Following the passage of the Inflation Reduction Act in 2022 and the Bipartisan Infrastructure Law in 2021, historic amounts of federal funding are going to states to invest in infrastructure projects, including transportation. The Biden administration has promoted the use of those funds to address environmental and equity concerns. However, most decisions about how the money is spent fall to state officials, writes Daniel Vock, senior reporter for Route Fifty.

To shine a light on how that’s panning out, the Natural Resources Defense Council (NRDC) recently analyzed and ranked the 50 U.S. states according to how well they are directing money from the infrastructure law to improve equity and climate outcomes in their transportation networks.

“A lot of what you read is the amount of money that is being spent, and that’s seen as a good thing in and of itself. But we would argue that what's more important than the amount of money is literally what is being built on the ground and who that is serving,” John Bailey, an NRDC advocate and one of the primary authors of the report, told Route Fifty.

“Researchers based their rankings on 19 separate factors, including the greenhouse gas impact of road projects, the deployment of electric vehicle chargers, efforts to encourage residents to avoid car trips, and procurement policies that promote women- and minority-owned businesses,” reports Vock.

According to NRDC’s report, the 10 states doing the most and the 10 states doing the least to improve equity and climate outcomes in their transportation networks are as follows:
