This page provides an overview of the steps Maine is taking to prepare for the impacts of climate change.
In 2003, the Maine Legislature charged the Department of Environmental Protection (DEP) with developing a mitigation plan to reduce greenhouse gas emissions (H.P. 622 — L.D. 845, An Act To Provide Leadership in Addressing the Threat of Climate Change). This directive led to the development of the 2004 Maine Climate Action Plan.
In 2009, the legislature directed DEP to develop adaptation options for the state in order to prepare for climate impacts (L.D. 460, To Evaluate Climate Change Adaptation Options for the State). In response, DEP created a coordinating committee composed of representatives from the private and public sector to develop recommendations for adaptation action. This committee was subdivided into four working groups centered around Maine’s built, coastal, natural, and social environments.
In February 2010, the coordinating committee highlighted the need for adaptation planning; data, monitoring, and assessment; information and awareness; and planning and coordination. The committee presented its report, People and Nature Adapting to a Changing Climate: Charting Maine’s Course, to the Joint Standing Committee on Natural Resources of the 124th Maine Legislature (“2010 Plan”). The 2010 Plan includes 118 goals to help prepare Maine for climate impacts.
In June 2019, Maine Governor Janet Mills signed into law "An Act to Promote Clean Energy Jobs and to Establish the Maine Climate Council." The act states that the impacts of climate change have created an "emergency within the meaning of the Constitution of Maine" and find that the law is "immediately necessary for the preservation of the public peace, health and safety." To address the state's climate emergency, the act includes multiple provisions related to climate adaptation and resilience. Specifically, the act created the Maine Climate Council to advise the state's governor and legislature on ways to mitigate, prepare for, and adapt to the impacts of climate change. A Scientific and Technical Subcommittee and sector focused Working Groups will be established under the Council to carry out climate adaptation and mitigation research, and update Maine’s Climate Action Plan. The plan is to address prescient information on climate impacts to Maine's sectors, ecosystems, and communities most at risk, and the Council will recommend ongoing strategies and actions for climate adaptation and resilience. The Council must meet at least every three months, beginning no later than October 1, 2019, and present the governor with an updated Climate Action Plan by December 1, 2020.
Interagency Work Groups
On November 15, 2013, GovernorPaul LePage sent a letter (see Appendix A) to the Commissioner of the Department of Environmental Protection to establish the Environmental and Energy Resources Work Group (EERWG) to identify climate change vulnerabilities facing the state’s built and natural environment and create strategies to coordinate complex solutions across agencies. EERWG was composed of five state agencies and a representative from the Governor’s Energy Office. The governor asked EERWG to create a comprehensive list of agency actions “that address or respond to observed climate changes in the environment, mapping of natural resources or the study of impacts to industry consequent of environmental change factors” and then recommend how to improve coordination across agencies to increase efficiency.
In September 2014, EERWG released the Monitoring Mapping, Modeling, Mitigation, and Messaging report, which included concrete, voluntary recommendations to improve interagency adaptation efforts. In 2018, the Maine Interagency Climate Adaptation (MICA) Work Group, which succeeded EERWG, released a 2018 update to the 2013 report. The MICA Work Group consolidates state resources for adaptation, resilience, and mitigation, including through the Maine Adaptation Toolkit, and encourages interagency collaboration and cross-agency projects. The 2018 update, Maine Prepares for Climate Change 2018 Update, tracks progress on the 2010 Plan and elaborates on additional climate adaptation recommendations and strategies, emphasizing the state’s need to continue to improve interagency coordination in this area.
These pages highlight the progress Maine is making in implementing the goals set forth in the 2010 Plan. These pages will be updated in the future after Maine releases its Climate Action Plan in December 2020. Other resources from the Adaptation Clearinghouse, which have been developed and adopted to help Maine prepare for the impacts of climate change, are featured in the chart below.
The Georgetown Climate Center’s State Adaptation Progress Tracker, which tracks the progress states are making in implementing adaptation plans, was supported by the MacArthur Foundation.
