Carbon Dioxide Emissions from Fossil Fuel Electricity Generating Plants in New England About to Surpass RGGI Allowances

Carbon dioxide emissions from natural gas and oil-fired generation plants in New England have trended upward for the past 4 years despite the RGGI emission allowances have been decreasing each year.

2019:  18.1 million metric tons

2020:  19.5 million metric tons

2021: 21.0 million metric tons

2022:  22.3 million metric tons

2023:  21.9 million metric tons

The 2025 RGGI allowance of approximately 23.0 million metric tons calculates to 43.7 metric tons per minute. 

ISO-NE reports July 2025 natural gas-fired electricity production, minute by minute, varies between 9000 and 12000 megawatts which correlates to 60 to 75 metric tons of C02 per minute.

RGGI carbon dioxide charges to fossil fuel plants add $10 per megawatt hour to wholesale costs.

    Who are these people setting up an “allowance?

    China increases its CO2 by at least 100 million ton EACH YEAR.

    It is off-the-charts idiotic for people with small brains and self-serving hearts to “worry” about New England, which has one of the lowest CO2/kWh grids in the the US
