Governor's Council on Climate Change 

Taking Action on Climate Change and Building
a More Resilient Connecticut for All
Thumbnail Image of GC3 Report Cover

On September 3, 2019, Governor Ned Lamont issued Executive Order No. 3, re-establishing and expanding the membership and responsibilities of the Governor’s Council on Climate Change, also known as the GC3. The GC3 was originally established in 2015 by Governor Dan Malloy.  In addition to continuing to address mitigation strategies to reduce greenhouse gases, the newly expanded GC3 will also consider adaptation and resilience in the face of climate change impacts.

The GC3's membership includes 23 members from state agencies, quasi-public agencies, businesses, local governments, and nonprofits, and is tasked with two primary objectives and related tasks:

Building a Low Carbon Future for Connecticut

1. Monitor and report on the state’s implementation of the greenhouse gas emissions reduction strategies set forth in the inaugural GC3’s December 2018 report Building a Low Carbon Future for Connecticut: Achieving a 45% GHG Reduction by 2030. This includes tasks such as:

  • Evaluating opportunities for equitably distributing the costs and benefits of implementing the recommended GHG mitigation strategies, specifically addressing any disproportionate impact on environmental communities;
  • Assessing and describing how GHG reduction strategies are being integrated into existing and new state agency planning efforts;
  • Evaluating the efficacy of existing and proposed policies and regulations aimed at reducing GHG emissions; and
  • Identifying new and emerging GHG mitigation strategies that maximize climate change adaptation and resiliency.

2. Develop and implement adaptation strategies to assess and prepare for the impacts of climate change in areas such as infrastructure, agriculture, natural resources, and public health. This includes tasks such as:

  • Reporting on the alignment of climate change adaptation strategies incorporated into state agency planning processes and documents.

Meetings of the GC3, its subcommittees, and working groups continue to be noticed and are open to the public:

History of the GC3

The GC3, originally established in 2015 by Governor Dannel P. Malloy’s Executive Order No. 46, was formally tasked with examining the effectiveness of existing policies and regulations designed to reduce greenhouse gas emissions and identify new strategies to meet the state’s greenhouse gas emissions reduction target of 80% below 2001 levels by 2050. The Council was also tasked with developing a mid-term greenhouse gas reduction and to identify strategies to achieve the chosen target.  The Council submitted its recommendations on December 18, 2018 when it released the report Building a Low Carbon Future for Connecticut: Achieving a 45% GHG Reduction by 2030. All previous meetings are archived below.
