From maritime commerce moving up and down the Chesapeake Bay to recreational activities like hiking in mountain Maryland or catching a wave in Ocean City, Maryland’s natural resources are among the state’s greatest assets. As the transportation sector is the largest source of greenhouse gas emissions in Maryland, protecting our natural resources and furthering our environmental stewardship is a key priority for MDOT. This Earth Month, we are highlighting several department projects and programs that are designed to protect the environment, support sustainable practices and further progress towards a variety of environmental goals in the state.
