no later than two-years after enactment and updated at least every four years.

The federal participation rate is 86.5 percent.
