A lot of carbon dioxide emissions are from cars and factories. However, an often overlooked source of greenhouse gas (methane) is cows. Cows actually add more to the greenhouse effect than cars do.
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.
Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity is the main source of air pollution, in the form of carbon dioxide (CO2) (a greenhouse gas classified as a pollutant when it is added to the atmosphere).
Water vapor. It accounts for almost all of the green house effect, over 70%. CO2 accounts for 5%.A:The main greenhouse gas as far as global warming is concerned is carbon dioxide.
Carbon dioxide is the main greenhouse gas. It also causes global warming.
Renewable energy produces practically no greenhouse gases, compared to fossil fuels (coal, oil and natural gas). Hydroelectric power has very little greenhouse gas emissions associated with it. Wind and solar power tend to have low emissions. Geothermal energy also has low emissions. Nuclear power has some greenhouse gas emissions associated with the mining and refining of uranium ore, but not a lot.
Wave power generates electricity from the movement of ocean waves, a renewable energy source that does not produce greenhouse gas emissions. By using wave power to generate electricity, we can reduce our reliance on fossil fuels, which are a major source of greenhouse gas emissions when burned for energy production. This can help reduce overall greenhouse gas emissions and combat climate change.
The main function of use of methane gas is that it is the main constituent of the natural gas which is used as a fuel in automobiles and for domestic uses as well. It is very clean and also provides a high calorific value.
The main gas present in biogas is methane (CH4), which is produced through the anaerobic digestion of organic matter by microorganisms. Methane is a potent greenhouse gas, but when captured and used as biogas, it can be a renewable energy source for heating, electricity generation, and vehicle fuel.
