On May 17, 2016, the Supreme Judicial Court of Massachusetts ruled that the Massachusetts Global Warming Solutions Act requires MassDEP to promulgate new regulations that “impose a limit on [greenhouse gas] emissions that may be released, limit the aggregate emissions released from each group of regulated sources or categories of sources, set emission limits for each year, and set limits that decline on an annual basis” to meet the requirements of section 3(d).

On September 16, 2016, Governor Baker signed Executive Order 569 pdf format of Executive Order Climate Change Strategy
which directed the Executive Office of Energy and Environmental Affairs to coordinate and make consistent new and existing efforts to mitigate and reduce greenhouse gas emissions and to build resilience and adapt to the impacts of climate change. The Executive Order also directed MassDEP to promulgate regulations that satisfy the mandate of Section 3(d) of Chapter 21N of the General Laws by August 11, 2017 with the objective that these regulations ensure that the Commonwealth meets the 2020 statewide emissions limit mandated by the GWSA. These efforts will work together with current activities, as detailed in the 2015 Update to the Massachusetts Clean Energy and Climate Plan for 2020 pdf format of MA Updated Clean Energy and Climate Plan for 2020

MassDEP held stakeholder meetings on potential new greenhouse gas regulations in early November 2016, and received pre-proposal stakeholder feedback that informed development of the proposed regulations. The stakeholder meeting presentations and stakeholder pre-proposal feedback received can be found below.

A formal comment period on MassDEP's proposed regulations ended February 24, 2017. The public notice with dates that public hearings were held can be found here.
