Clean energy will not just be a part of our economy. Clean energy
will define our economy in Maryland.”​
             - Governor Wes Moore​
On March 13th, at the Maryland Department of the Environment, Gov. Wes Moore announced Maryland’s adoption of the multi-state Advanced Clean Cars II rule. It requires manufacturers to continuously increase the share of electric vehicles they sell, reaching 100% of sales by model year 2035.

“Today, we’re talking about a major transformation that is going to define this administration—and that’s how we turn Maryland from a state powered by oil and gas to a state powered by clean energy,” said Governor Moore. “I am confident that the state of Maryland can and will lead the clean energy revolution.”

Climate Change Program

​MDE's Climate Change Program oversees the development and implementation of the state's plan for reducing greenhouse gas emissions and conducts the state's greenhouse gas emissions inventory​. The staff support the Maryland Commission on Climate Change, ​the Carbon Markets and Trees Commission, ​the Buildings Energy Transition Task Force​, the Building Energy Performance Regulations (BEPS) process, and they manage Maryland's membership in the Regional Greenhouse Gas Initiative (RGGI) and the U.S. C​limate Alliance. This program also ensures the state complies with climate change related state and federal laws.

The main cause of climate change is human activities, particularly the emission of greenhouse ​gases (GHGs) into the atmosphere. The Maryland Department of the Environment's (MDE) Climate Change Program is leading the state's efforts to reduce GHG emissions while creating jobs and benefiting the economy, as required by the Greenhouse Gas Reduction Act (GGRA). Although many initiatives throughout the State contribute to these efforts, the Regional Greenhouse Gas Initiative (RGGI) and the​ Commission on Climate Change​ are key efforts by MDE, each of which can be explored further by following the navigational links on top, left-hand side of this page. 

In November 2
018, a federal report ​advised that "climate change is affecting the natural environment, a​griculture, energy production and use, land and water resources, transportation, and human health and welfare across the U.S. and its territories."  ​The good news is that in Maryland, we have an action plan to combat it. 

Wi​th 3,100 miles of shoreline, Maryland i
s the fourth most vulnerable state to suffer the effects of sea-level rise associated with climate change. Rising sea levels and increased storm intensity could have devastating and far-reaching impacts on the Atlantic coast and the Chesapeake Bay ecosystem that affect the environmental, recreational, and economic benefits enjoyed by Marylanders and visitors. Although M​aryland's coastal areas may be considered particularly vulnerable, all areas ​of the state are at risk. In general, climate change alters the severity, frequency, or distribution of existin​g issues that are impacte​d either directly or indirectly by temperature and precipitation. This includes, but is not limited to: ​

  • Impacts on coastal, bay, and inland water quality parameters that may change the viable uses of surface water, such as for irrigation, recreation, or human consumption. MDE's Water and Science Administration's Climate Adaptation Goals and Strategies are available here. ​
  • More frequent disruptions to urban and coastal infrastructure in Maryland caused by extreme weather events and sea-level rise that may indirectly impact the economy of the region by restricting the flow of goods and affecting days worked;
  • Common stressors experienced among ecosystems, agriculture, fisheries, and forestry such as those caused by general changes in temperature and precipitation regimes; increased extreme weather events; and increased pressures from weeds, diseases, and pests;
  • Human health issues, including those affected by impacts on food and water supply, air quality, extreme weather events; and
  • A higher probability of negative outcomes for disadvantaged communities and individuals inherently more sensitive or with a reduced adaptive capacity for responding to the impacts of climate change.
To learn more about climate change and what Maryland is doing to combat it, read the 2030 Greenhouse Gas Reduction Plan and the progress report. MDE submitted the comprehensive plan to the Governor and the State Legislature on February 19, 2020, to coincide with the​ U.S.​A's return to the Paris Climate Agreement. For the national perspective, visit the U.S. Environmental Protection Agency (EPA), Climate Change in the United States And, for the international perspective, read the Intergovernmental Panel on Climate Change's (IPCC) latest report. ​

Maryland has set the most aggressive GHG emissions reduction goals in the nation. Under the Climate Solutions Now Act (CSNA)​ ​​of 2022, a new target has been established at 60% (over 2006 level) by 2031 and net-zero emissions by 2045. MDE currently is working on a conceptual road map due by t​he end of June 2023. The final plan is ​due at the end of the year.
