Where Greenhouse Gases Come From In the United States, greenhouse gas emissions come primarily from the burning of fossil fuels in energy use. Carbon Dioxide. Carbon Dioxide is the main greenhouse gas. In 2013, 82% of human-caused greenhouse gas emissions were carbon dioxide emissions, resulting from the burning of fossil fuels, solid waste, trees, wood, and other chemical reactions. Methane and Other Gases.

- There are four major pollutants that come from cars: 1  A car emits carbon monoxide when the carbon in fuel doesn't burn completely. 2  A car's exhaust emits hydrocarbons, a toxic compound of hydrogen and carbon.

Are CO2 levels increasing? CO2 emissions from land use was estimated at 1.2 ± 0.4 gigatonnes of carbon in 2008. Note the proportionally higher uncertainty compared to fossil fuel emissions. Over this period, an average of 43% of each year's CO2 emissions remained in the atmosphere although there is much year-to-year variability.

Where does methane come from? Methane is emitted from a variety of both human-related (anthropogenic) and natural sources. Human-related activities include fossil fuel production, animal husbandry (enteric fermentation in livestock and manure management), rice cultivation, biomass burning, and waste management.lso, the implementation of technologies to capture and utilize methane from sources such as landfills, coal mines, and manure management systems affects the emission levels from these sources. Emission inventories are prepared to determine the contribution from different sources.

How does carbon dioxide contribute to global warming? Carbon dioxide (CO2) is a powerful greenhouse gas. In the atmosphere it captures the sun's heat and warms the planet. This is part of the natural carbon cycle. Additional carbon dioxide comes from burning fossil fuels (coal, oil and natural gas).

- Methane can come from many sources, both natural and manmade. But the largest source of industrial emissions is the oil and gas industry. By emitting just a little bit of methane, mankind is greatly accelerating the rate of climatic change.

Air pollution Photo: Air pollution is obvious when it pours from a smokestack (chimney), but it's not always so easy to spot. This smoke comes from a coal-fired power plant and its pollutants include sulfur dioxide and the greenhouse gas carbon dioxide.hen we think of pollution, we tend to think it's a problem that humans cause through ignorance or stupidity—and that's certainly true, some of the time. However, it's important to remember that some kinds of air pollution are produced naturally.

Largest global emitters of carbon dioxide by country 2016 The statistic reflects the largest producers of energy-related carbon dioxide emissions in 2014, based on their share of global energy-related CO2 emissions. China was the biggest emitter of carbon dioxide; the country accounted for around 23.4 percent of global CO2 emissions that year.n order to save CO2 emissions, the United States, China, India and Brazil have started to add renewable sources to the energy mix. In 2013, the share of renewables in U.S. energy consumption rose to over 20 percent. The country is also counted among the key producers of wind and solar energy.

Greenhouse Effect Carbon Dioxide (CO2): Carbon dioxide enters the atmosphere through the burning of fossil fuels (oil, natural gas, and coal), solid waste, trees and wood products, and also as a result of other chemical reactions (e.g., manufacture of cement).

The major sources for carbon dioxide emissions Though only a small amount of the atmosphere is made of CO2, this is still a huge amount in weight and volume. It is reasonable to wonder what the major sources are. The greatest amount of carbon dioxide is locked up in plants, rocks, and the oceans. It should not be surprising that these each contribute more CO2 emissions than any other sources.

Main sources of carbon dioxide emissions 42.84 percent of all naturally produced carbon dioxide emissions come from ocean-atmosphere exchange. Other important natural sources include plant and animal respiration (28.56%) as well as soil respiration and decomposition (28.56%). A minor amount is also created by volcanic eruptions (0.03%).7 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil. The remainder results from the clearing of forests and other land use changes (9%), as well as some industrial processes such as cement manufacturing (4%).

Causes of Global Warming One of the first things the IPCC learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2.
