On behalf of Green Energy Consumers Alliance (GECA), Researcher Sagal Alisalad, Senior Researcher Joshua R. Castigliego, and Principal Economist Liz Stanton, PhD, prepared a report analyzing the costs of low-to-moderate income (LMI) emissions reductions measures in Massachusetts. AEC staff assessed LMI-specific emissions reduction measures that could be implemented in Massachusetts by 2030 and developed a marginal abatement cost curve showing eight measures from lowest to highest cost. AEC’s analysis found that the eight measures would reduce emissions by 0.2 million metric tons (MMT) in 2030, about 7 percent of the 2.9 MMT needed to meet the Commonwealth’s 2030 climate targets, and that the eight measures total 2.8 MMT of lifetime CO2e reductions and have a net societal benefit, or cost savings, of $7.3 billion.
