Good News—and Bad—about Fossil Fuel Power Plants in 2023 

Union of Concerned Scientists

And fossil fuel power plants may not stick to their retirement schedules for a variety of reasons. In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data.

Don’t Believe the Lies: Five Facts to Consider as the UN’s COP27 Comes to a Close

Union of Concerned Scientists

Union of Concerned Scientists’ (UCS) research shows that top fossil fuel producers’ emissions are responsible for as much as half of global surface temperature increase. Updated analysis from 2020 shows that emissions traced to the 88 largest carbon producers contributed approximately 60 percent?of

Ask a Scientist: Two Dozen States Can Meet 100 Percent of Electricity Demand with Renewables by 2035

Union of Concerned Scientists

The shift from fossil fuels in the 100-percent RES scenario reduces the amount of toxic power plant air pollution much more than what we called a “no-new-policy,” or business-as-usual, scenario. Emissions of sulfur dioxide and nitrogen oxides from power plants in alliance states drop 88 percent and 77 percent respectively by 2040.

Too Many Gas Power Plants are the Problem Not the Solution

Union of Concerned Scientists

We need more electricity to transition our homes and cars off fossil fuels, but we can’t afford to let that electricity come from more gas power plants. Over the year, those plants emitted 661 million metric tons of carbon dioxide, more than 13% of the US’s energy-related carbon dioxide emissions.

A 100% Renewable Energy Future is Possible, and We Need It

Union of Concerned Scientists

The shift from fossil fuels in the 100% RES scenario reduces the amount of harmful air pollution from power plants much more than in our “No New Policy”/business-as-usual scenario. Just as important, cleaning up the power grid can also decrease carbon dioxide (CO 2 ) emissions. And our modeling shows renewables’ power.

Ask a Scientist: Gas Plants Disproportionately Harm Marginalized Communities

Union of Concerned Scientists

Responsible for 12 percent of all US global warming emissions from human activities, methane traps significantly more heat per molecule than carbon dioxide, making it 86 times more harmful for the first 20 years after it is released into the atmosphere. Its primary component is methane. First, there’s air pollution.

Reliance on Gas Power Plants Fuels Inequity

Union of Concerned Scientists

In New England, the percent of people of color living near fossil fuel power plants is up to 23.5 Even as some parts of the country transition away from fossil fuel infrastructure, the retirement of gas plants has become another driver of inequity. Most notable of these polluting emissions are nitrogen oxides (NOx).
