Nuclear energy is a topic of much debate, with some arguing that it is a clean and reliable source of energy that can help combat climate change and air pollution, while others point to the risks associated with nuclear power, such as radioactive waste and the potential for disasters. Nuclear power plants emit almost no air pollutants during operation, and unlike coal, oil, or gas, they do not release greenhouse gases. However, the nuclear fuel cycle, from uranium mining to nuclear waste disposal, can have significant environmental and health impacts. The question of whether nuclear energy produces air pollution is complex and multifaceted, involving considerations of energy alternatives, ecological footprint, public health, and safety.

Nuclear power plants emit no air pollutants during operation
Nuclear power plants do not release any greenhouse gases during their operation, unlike coal, oil, or gas. However, it is important to note that nuclear energy does produce radioactive waste, which must be carefully stored and can accumulate over time, increasing the risk of radioactive leaks. Most fuel rods are stored at the same site as the reactor that consumed them, resulting in hundreds of radioactive waste sites worldwide. Uranium mill tailings, a type of low-level radioactive waste, are usually placed near the processing facility and covered with a sealing barrier to prevent radon gas from escaping into the atmosphere.
While nuclear energy does not emit air pollutants during operation, there are other environmental considerations. Uranium mining, for instance, has been linked to lung cancer in miners due to the presence of natural radon gas. Additionally, nuclear energy has a significant impact on land use, which can potentially lead to ecosystem degradation. The nuclear industry has proposed new reactor designs that are allegedly safer, but these designs are generally untested, and there are no guarantees that they will be operated correctly or be immune to natural disasters or acts of terrorism.
Despite these concerns, nuclear power plays a crucial role in reducing air pollution and is key in the fight against climate change and the prevention of respiratory health conditions. Shutting down nuclear power plants could lead to an increase in air pollution as coal, gas, and oil sources ramp up to compensate for the loss in energy production. An MIT study found that retiring U.S. nuclear power plants could result in more than 5,000 premature deaths due to increased air pollution. Therefore, nuclear power remains an important part of the energy mix, alongside other clean energy sources such as solar, hydropower, wind, and geothermal electricity.

Nuclear energy is a low-carbon energy source
A 2019 study by the International Energy Agency found that nuclear power helped avoid over 60 gigatons of net greenhouse gas emissions globally in the last 50 years. This prevented approximately 2 million deaths that could have been caused by air pollution. Additionally, an MIT study from 2023 showed that shutting down nuclear power plants could lead to an increase in air pollution as coal, gas, and oil sources would need to ramp up to compensate for the loss of nuclear power. The study estimated that this increase in air pollution could result in up to 5,200 additional pollution-related deaths in a single year.
While nuclear energy does not produce air pollution during its operation, it is important to consider the potential impacts of uranium mining, nuclear waste management, and accidents. Uranium mining has been linked to lung cancer and other respiratory diseases among miners due to the presence of radon gas. Nuclear waste, such as spent reactor fuel, is highly radioactive and must be carefully stored and disposed of to prevent leaks that could harm the environment and human health.
Despite these challenges, nuclear energy is still considered a low-carbon energy source that can help meet global energy demands while reducing air pollution. It is also more reliable and requires less land use compared to other clean energy sources like solar, hydropower, and wind. However, the high cost and long planning time of nuclear power plants are often cited as drawbacks, along with the potential risks associated with weapons proliferation, meltdowns, and accidents.
In summary, nuclear energy is a low-carbon energy source that has the potential to significantly reduce air pollution and mitigate climate change. While there are challenges and risks associated with nuclear power, it remains an important part of the global energy mix and can contribute to a cleaner and more sustainable future.

Nuclear energy reduces greenhouse gas emissions
Nuclear energy is a low-carbon energy source that can play a significant role in reducing greenhouse gas emissions. Unlike coal, oil, or natural gas, nuclear power does not release any greenhouse gases during its operation. This makes it a valuable tool in the fight against climate change and the prevention of respiratory health conditions caused by air pollution.
According to the International Energy Agency, nuclear energy has helped avoid over 60 gigatons of CO2-equivalent net greenhouse gas emissions globally in the last 50 years. This has prevented approximately 2 million deaths that could have been caused by air pollution. Nuclear power plants produce virtually no air pollutants during their operation, making them a clean source of energy that can help meet global climate change goals.
The use of nuclear energy today avoids emissions roughly equivalent to removing one-third of all cars from the world's roads. This is especially important as modern society becomes increasingly dependent on electricity, with demand steadily rising as transport, domestic heating, and industrial processes become more electrified. Nuclear energy has the potential to provide a continuous and reliable supply of energy while also reducing greenhouse gas emissions.
Nuclear power can directly replace fossil fuel plants, avoiding the combustion of fossil fuels for electricity generation. France, for example, generates over 70% of its electricity from nuclear power, and its electricity sector emissions are one-sixth of the European average. This shows that nuclear energy can be expanded rapidly to combat climate change effectively.
In addition to electricity generation, nuclear power can also be used to produce hydrogen, which is an increasingly important future fuel option for the transport sector. Hydrogen from nuclear energy can also be used for energy storage and to support industrial processes such as steel and ammonia production. Non-energy nuclear applications, such as radiation technology, can also play a role in cleaning up air pollution and protecting the environment.

Nuclear energy waste must be carefully stored
Nuclear energy does not produce air pollution. In fact, it helps to limit it. However, it does produce radioactive waste that must be carefully stored and disposed of.
Nuclear power plants emit virtually no air pollutants during their operation. Unlike coal, oil, or gas, nuclear power does not release any greenhouse gases. A 2019 study from the International Energy Agency found that over 60 gigatons of CO2-equivalent net GHG emissions were avoided globally over the last 50 years thanks to nuclear power. This prevented the death of approximately 2 million people who could have died due to air pollution.
However, nuclear power does produce radioactive waste that must be carefully stored and disposed of. All parts of the nuclear fuel cycle produce some radioactive waste, and the cost of managing and disposing of this waste is part of the electricity cost. Radioactive waste is not unique to the nuclear fuel cycle; radioactive materials are used extensively in medicine, agriculture, research, manufacturing, non-destructive testing, and minerals exploration.
There are three main types of nuclear waste: high-level, transuranic, and low-level waste. Each type must be disposed of according to its risk to human health and the environment. For example, high-level nuclear waste remains highly radioactive for tens of thousands of years and must be disposed of in a way that can securely isolate it for a long period. Low-level waste must be disposed of at a low-level waste disposal facility.
The safe disposal of nuclear waste typically involves storing it in specially designed pools of water, which cool the waste and act as a radiation shield, or in specially designed dry storage containers. An increasing number of reactor operators now store their older waste in dry storage facilities using special outdoor concrete or steel containers with air cooling.
Despite the progress made in safely managing nuclear waste, no country in the world has yet come up with a reliable permanent solution to store it. While Finland’s repository might be the world’s first successful long-term storage facility, doubts remain about its longevity. The extremely high costs and potentially destructive consequences of a failure are significant drawbacks of this method.

Uranium mining causes lung cancer in miners
Nuclear energy has the potential to play a significant role in limiting air pollutants and GHG emissions while meeting global energy needs. Unlike coal, oil, or gas, nuclear power does not release any greenhouse gases during its operation. However, the production of nuclear energy is not entirely free of air pollution. Uranium mining, for instance, has been linked to lung cancer in miners.
Uranium mining has been a prominent industry in the Four Corners region of the Southwestern United States (Arizona, Colorado, New Mexico, and Utah), as well as on Native American lands. While the industry collapsed in the late 1980s, it employed thousands of individuals who continue to face an elevated risk of developing lung cancer due to their occupational exposure to radon progeny. Radon is a radioactive gas produced by the decay of radium, which is present in uranium mill tailings.
The case of a 72-year-old Navajo male who worked for 17 years as an underground uranium miner exemplifies the health risks faced by these miners. Despite being a lifelong nonsmoker with no other significant occupational or environmental exposures, he developed lung cancer 22 years after leaving the mining industry. Radon decay products, silica, and diesel exhaust are among the respiratory carcinogens that miners like him commonly encountered.
In recognition of the health risks faced by uranium miners, the Radiation Exposure Compensation Act (RECA) was passed by the U.S. Congress in 1990. This legislation provides partial restitution to individuals harmed by radiation exposure resulting from underground uranium mining and above-ground nuclear tests in Nevada.
