The Maryland Department of the Environment (MDE) brings together grant, loan, and technical assistance programs supporting healthier communities, cleaner air and water, and a more sustainable future. These opportunities help local governments, nonprofits, farmers, schools, and private entities undertake environmental improvements, including drinking water system upgrades, wastewater treatment modernization, cleaner vehicle replacement, electric vehicle charging infrastructure, electronics recycling, and cleanup of illegal scrap tire stockpiles.
The portfolio spans climate resilience, Chesapeake Bay restoration, solid waste management, and electrification.

Other assistance helps local governments identify greenhouse gas reduction projects and supports local emergency planning. Across these activities, MDE seeks to advance environmental equity, safeguard public health, and meet Maryland’s climate and sustainability goals.
