The gas which is the main pollutant responsible for Global Warming is Carbon dioxide. It is present in the earth’s atmosphere, and the natural circulation of carbon occurs between the atmosphere, oceans, soil, plants, and animals. Moreover, Carbon dioxide is a greenhouse gas that is harmful to the environment. It is emitted through the activities of humans and is the main cause of global warming, along with methane and other gases.

Gas Responsible for Global Warming

The main gas which is a major pollutant leading to Global Warming is Carbon Dioxide. Its chemical formula is denoted by CO2. Human activities have elevated the emission of carbon into the atmosphere since the industrial revolution. Carbon dioxide gas is emitted into the atmosphere by the combustion of fossil fuels like coal, oil, and natural gas.

The gases like Carbon dioxide, Methane, Nitrous oxide, Ozone, etc., trap the heat in the atmosphere. The phenomenon of heat trap is referred to as the greenhouse effect, and the gases that are involved in the process are known as greenhouse gases.

  • Methane gas is emitted into the atmosphere during the production and transport of coal, natural gas, and oil.
  • Nitrous oxide is produced during the treatment of wastewater, agricultural land use, industrial activities, combustion of solid waste, etc.
  • Carbon dioxide is harmful to the environment and has increased the level of heat on the earth’s surface, leading to rising temperatures and, ultimately, global warming.


Which Gas is the Main Pollutant Responsible for Global Warming?

Carbon dioxide Gas is the Main Pollutant Responsible for Global Warming. It is released into the atmosphere because of human activities. These activities include but are not limited to burning coal, natural gas, oil, solid waste, trees, and other biological materials.
