The Maryland Department of Transportation (MDOT) is committed to minimizing adverse impacts, conserving natural resources, and integrating sustainability into all aspects of transportation systems. Our commitment extends to the environment, our customers, our staff and the communities in which we operate.

MDOT takes a comprehensive systems approach to environmental stewardship. This approach facilitates programs in air quality, climate adaptation and resiliency, land and water resources, energy management, and sustainable community enhancement.
