Coal is the most polluting energy source
Fossil fuels, including coal, oil, and gas, are the largest source of global carbon dioxide (CO2) emissions. In 2019, fossil fuels accounted for more than 81% of global energy production, with coal consistently ranking second in the global energy mix at more than a quarter (25%) of the total. Coal is a critical energy source, providing over one-third of the world's electricity. However, it is also the most polluting energy source, with the highest CO2 emissions per unit of energy and the most local air pollution.
Coal is a carbon-rich black rock formed over thousands of years through heat and pressure underground.

In 2022, coal-fired power generation in the United States accounted for about 19% of total energy-related CO2 emissions and 55% of CO2 emissions from the electric power sector. Additionally, coal mining and power plants have significant environmental and health impacts beyond carbon emissions.
Coal mining operations, such as surface and mountaintop removal mining, can alter landscapes and cause pollution. In the United States, surface mines contributed to about 63% of coal production in 2022, removing soil and rock above coal deposits. Mountaintop removal mining has impacted the Appalachian Mountains, changing the geography and affecting streams and valleys. The waste and pollutants generated by coal mining and power plants can contaminate waterways and drinking water supplies, impacting aquatic life and human health.
Coal-fired power plants are linked to air pollution, with emissions of sulfur dioxide, nitrogen oxides, particulate matter, and mercury. These pollutants have been associated with asthma, cancer, heart and lung ailments, and neurological problems. While efforts have been made to reduce emissions through regulations, pollution control technologies, and carbon capture, the transition away from coal towards cleaner energy sources is essential to mitigate coal's worst impacts on the environment and human health.
Despite the recognition of coal's polluting nature, coal-fired power generation continues to be relied upon in various parts of the world. For instance, China added 11 GW of coal-fired power plants in 2022, and India experienced a significant increase in coal-fired generation to meet rising electricity demands. Even the European Union and the United Kingdom have resorted to coal to enhance energy security amid the energy crisis caused by Russia's invasion of Ukraine. Nevertheless, the urgency of addressing climate change and reducing emissions underscores the need to phase out coal and transition to low-carbon energy sources.
