The two largest sources of greenhouse gas emissions in the US are transportation (e.g. cars, trucks, planes) and electricity generation (e.g. burning fossil fuels for power). These sectors account for the majority of the country's greenhouse gas emissions.
CO2 acts as an acid when absorbed by the ocean.
Global warming was said to have increased due to greenhouse gas emissions.
To calculate the CO2 equivalent for a greenhouse gas emission, you multiply the amount of the greenhouse gas emitted by its global warming potential (GWP) factor. The GWP factor represents how much heat a gas traps in the atmosphere compared to carbon dioxide over a specific time period, usually 100 years. This calculation helps standardize different greenhouse gases' impacts on global warming by expressing them in terms of carbon dioxide.
Geothermal energy systems typically emit minimal greenhouse gases compared to fossil fuels. The primary greenhouse gas released is carbon dioxide (CO2), although the levels are significantly lower than those from coal or natural gas plants. Other gases, such as methane (CH4) and trace amounts of hydrogen sulfide (H2S), can also be released, but these emissions are generally small in comparison to the overall greenhouse gas emissions from conventional energy sources. Overall, geothermal energy is considered a low-emission energy source.
The largest source of CO2 emissions globally is the combustion of fossil fuels such as coal, oil and gas in power plants, automobiles, industrial facilities and other sources.
The US is responsible for around 15% of the world's carbon dioxide emissions from burning fossil fuels. This makes it one of the largest contributors to global greenhouse gas emissions.
Burning fossil fuels, such as coal, oil, and natural gas, produces the largest amount of greenhouse gases, particularly carbon dioxide (CO2). These emissions contribute significantly to global warming and climate change. Transitioning to renewable energy sources like solar, wind, and hydroelectric power can help reduce greenhouse gas emissions.
Petroleum, natural gas, and coal
All of it . . . the largest amount of greenhouse gas is plain old water vapor. (Humidity) Without the greenhouse gasses, the Earth would be an icy ball with no animals, plants, or humans.

The largest contributor of greenhouse gases into the atmosphere is the oil and gas company Saudi Aramco. They have consistently been identified as one of the biggest emitters of carbon dioxide globally.
