Massachusetts Global Warming Solutions Act

In 2008, Massachusetts Governor Deval Patrick signed the Massachusetts Global Warming Solutions Act (GWSA). The Act aims to mitigate Massachusetts greenhouse gas emissions by 10-25 percent below 1990 levels by 2020 and by 80 percent by 2050. Synapse worked in conjunction with Eastern Research Group and other sector experts to assist DOER in developing and analyzing policy instruments to help achieve these goals, and performed modeling to project the costs and impacts of various existing and potential greenhouse gas mitigation policies.
