The State of Minnesota and MnDOT are committed to reducing greenhouse gas (GHG) emissions that contribute to climate change. In 2020, MnDOT began quantifying GHG emissions as part of the environmental review process.

Infrastructure Carbon Estimator

The FHWA Infrastructure Carbon Estimator (ICE) Version 2.1 is a planning and pre-engineering analysis tool that provides lifecycle estimates of energy and GHG emissions based on national emission and energy use factors for materials and construction activities.

ICE’s is intended for the following applications:

  • Pre-engineering analysis when detailed project specifications are not available e.g., construction material quantities
  • Estimate energy/GHGs from on-road vehicle travel
  • “Footprint” analysis of individual facilities or transportation networks
  • Evaluate strategies to reduce energy and GHGs from construction and maintenance as a starting point for more detailed analysis

The ICE tool was updated by ICF International as part of FHWA Transportation Pooled Fund TPF-5(362) with FHWA and departments of transportation from Minnesota (lead), California, Colorado, Iowa, New York, Texas, and Washington State.

For more information about the ICE Tool, please view the Final Report and User's Guide.

Note: When opening the tool, please ensure that macros is enabled for Microsoft Excel.

Minnesota Infrastructure Carbon Estimator

The Minnesota Infrastructure Carbon Estimator (MICE) is the Minnesota-specific version of ICE. It differs from ICE in the following ways:

  • Minnesota-specific motor vehicle emissions factors to calulate exhaust emissions from vehicles
  • Option to analyze Build/No-Build project alternatives
  • Minnesota-specific inputs for mitigation, lighting, lane width, and others
