The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions.
Coal trains and terminal operations add a significant amount of fine particulate matter (PM 2.5 ) pollution to urban areas—more so than other freight or passenger trains— according to a study conducted in Richmond, California, by the University of California, Davis. The results indicate coal trains add on average 8.32

The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.
Air pollution was responsible for 1.1 Air pollution was responsible for 1.1 Deaths attributable to household air pollution and ambient particulate matter (PM 2.5 ) air pollution in Ethiopia, Ghana, Rwanda, and overall in Africa, 1990–2019.

These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions.
Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The burning of coal releases more carbon dioxide than other fossil fuels, as well as comparatively high levels of other pollutants, including sulfur dioxide, nitrogen oxides, and particles such as ash.

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. —Mark Jacobson.

It is causing 1.67
In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. But the rapid reduction of PM 2.5

Absolute ambient PM 2.5
The US Environmental Protection Agency (EPA) has proposed Clean Air Act standards to reduce CO 2 emissions from fossil-fuel fired power plants (electric utility generating units, EGUs). The proposed rulemaking establishes separate standards for natural gas and coal plants. Background. In the decision in Massachusetts v. Earlier post.)
Plastics are on track to contribute more greenhouse gas emissions than coal plants in the US by 2030, according to new report by Beyond Plastics, a nationwide project based at Bennington College in Vermont. These 35 cracker facilities release as much GHG as 35 coal-fired power plants. million tons of GHG each year.
The US Environmental Protection Agency (EPA) released its fourth year of Greenhouse Gas Reporting Program data, detailing greenhouse gas pollution trends and emissions from large sources and suppliers broken down by industrial sector, geographic region and individual facilities. Power plant emissions have declined by 9.8%
A team of researchers, led by Professor Gavin Shaddick at the University of Exeter, has shown that, despite global efforts to improve air quality, half of the world’s population is exposed to increasing air pollution. In some regions, sand and desert dust, waste burning and deforestation are additional sources of air pollution.

High-risk patients who live in heavily populated or polluted areas should recognize the danger and take precautions, Bragg-Gresham says. concentration.
The study’s findings highlight the importance of considering exposures—especially the proximity of emissions to people—when evaluating environmental health impacts for EVs, the team said. For EVs, combustion emissions occur where electricity is generated rather than where the vehicle is used. 90% is from coal.
