Major highway capacity expansion projects exceeding $100 million must undergo impact assessments for greenhouse gas emissions and vehicle miles traveled, with the Department of Transportation required to develop and fund corresponding multimodal transportation programs that fully offset the project's emissions to achieve net-zero or negative greenhouse gas impact

Beginning with the FY 2028-2033 Consolidated Transportation Program, all major capital projects must be evaluated annually for their greenhouse gas and vehicle miles traveled impacts, with results published by October 1 each year in draft form and with the final program

Multimodal offset programs must prioritize investments in overburdened and underserved communities impacted by the project, followed by the project region, then statewide, and may include transit improvements, pedestrian/bicycle facilities, transit-oriented development, roadway pricing, telecommuting initiatives, and micro-mobility options

Projects already in the Statewide Transportation Improvement Program with construction funding, funded for construction in the Consolidated Transportation Program, or that completed NEPA environmental review by June 30, 2026 are exempt from these requirements

The Department must establish annual statewide and regional declining greenhouse gas emission reduction targets consistent with Maryland's Climate Pollution Reduction Plan, and allocate funding in FY 2028 for travel demand modeling that accounts for induced demand and land use effects
