What You'll Learn
Power plants are the US's biggest polluters
The US has historically been the world's biggest carbon polluter, emitting about 334 billion tons (303 billion metric tons) of carbon dioxide since 1959, constituting approximately 21.5% of the global total. While the US has been surpassed by China in recent years, historical emissions and other factors must be considered when assessing the biggest polluters. The burning of fossil fuels, particularly coal, oil, and natural gas, for electricity generation, is the primary driver of the US's carbon emissions.
Coal-fired power plants are the most significant contributor to carbon pollution in the US, with coal supplying just under half of the country's electricity. These plants emitted more than 80% of CO2 pollution from US power plants in 2007 and accounted for 36% of the country's total CO2 pollution. Moreover, they release disproportionate amounts of smog- and soot-forming pollutants, toxic mercury, and other toxic air pollutants. The age of power plants also plays a crucial role, with older plants, particularly those built before 1980, being significantly dirtier.
To address this issue, the Biden administration has implemented new rules to limit pollution from fossil fuel-fired power plants, and several top-polluting plants have announced plans to close or convert to cleaner energy sources in the coming years. The transition to renewable energy sources, such as wind and solar power, is crucial in reducing carbon emissions and mitigating the impacts of global warming. By investing in clean energy technologies and reducing dependence on fossil fuels, the US can not only improve its environmental footprint but also enhance its energy security and mitigate the risks associated with relying on imports from unstable or unfriendly regions.

Coal is the dirtiest fuel
The United States relies heavily on outdated technology and limited resources for most of its electricity needs. The vast majority of American electricity comes from burning fossil fuels—coal, oil, and natural gas—and from nuclear power. Fossil fuels have a high carbon content due to their origins as fossilized, buried remains of plants and animals.
Coal is the biggest culprit and the dirtiest of all fuels. Coal supplies just under half of America's electricity, more than any other source. Coal has the highest carbon content of any fossil fuel per unit of energy, meaning that burning coal for electricity produces more carbon per kilowatt-hour generated than burning oil or natural gas. America's fleet of coal-fired power plants emitted more than 80% of CO2 pollution from U.S. power plants in 2007 and 36% of the total U.S. CO2 pollution. In 2022, CO2 emissions from burning coal for energy accounted for about 19% of total U.S. energy-related CO2 emissions and for about 55% of total CO2 emissions from the electric power sector.
Coal-fired electricity emits copious amounts of carbon pollution, as well as disproportionate amounts of smog- and soot-forming pollutants, toxic mercury, and other toxic air pollutants. Several principal emissions result from burning coal, including sulfur dioxide, nitrogen oxides, particulates, carbon dioxide (CO2), mercury and other heavy metals, fly ash, and bottom ash.
The coal industry has found several ways to reduce sulfur and other impurities from coal, as well as more effective ways of cleaning coal after it is mined. Power plants use flue gas desulfurization equipment, also known as scrubbers, to clean sulfur from the smoke before it leaves their smokestacks. Scientists are also working on new ways to reduce mercury emissions from coal-burning power plants. Research is underway to address emissions of CO2 from burning coal, including carbon capture, which separates CO2 from emissions sources and recovers it in a concentrated stream.

The US military is a bigger polluter than 100 countries
The US military is one of the largest polluters in US history, with a carbon footprint that surpasses that of over 100 countries. The US military is a vast infrastructure that relies on a global network of cargo planes, trucks, and container ships to supply its operations. According to a report by Durham and Lancaster University, the US military consumes more liquid fuels and emits more carbon dioxide than most countries. If the US military were a country, it would rank 47th in the world for greenhouse gas emissions.
The US military's contribution to pollution goes beyond carbon emissions. Military expansion has negatively impacted air quality, ecosystems, biodiversity, and the health of local populations living around bases. The US military has a long history of nuclear testing and the use of toxic chemicals, which have contaminated land, water, and soil. Additionally, the US military is responsible for wasting large amounts of land, with almost 900 of the 1,200 Superfund sites in the US being abandoned military sites.
The US military's pollution has also had a significant impact on the economies and populations of countries where the US has waged war, such as Iraq and Afghanistan. The US military's routine incineration of plastics, electronics, and other toxic waste in these countries has left a legacy of environmental damage and major health problems.
The US military has recognized the potential consequences of climate change and its own contribution to the problem. However, the military's efforts to reduce its impact, such as investing in alternative energy sources like biofuels, have been minimal compared to its massive spending on fossil fuels. The US economy's reliance on military expansion and the flow of state subsidies into key industries have also hindered progress in reducing the military's carbon footprint.
Addressing the US military's carbon bootprint is crucial for effective climate change mitigation, and it requires significant reductions in the Pentagon's budget and capacity to wage war. The money currently spent on fueling the US military could be redirected towards funding green initiatives and a Green New Deal.

The US's dependence on fossil fuels
The US has a long history of dependence on fossil fuels, which have powered its economy for over 150 years. Fossil fuels, including coal, oil, and natural gas, have been the predominant energy sources in the country, supplying about 80% of its total energy consumption for more than a century. In recent years, there has been a shift in the types of fossil fuels used, with natural gas and petroleum liquids seeing increased domestic production and consumption. Despite this shift, the overall reliance on fossil fuels remains high, with fossil fuels accounting for about 84% of total US primary energy production in 2023.
This heavy reliance on fossil fuels has had significant consequences for the environment. Burning fossil fuels releases carbon and other greenhouse gases into the atmosphere, contributing to climate change. In 2019, the burning of fossil fuels accounted for 74% of US greenhouse gas emissions. The impact of these emissions is felt not only within the US but globally, as the US is the biggest carbon polluter in history. The country's top 50 polluting facilities, mostly power plants, were responsible for nearly 7% of the nation's total greenhouse gas emissions in 2022.
While there have been efforts to transition to renewable energy sources, they have had a slow start. In 2020, renewable energy accounted for only about 20% of US electricity generation. However, the cost of renewable energy is falling, and wind and solar power are seeing significant growth. Additionally, new technologies like electric cars and advancements in energy storage are opening up possibilities for a wider shift towards cleaner energy sources.
To reduce their dependence on fossil fuels, the US can implement several strategies. Firstly, improving energy efficiency in buildings, vehicles, and industrial processes can help reduce overall energy demand and emissions. Secondly, orienting cities and towns towards public transit, walking, and biking can further decrease the reliance on fossil fuels for transportation. Lastly, carbon capture and storage (CCS) technology can be employed to collect and inject carbon emitted by the fossil fuel sector back into the earth, although this should not be an excuse to continue burning fossil fuels unabated.
In conclusion, the US has a long-standing dependence on fossil fuels, which has resulted in significant environmental consequences. While efforts to transition to renewable energy sources are underway, more urgent action is needed to reduce the country's reliance on fossil fuels and mitigate their impact on the climate. A combination of policy changes, technological advancements, and shifts in energy consumption patterns can help the US move towards a more sustainable and environmentally friendly energy future.

The Biden administration's new rules to limit pollution
In 2024, the Biden-Harris Administration introduced a suite of standards aimed at reducing pollution from fossil fuel-fired power plants. The new rules are designed to protect communities from pollution, improve public health, and confront the climate crisis without disrupting the delivery of electricity.
One of the rules requires existing coal-fired power plants to control 90% of their carbon pollution by 2039. The EPA's Clean Air Act standards for existing coal-fired and new natural gas-fired power plants limit the amount of carbon pollution these sources can emit, based on proven and cost-effective control technologies. The regulatory impact analysis projects reductions of 1.38 billion metric tons of carbon pollution overall through 2047.
The Biden-Harris Administration is also supporting communities in transitioning to a cleaner transportation future. In March 2024, the EPA announced final national pollution standards for passenger cars, light-duty trucks, and medium-duty vehicles for model years 2027 through 2032 and beyond. These standards are expected to avoid more than 7 billion tons of carbon emissions, improve air quality, and provide nearly $100 billion in annual net benefits to society, including significant public health and economic benefits.
Additionally, the Biden-Harris Administration has finalized stronger clean air standards for chemical plants, dramatically reducing emissions of toxic chemicals like ethylene oxide and chloroprene, which are linked to elevated cancer risks in surrounding communities. These rules advance President Biden's Cancer Moonshot Initiative and his commitment to environmental justice.
Overall, the Biden-Harris Administration's new rules to limit pollution are comprehensive and far-reaching, addressing pollution from power plants, vehicles, and chemical plants. These rules are expected to have significant benefits for public health, the environment, and the economy.
