Gas Plants Have a Real Climate Problem. So Do Some Proposed Approaches for Addressing It. 

Union of Concerned Scientists

The second perspective we offer in our new analysis comes from pulling back the lens to take into account not just carbon at the smokestack, but also the carbon from other steps in the process, as well as other gases that also trap heat when thrown up into the atmosphere.

Replacing California’s Oldest and Dirtiest Cars Will Save Money and Lives

Union of Concerned Scientists

Older vehicles (pre-2004) make up 19% of the state’s passenger vehicles and only 12% of miles driven, yet they emit almost 3 times as much smog-forming, nitrogen-oxide pollution as all 2004 and later vehicles combined. These pollutants react in the atmosphere to form harmful particulate matter pollution known as PM 2.5.

Oil Refineries: A Deadly Industry

Union of Concerned Scientists

Examples are benzene, hydrofluoric acid, particulate matter, sulfur dioxide, nitrogen oxides, and many, many other toxic pollutants. It has been estimated that globally oil processing is responsible for about 15 percent of all VOCs released into the atmosphere. which is formed in the atmosphere from precursor gases such as NOx.

Has Gasoline Use in California Peaked?

Union of Concerned Scientists

Each gallon of gasoline used results in 19 pounds of carbon dioxide emissions to the atmosphere, and the extraction of oil, refining, and distribution of gasoline results in the equivalent of an additional 4.5 Eliminating gasoline combustion also means getting rid of harmful pollutant emissions like nitrogen oxides and reactive organic gases.

The State of the Air in 2024? Not Great

Union of Concerned Scientists

come from reactions of industrial pollutants (nitrogen oxides and sulfur oxides) with sunlight and unfinished fuel combustion. Ozone plays a dual role in our atmosphere. Coarse particles (PM10, that is particulate matter that is 10 micrometers or less) include dust and pollen, fine particles (PM2.5)

The Supreme Court’s Latest Decision Is a Blow to Stopping Climate Change

Union of Concerned Scientists

Had the court ruled fully in favor of the EPA— or not taken the case at all —a much more meaningful dent in power plant carbon emissions would be within reach, while also delivering much greater reductions in other dangerous co-pollutants from burning fossil fuels such as particulate matter, mercury, nitrogen oxides and sulfur dioxide.

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. First, there’s air pollution.
