Maryland
Minerals and waste are the highest-emitting sectors in Maryland. The state’s landfills and cement plants generate nearly three-quarters of emissions from large industrial facilities. Industrial facilities are concentrated in the Baltimore and Washington, DC metropolitan areas.

- The top 20 emitters are shown on this map, coded by industrial sector. The size of the circles corresponds to emissions: the larger the circle, the higher the emissions.
- Disadvantaged communities (as determined by the federal government) are shaded blue.

- The inner circle provides a visual representation of the share of emissions generated by each industrial sector.
- The outer circle also indicates the share of a sector’s emissions generated in disadvantaged communities.
State Energy Policy:
Examining a state’s broader energy policy landscape is helpful when considering policies to support industrial innovation. Maryland enacted statutory greenhouse gas reduction targets in 2022 and updated its renewable portfolio standard in 2019. While these formal commitments are not prerequisites for innovative industrial policy, they can provide a supportive framework.
Streamlining permitting and establishing an efficient, transparent appeals process that engages local communities early, while providing clarity and assurances to project developers, are also key components of effective state energy policy. Discussing innovative industrial policy presents an opportunity for broader conversations about state energy policy, ensuring a mutually reinforcing strategy.
LEGISLATIVE context & opportunity:
The context below is not exhaustive and serves as an example of recent policies and programs, highlighting potential future opportunities. Please let us know if you are aware of additional efforts advancing industrial innovation in Maryland that we should highlight.
- Commercial & Industrial Grant Program is an annual program offering competitive grants for new construction and existing facilities to make energy performance improvements that exceed current codes or standards.
- A factsheet by the Regional Carbon Capture Deployment Initiative describes how carbon capture can reduce industrial emissions in Maryland, including economically feasible subsectors and facilities that qualify for the federal 45Q tax credit.
- Maryland’s Department of the Environment has a page that provides an overview of the state’s industrial sector and details several recent and ongoing efforts to innovate.
