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 (HP 622, 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 (LD 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. This committee was subdivided into four working groups centered around Maine’s built, coastal, natural, and social environments. These working groups were tasked with developing recommendations for adaptation action.

In February 2010 the coordinating committee highlighted the need for adaptation planning; data, monitoring, and assessment; information and awareness; and planning and coordination. The committed 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. This 2010 plan includes 118 goals to help prepare Maine for climate impacts.

In 2013, Governor Paul LePage vetoed a bill (L.D. 825) which would have authorized the Department of Agriculture, Conservation and Forestry to work with other state agencies to study the effects of climate change on Maine.

Maine is in the process of implementing the goals set forth in the 2010 plan.
