How are states spending federal IIJA funds, and what are the climate consequences?

This table describes estimated the cumulative, net CO2e Emissions production or reduction compared to pre-IIJA emissions projections, based on Transportation Investment Strategies Tool GHG Cost-Effectiveness outputs.
States with negative, red outputs indicate an increase in GHG emissions due to IIJA spending, while those positive, green numbers represent a decrease and emissions saved relative to business as usual projections.
