The ISO New England Electric Generator Air Emissions Reports available below provide a comprehensive analysis of New England electric power generator air emissions (nitrogen oxides [NOX], sulfur dioxide [SO2], and carbon dioxide [CO2]) and a review of relevant system conditions.
During the ten-year period from 2010 through 2019, native system emissions decreased: NOX by 55%; SO2 by 97%; and CO2 by 41%. The emissions decline during this period reflects shifts in the regional generation mix, with increases in natural gas-fired, solar and wind generation offsetting declines in coal- and oil-fired generation.
Part of the comprehensive planning activities that ISO New England performs include evaluating the environmental impacts of resource and transmission facilities needed to maintain the reliability of New England’s power system. The quarterly environmental reports below track the impact of state and federal environmental requirements on the reliability and operation of New England power system and, in turn, the environmental consequences of its operations.
