Maryland and the United States confronted unprecedented challenges in 2020. As the climate crisis continues to grow, the COVID-19 pandemic precipitated public health and economic emergencies and exacerbated economic, social, and racial inequities that have plagued disadvantaged an​d overburdened communities for decades. Amid these mounting crises and a nationwide reckoning with structural racism, the Maryland Commission on Climate Change continued its work to improve Maryland’s response to climate change. Through this report, the Commission offers a series of recommendations to the Governor and General Assembly to enhance the state’s efforts in climate change mitigation, adaptation, and resilience, to better incorporate environmental and climate justice into the state’s climate approach, and to more meaningfully engage with disadvantaged and overburdened communities.​

Recommendations to the Commission by its four working groups form the crux of the ​report.​
